Hate the reddit style of handling comments. Even the fact that they are called comments and not replies, or posts even.

>>57050314
Well, didn't realize I liked "replies" better. I'll change that.

>Reddit style
Reddit wasn't the first to use tree-style threads. Still I don't think that's the reason why Reddit sucks

Never said it was. Doesn't change anything i said.

Anyone know where I can get oracle ebooks? Especially the dba side of things? Looking for some good books by Thomas Kyte and Jonathan Lewis I think. I have already checked the gentoomen library though thats the version I downloaded a year or more ago and should check for updates.

Cant find them on tpd and dont know which kick ass sites are trustworthy. Not that this search would likely trigger attention.

Anyone recommend a ebook torrent site?

>>57050276
Well what the fuck, how do I get better?

>>57050378
Are you able to describe why you hate it? Posts (a.k.a nodes) are sorted from new to old, so it gives more visibility to recent posts and it's easier to understand from an hierarchical point of view

I'm also planning to add an interactive map for browsing each roots. :^)

/dpt/ I'm having trouble looking for a coding job and could use some advice. all these places i'm applying to want experience with AWS, Redis, MySQL or Postgress or MongoDB, hadoop, rabbitmq, and a bunch of other things I have no experience using.

Coming to anywhere on 4chan for help probably wasn't the best idea.

Learn them and make something on your own. It shows initiative and builds experience. If you're talented you may make something people like and be able to sell/make money off that.

What work are you doing? Yes a good study of C will help but where will you get it? That matters. If you dont know python learn it its everywhere and spreading. Then learn enough pearl and lua to read the old fags work they left behind. After that if you have the languages you need to work maybe look at C and do some of the free computer science courses available on websites now. You can get those in python by the way study data objects and shit.

The hierarchical tree structure may not necessarily be that bad, but i hate how you have to click the teeny tiny comment button to enter the thread. I just want to click anywhere on the post.
And you get no sense for the discussion going on in a thread when all you get is the op, or worse only the heading, when casually scrolling past.
It makes me feel as if participating in any thread is discouraged.

>>57050596

>>57050616
Well my school is making me learn Java and before that I had to learn Visual Basic skills I feel like I should be learning C because everyone talks about how good it is. I don't want to be pajeet-tier, I want to be actually really good at what I do.

>>57050563
In that case you need to ask better questions, and not impossible to answer generalities that only invite platitudes and shitposting.

>>57050661

Dont touch C until you are productive with the languages you are learning. Youll end up burred. Learn C after you are already on your feet. Aim for pajeet tier before you ascend past it.

One must pass through the clouds to reach the sky.

Anyone have that image with all the programming books that says own/read under them?

>>57050676
I learned C as my first real programming language.

>>57050690
No. A collared shirt and jeans.

>>57050639
I know this feeling and I'm taking this into account. I'm assuming sorting according to time (newest first) is enough to prevent the "bubble effect" you see on Reddit.

>>57050563
Okay, then. Working at being a better programmer makes you a better programmer. You don't attain "Programmer", you do as programmer does. I can't shit in a can, have you smell it and suddenly make you a better programmer. What you need to do is take the time to understand what a computer is doing and how it is doing it, not who is doing it. Once you have managed the prospects of a computer as it is made not created then you will have an understanding upon which you can apply the constructs of any particular language, even javascript. But with any imparticular language comes the imparticular syntax and foundation of reasoning, which will manifest as very specific understanding and intuition. C is the bare minimum of all that but also offers up fewer comforts in the way libraries and conveniences.

You ever think maybe you're not gay and just a fucking ass kisser?

Was looking at an XORing function and noticed something i had never seen before in C++:

string p;
    for(unsigned int i = 0; i < s.size(); ++i)
    {
        p += (s[i]^k[i]) ? "1" : "0";
    }

Do any c++ wizards know what exactly the "? "1": "0"; part means?

What if he doesn't want to code for enterprise in C? I think he's better off learning normal C before he goes into a grouped heuristic as found in the more modern languages. There's a reason fuckers are always pushing NODE as the ADT.

i don't have JS disabled. i just noticed by palemoon build is a little out of date, though. i'll try again after updating. props for avoiding bloat/tracking but i'm personally not a fan of heirarchical comment systems. they don't scale well; under real-world use it begs the use of voted ordering and hiding and shit which in practice tends to elevate the uncreative/status quo (see: Reddit; arrested development references, completing song lyrics, and a bunch of other useless shit that ends up having a surprisingly significant and negative impact on the culture of the site). Reddit is okay for content aggregation i guess, but it's shitty for discussion largely because of this. chan-style design is better in that regard for a number of reasons and that's why i come here to actually talk about shit

>>57050698
Sorting by latest reply time, or by op time? The former seems to work for 4chan at least. The latter may, or may not, make the board seem to static. I don't know.

Also, i have bad eyesight and i hate it when people go full applefag and make the design half unusable in the interest of aesthetic, even a minimalist aesthetic. Right now the design is inclining in that direction.

>>57050831
I don't understand what exactly its testing; the p+= part isn't a test, so how can it be saying if its true/false 1, else 0?

>>57050867
>http://www.cprogramming.com/reference/operators/ternary-operator.html
it's saying

if (s[i]^k[i]) {
    p+= "1";
} else {
    p += "0";
}

>>57050879
But I am a woman

>>57050886
How can the expression

s[i]^k[i]

be put in an if statement when its a bitwise operation, not a test? What is it "if-ing" so to speak? Or rather, in which situations would it evalute to p+= 1, or p+=0?

I'm 48, is it too late to start?

>>57050913
Then by default you'll never be top tier, you'll still have plenty of job opportunities because of quotas and lack of female programmers, due to the amount of work it takes to learn properly.

When I include GLFW3 and link it, it cannot find "glcorearb.h"

I've spent way too long on this garbage

>>57050934
remember that in C (and C++), 0 is false, non-zero is true. So if s[i]^k[i] returns anything but 0, "1" will be concatenated to p, if it returns 0, "0" will be concatenated to p.

>>57050822
It's true flat threads in chans force the users to interact with it thus making the thread feels more lively and the discussion actually go somewhere.
But I definitely think hierarchical threads with proper sorting can also achieve this. It's even easier to dig into a thread when their are already lots of replies. Also, you are guaranteed to get visibility since new replies are always showed first.

>>57050834
Every nodes are sorted from new to old, even for the threads on the main page (no bumping currently).
The design is (too?) small to allow more content to be shown, thus making following the thread easier. I tried to increase the font size but didn't find something I could stick too

>>57050913
Did you not read my post?

Can't you use your critical thinking skills to maybe figure out my meaning? There aren't instructions to learning programming. Actually, what do you even want to start at?

Anyway, I think you've just illustrated my point a bit. There is no instruction set. There is no one to tell you what's there. You have to make it yourself. The only thing holding you back then is the people and the matter in the situation. If you are speaking to people and they say no, but you think yes, then you only believe no because they say no and thus can't really be expected to come up with a solution to your problem. You create a conflict for yourself. What you have then is the expectancy that someone will come along and show you how to figure that "yes, you can" start coding right now and today.

You said you are 23? and female? I'm not a professional coder but I can work with you for the price of unrequited love and daily chats. You don't have to do the love part. I just really want someone to work with and here on 4chan only stormtroopers reply. I'd be grateful that you were older than the usual shits we have on here. But please don't take advantage of my desire to work with other people.

Should we attempt to make contact?

Help me out, algorithmicists.
I implemented a very basic Ant Colony to solve TSP for large (>100,000) point graphs.
I use kd-trees to produce some k-neighbors for each point.

While it works (poorly, it only optimizes Nearest-Neighbor by a factor of 1/2), I was wondering how people normally implement Ant Colony for huge graphs.

Naturally, you can't use a table to track pheromones (a 100,000x100,000 table of doubles costs 80 gigabytes), so what I've been doing is keeping track of edges from point-to-point.
The downside of doing this is that it's unidirectional (I can't update pheromones backwards because then I'd be updating pheromones multiple times)

What's a more sane way of managing pheromones in ACO for large graphs?

I should clarify, I have already taken a VB class and my first Java. Also my university makes us learn COBOL but they don't teach C or C++. If I already have a decent grasp of Java and I understand the basic concepts of programming, would it be okay to just dabble a bit in C?

>>57051078
I can't say, I'm not a mental health professional. The fact of the matter is that when I lie down to sleep nothing happens, I can't grasp that "sense" that guides me into sleep, but I become uncomfortable in a way I have to attribute to my inability to sleep

>>57050993
yeah, i'm not of the belief that there's no right way to do it. but just something to keep in mind. i'm also bothered by only really being able to reply to one post. it would be nice to be able to inline-link posts other than the one being directly replied to. you could do it like 4chan, at least for posts in the same thread, where you just get a div showing the post on mouseover, or some similar approach. ideally something better than just a permalink to the post with no embedded ui functionality like Reddit

>>57051033
If I were a girl I would contact you anon.

>>57051057
C is just going to force you to rethink problems in lieu of implementation details about structures you may have learned in Java. You'll never hear it this way because we are running on enterprise wire but it's the truth. What a lot of enterprise manages then in those cases is process splitting through structures, which, really, could be done using a JavaScript UI. C will essentially teach you why we fear the robot uprising and, probably, a bit more about yourself. Java was a good start but it may depress you how difficult it is to use some of the stuff you get out of a simple import in java. But it will amaze you just how comfortable you can be under supposed heavy duress because you aren't making calls to build irrational models for enterprise logisctics consumption.

Someone mentioned a simple website running 1000+ lines of code to put time on an html body. That's what the rest of that code is for. Some of that code is calls to signatures on a remote db, too. Sucks.

>>57051109
You used to fall asleep with the TV or a fan on for comfort and found a noise that runs at those similar levels running, more or less, all the time. This desensitizes you and now you're dealing with some of the stresses you had growing up. Just look around for noise algorithms and tune them til you find one that relaxes you. Or try hypnosis mp3s. There's a good one on the lixny server if you're not afraid of bait directories made by the trolls on here. Though, lixny, might be a honeypot. Who knows.

Do you exercise at all?

Generally speaking, if you're sitting down all day or even working retail on your feet but not really moving, you're not tiring your body out enough to sleep. Start working up to a 5k jog every day (should only take about 20-25minutes) and you'll find you sleep much better every night

For the life of me I can't figure out what I'm doing wrong. I've got a function that's supposed to find the Kth smallest element in a BST, sometimes it gives the correct answer but most of the time it doesn't. Any ideas?

void Tree::printSmallestElement(int k, Node *leaf) { // Print the Kth smallest element in the tree

    if (!leaf || k < 1) {
        return;
    }

Then 4chan is definitely the place to be.

My makefile generator in Ruby has turned into a CMakefile and general project generator, called genproject. It can more or less generate C, C++, and Java projects on the fly from templates. It's abstracted in a way right now where other project systems could be implemented for different languages.

>>57051122
Okay then no contact. I don't really feel like explaining all that in just one thread. It's a lot, and is the only reason for why I was offering my help. Attractive women don't exactly flock to 4chan, especially not /g/.

Anyway, if you're that kind of "social" your problem might be a social one and not one to do with programming, neurotypical. You could jump on the webdev bandwagon and call what you do programming but you'd just be running on estrogen then. If you jumped on the regular programming deal you'd be faced with a lot of work and tons of misinformation considering the way you seem to collect your securities for deposit. Happy hunting!

It doesn't take a terribly long time for people to git gud at programming.

I've seen Army Rangers go back to school at like, 26, and they come out as some of the best products of the university. Top notch programming abilities.

Now, the problem is that you're a woman. The problems lie in the fact that women are unwittingly trained to think that they aren't capable of doing something. They have a natural tendency to develop inferiority complexes, and as soon as the first roadblock pops up, they give up.

If you can get over your inferiority complex (based on all these posts you've made, you for sure have one), you'll be a fine programmer.
Books you should read are "Introduction to Algorithms" by Cormen et al., "Algorithms" by Dasgupta et al., and "Programming Language Pragmatics".

These are very general books which do not (necessarily) focus on any particular language. Reading through them, following the proofs, and solving the problems contained should grow your critical thinking skills.
Programming Language Pragmatics will teach you about the reasons programming languages are designed the way they are (and how they work), and the implications of that design. It works on the assumption that the reader somewhat understands how computers (or at least, memory) work at a lower level

"disorder" is probably a better word. there are people who would probably find that offensive, but the problem there is really just that they're thinking of words like "disorder" or "abnormality" as having intrinsically negative connotations even though they really shouldn't. if there was a categorical mental abnormality that had a generally positive effect but was without a doubt extreme and highly uncommon, it would probably still be called a disorder. i've studied sex, sexuality, gender dysphoria, etc. fairly extensively (personally not academically, but i'd wager quite a bit more than the average person), and i'd call it a disorder, but i mean that in a purely clinical way. it is what it is. i think it would be much better if people approached it in this way. the liberal sentiment lately seems to focus on avoiding anything that could be perceived as implying any kind of negativity, but i don't think this ends up helping in the end because it discourages academic/clinical discussion, which is the context in which we should really be discussing these things. better understanding is better for everybody

>>57051433
I unfortunately do not have a good source on a book regarding lower level computer architecture, but you don't need to understand the nitty gritty of the CPU pipeline to understand how your program executes.

Basically, all you need to know about physical memory is that it's a single bigass array of bytes. Look that up if you have to.

Introduction to Algorithms is designed to be -comprehensive-. Which means it's good for beginners.

However, a flaw in all the books I recommended is that they don't teach you how to read psuedocode (an easy to read, abstract and usually non-compilable example of how an algorithm works)

>>57051451
You can find them all on http://gen.lib.rus.ec/
Programming Language Pragmatics, 4th edition is not on there however.
I bought the PDF and I stripped my personal information from it. If you need it, I can upload it over MEGA or something.

>>57051505
Honestly, pragmatics is the one I'm most interested in. I would love to get deeper into Algorithms eventually but how the languages work and interact with the hardware is really what interests me. Up to you though, no pressure if you don't feel like it.

Thanks for the other link!

>>57051505
Contd--I have actually been looking for a high quality introductory book to programming for a long time.

However, what I have instead found is that every introductory programming book I've ever read are shovelware pushed by publishing companies.
They have the strong tendency to tie the user strongly to one language, which (temporarily) limits the scope of their understanding.

Programming Language Pragmatics is good, but it's target audience are people who understand the basics of programming already.

By the way, if you open the .pdf and some error message shows up, that's a result of me stripping my personal information from the PDF. I only have a rudimentary understanding of the PDF spec, so I may have deleted objects I shouldn't have, which sometimes results in a parse error.

I like the way 4chan's posting system works because I can just mouse over the replies at the top of the post and see who's replied to you, then I can just mouse over any replies you've linked in your post to see exactly what you're replying to.

On reddit, when branches happen, it can take a few seconds to figure out who is responding to whom.

Yes, it's supposed to link the idea of a series in math as a sequence that the compiler creates with output to a discrete set that runs on a set of deviations from the result at the standard position based on offsets that integrate on key press. Something like that could be modeled by math simply and create a nice analogy for bridging the understanding between math and "computation" as shown by the C style languages and their syntax.

>>57053033

What about it?

>>57053255
Layman's terms please.

is there an easy way to shift all the elements in an array one unit left (except the first of course) in C?

aka
char *arr = { 'a', 'b',' c'}
shift(arr) = {'b','c'}

esentially, the equivalent of haskell's tail function, but in C

>>57053275
It's an example of the stuff you learn in calculus applying to programming theory through the use of applying the orders of magnitude.

The sequence exists at the assembly level. The series a bit higher. And the constants, as demonstrated by the conditions on the index/data, are all applied from "behind the scenes"/ at the point of human configuration. The discrete set part applies to the table of data that is hardcoded into the machine as it places existing values into a running table as part of a set to be evaluated to.

I feel strange right now.

sorry I still don't know why you people are memeing in C

>>57053376
Make a pointer to the array with reference to the second element. Just make sure you don't delete the original array and instead copy your new address to the old one. It might fragment your table a bit but in the case of something like that you could just recreate state when performance isn't a problem. A one byte shift won't slow you down too much.

>http://www.stroustrup.com/

>>57053449
what do you mean fragment my table?

also, I just finished making a realloc tail, why do you say to not change the original array?

I literally wouldn't need the first element anymore

>>57053376
memmove() if you actually need to move the memory, otherwise for read-only operations just increment the pointer.
arr++
arr now points to 'b'.

>>57053478
is this ground zero for bad programming paradigms?

>>57053487
but does memmove just shift and not delete the extraneous elements?

is it just
{'a', 'b', 'c'} -> {'b', 'c', 'c'}

>>57053485
because your second one references the original one and simply "forgets" to check what was at the original arrays first index.

XYaaaaaaaaaaaa123456789\0aaaaaaaaaaa

if this string represents your array, the iterator will have to course through all those 'a', right? With the original array's pointer (X) at 1 and the new array's pointer (Y) at 2 you could assign the address in Y to the pointer X and have the original pointer simply skip that first 1 upon leading the trail to the array. It will still end at the same place, just start further in. You don't save yourself any memory and you technically do less work over the same amount of memory but really who the heck would let it pile up like that and then expect it to be easy?

Whats a good language for someone who has no intention of programming professionally and just want to fuck about?

>>57053636
haskell

>>57053485
And by fragmenting your table I mean it stretches the term cogent to a bounded mean. Instead of it all being contiguous, attached at the hip kind of deal, it skips over certain portions for the sake of brevity and assumes you'll defrag the data table yourself. This was one of the first things I learned about computers. When I was like 9.

>>57053618
ok, so you're saying that a byte is negligible and just changing the pointer's address is much easier?

But seriously, I have an array of structs that grows quickly, and each struct has a pointer to a mallocd array, which in itself grows as quickly as the array itself

I need some advice on which languages to learn.

I'm a second year undergrad looking into mechanical/electrical engineering but I'm also very interested in comp sci as a back up. What are some good languages that are useful in both areas of interest?

Groovy. I have heard similarly before. Will look into.

>>57053636
I agree with the other two fags.
Haskell is the only language I've evet had fun programming in.

Its mathematical in nature, and solutions are elegant and short (haskell code is, in average, 4 times shorter than their imperative counterparts, just look at xmonad, its 1000 lines including the big ass comments explaining)


Its strongly typed, meaning that if your code compiles it will 99% of the time work as intended.

It has advanced concepts and allows one to treat functions just like any other bitch such as integers or floats.

>>57053752
Very interesting. Preffered method of learning it? Books or just diving right in?

>>57053776

I recently started learning Python through an app and am really digging it. I'm currently working but I'm planning on going back to school for Fall 2017.
This gives me about 10 months of freelance studying before I go back to school.
I'm classified as a sophomore and am wondering if in those 10 months I'm able to learn enough on the topic to not be overwhelmed by the CS classes.

Bit of a background:
I had no prior experience with CS or Computer languages before my interest piqued.
I'm going through the Computer Science modules in Khan Academy and am expecting to get a very basic grasp of the topic when I'm done.

I'm learning the basics of python right now but since I don't have a computer atm I'm unable to do any actual coding so I'm getting the basics down while I get one.

Does anon recommend any learning sources for a budding CS major?

>>57053841
what app? im beginner too.

>>57053532
Yeah it just shifts memory.
But there's no need to 'delete' anything. Presumably you have a size variable to go with your array, so just memmove and decrease your size by one, then you've 'deleted' an element.

If you read Cormen and Dasgupta's books, follow all the proofs, and do the examples, your education will already be at the same level as a junior CS major.
Programming Language Pragmatics leaks a bit into senior-level coursework, and would ideally be supplemented with some knowledge regarding Computer Architecture and Operating Systems (both optional).

>>57053846
Learn Python from SoloLearn
They have a series on programming languages. The UI is smooth and they do a good job of explaining the basics.
I'm not expecting to be have a full understanding of the language but after noticing my progress I'm expecting to at least be able to understand and type out basic code for everyday stuff.

do you belive in the unfounded principle that any code can be made elegant
yes, I know elegancy is subjective, but its in the level of beauty since some can find certain code elegant, yet everybody knows non-elegant code

>>57053915
Absolutely

What?
If you're trying to learn how to program, refer to >>57053872

If you're trying to learn C++ specifically, just use Stroustrup's books. If you don't know how to program, don't bother, because a reference textbook is a terrible place to learn from.

>const elimination

Yesterday i was told about the
>strict aliasing rule
and decided i should learn more about it, but now i'm wondering if that only applies to c and not c++, because i cant find anything about it in [Stroustrup].

>>57053478
It has been a long since I haven't seen a site without JS.

>>57054436
Strict aliasing rule also exists in the C++ standard, except breaking the rule is less obvious than in C as long as you don't use C-style casts.
For example, this code compiles (despite breaking the rule):

int i = 0x3f800000; // 1.0f in hex
float f = *(float *)(&i32);

But this one does not:

int i = 0x3f800000;
float f = *(static_cast<float *>(&i32));

C++ is deemed having a stronger type system, so this limiting yourself to C++ features should keep you safe from breaking the strict aliasing rule... except you can still break it with reinterpret_cast in place of static_cast.

>>57054626
Thanks.

i32 is just a typo, right?

>>57054704
Yes, it's supposed to be "i" instead. At first, I tested it with a int32_t (since it's the same size as float), hence the i32. Forgot to change all occurrences.

>>57054626

Kek, that's all just the properties of C++ casts. static_cast isn't for converting between pointers of different types. A C style cast isn't technically appropriate either, it's just that it tries all of the casts except for dynamic_cast, so it always works. What you want, however, is reinterpret_cast.

What exactly is the meaning of "syntactic sugar"? Aren't all languages "syntactic sugar" by definition?

What would reinterpret_cast give me, in this context?

>>57054943
it's when you have a syntactic construction that doesn't change the semantics of the language.

What's the best way to learn c# .NET when I am already decent with regular programming. I don't really care about switching to the c# syntax but I don't know how to use all of the .net components and stuff

>>57054943
basically a pretty way to express something

list comprehensions are syntactic sugar

strings are syntactic sugar for {'a','b','c','\0'}

>>57054963
there is no best way, just do your thing senpai

>>57054966
>>57054957
Sure, but aren't strings syntactic sugar for assembly calls?

>>57054976
no.

Loops and if statements are syntactic sugar for goto desu

>>57054998
no.

>>57054998
pretty much yeah

goto is recursion

https://en.wikipedia.org/wiki/Pointer_aliasing
>In C or C++, as mandated by the strict aliasing rule, pointer arguments in a function are assumed to not alias if they point to fundamentally different types

Does this mean the strict aliasing rule only applies to function parameters?

I'm having trouble finding any official source that specifies what the strict aliasing rule actually is.

>>57054945

reinterpret_cast just interprets one pointer as another pointer with complete disregard for what those pointers are pointing to.

When you do a C style cast in C++, in effect, you do the following casts in order until one of them works:

const_cast
static_cast
static_cast then const_cast
reinterpret_cast
reinterpret_cast then const_cast

6.5.7

"An object shall have its stored value accessed only by an lvalue expression that has one of
the following types:
— a type compatible with the effective type of the object,
— a qualified version of a type compatible with the effective type of the object,
— a type that is the signed or unsigned type corresponding to the effective type of the
object,
— a type that is the signed or unsigned type corresponding to a qualified version of the
effective type of the object,
— an aggregate or union type that includes one of the aforementioned types among its
members (including, recursively, a member of a subaggregate or contained union), or
— a character type."

I recommend the King James version of the C Standard, but you could always go with the original latin

How can I cast uint8_t* to uint32_t at an offset without getting an alignment compiler warning? I need it to store a byte array in a flash buffer but the function to store it only takes uint32_t* as an argument for the data.

Here's what I have now:

uint8_t transfer[33];
transfer[0] = 0x85;
uint32_t* transferName = (uint32_t*)&transfer[1];
            flash_read_user_signature(transferName, 8); //8*4 = 32 byte

That gives the warning on line 3: "cast increases required alignment of target type [-Wcast-align]"

>>57055307
Never mind I did it using memcpy

>>57050945
No. Start off with an easy language, then find a book for beginners in that language and study it thoroughly. After that look for a book about programming concepts, apply what you've learned from that book and by then, you'll know what to do next.

>>57050945
No, far from it.

>>57055242

http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1570.pdf

>>57055307
>>57055340

union {
    uint8_t u8[36];
    uint32_t u32[9];
} transfer;

transfer.u8[3] = 0x85;
uint32_t *transferName = &transfer.u32[1];

You get 3 bytes of padding onto the front, but you can force alignment.

>>57055402
What about the C++ standard?

I feel kind of guilty. He probably won't be able to switch to any other language because it will just feel shitty in comparison with Haskell.

Not really programming, but rather shitty scripting. I'm not used to Windows and I'm trying to become more familiar with batch files. (Is there an alternative? Maybe something through powershell, or etc?)

Anywho, can people point out where I'm being retarded in these?
https://github.com/kilog/ffmpeg-batfiles
I use these files on my Windows machine, personally, because I don't like GUIs- I prefer things streamlined and text-input-only if I can help it.
I know my github is lonely, but please, bear with me.

I know this is just "scripting," but please.

Just take the black pawn.

>>57055556
How?

>>57055509

1. Scripting IS programming.
2. Don't use Batch if Powershell is at all available to you. Powershell may not be the best scripting language, but it is leaps and bounds better than Batch. The only reason to use Batch scripts is if you are on old versions of Windows that don't support Powershell, or DOS.

>>57055556

>>57055564
Right, but...

...hmm. I'm not entirely sure where to start if I want to start using Powershell. I've done a few searches, but I can't quite find a way to 'hop over,' per se

Never mind, it only took me half an hour but I finally made a program without cheating

int main()
{
    char ch = 'Y';
    do {
        float num1, num2;
        cout << "Please enter your first number." << endl;
        cin >> num1;
        cout << "Please enter your second number." << endl;
        cin >> num2;
        float sum = num1 + num2;
        cout << "The sum is " << sum << "." << endl;
        cout << "Would you like to continue? Enter 'Y' for yes." << endl;
        cin >> ch;
    } while (ch == 'y' || ch == 'Y');
}

Move king forward. Pawn can't attack except diagonally, and it can't move backwards, so after 2-3 moves of the king, the black pawn is dead.During or after this, black can only really take the white pawn, thus leaving two kings on the board for a draw.

Oh I thought the puzzle was that you only have a single move

>When a pointer or reference to object whose dynamic type is DynamicType is reinterpret_cast (or C-style cast) to a pointer or reference to object of a different type AliasedType, the cast always succeeds, but the resulting pointer or reference may only be used to access the object if one of the following is true:

http://en.cppreference.com/w/cpp/language/object
>Objects of class type that declare or inherit at least one virtual function are polymorphic objects.

I understand this to mean that instances of ordinary trivial structs are not polymorhic objects, which means that they do not have a dynamic type.
Does this mean that i can cast pointers between trivial structs without violating the strict aliasing rule?

>>57055651

The wording does suggest that, but it is provable that it can't be tied in one move.

>>57055685

You can reinterpret cast any pointer to any other kind of pointer. But that is undefined behavior.

>>57055564
Batch is fine if all you're doing is making simple calls like using it like a windows makefile calling vcvarsall on your code.

>>57055456
The solution is Kg7 (if Kh7 then h4, white loses). Shouldn't be too hard to see why.
