Point taken. Though it's still not in the top 20 of programming languages.

Made a thread about MiniMax algorithm, though I'd like some more answers.>>61233447

I've seen it implemented in games like Tic Tac Toe using two functions, heuristic and MiniMax. I have trouble understanding the point/score system specifically. How do I assign points to what and should I do it during the game (for turns) or after a game ends (for wins/loses).

I can read pretty much all languages save for the obscure ones. I have already made a very small Tic Tac Toe game that didn't take long so it's a bit messy. All I need is to implement an AI that's not stupid.

This would be fine; a project encompassing all of this would put you miles ahead of 90% of all other developers looking for jobs.


>do you use WPF or UWP ?
Neither, most of the time. I do create simple WPF applications for people from time-to-time, but most of my dev work is purely backend automation, such as creating Azure infrastructure based on on-prem data that needs to be modified, and then system-versioned in the cloud.

Okay this is a stupid question but I've never had to do it before. What's the syntax in C for a string literal that isn't just the string in quotes. I'm forced to use this editor that doesn't display unprintable characters at all, I want to pass ASCII character 31 + the null terminator to strtok as a literal, in Vim I can just insert the character and quote it, it looks like "^_" but as 1 character, in this other editor it literally just looks like "", the character is inside the quotes but it looks like it's an empty string. Is there another way to form a string literal composed of 2 characters? I don't want to use a variable just for this.

>>61233495
>What are you working on, /g/?

I'm just starting learning C
I'm trying to make this program print me the lesser of two entered numbers.
When I run it no matter what two numbers I enter I just get 0.00000.
(Example, First number is 2 and second number is 3, it prints out "The smaller of the two numbers is: 0.0000)

#include "stdafx.h"
double min(x,y);

int main()
{
    double x, y, z;
    printf("Enter your first number\n");
    scanf("%lf", &x);
    printf("Enter your second number\n");
    scanf("%lf", &y);
    
    z = min(x,y);
    printf("The smaller of the two numbers is %lf : ",z);
    return 0;
}

double min( x, y)
{
    if (x < y)
        return x;
    else
        return y;

}

    scanf("%lf", &x);
    puts("Enter your second number");
    scanf("%lf", &y);
    z = min(x, y);
    printf("The smaller of the two numbers is : %lf", z);
    return 0;
}

stop trolling you mongoloid.
If no troll, then read k&r again.

>>61234048
For starters:
>double min(x,y);
>double min( x, y)
In C, you need to specify the types of function parameters. If x and y should be doubles, you need to specify that they should be doubles. Otherwise, they're treated as ints.

I wouldn't think this would be your problem, since casts between double and int are well defined, but try fixing it first and see if it helps.

>>61234048
Forgot the types and ordered wrong, my compiler complained about all this when I compiled your program.

#import <stdio.h>

double min(double x, double y)
{
    if (x < y)
        return x;
    else
        return y;

}

int main()
{
    double x, y, z;
    printf("Enter your first number\n");
    scanf("%lf", &x);
    printf("Enter your second number\n");
    scanf("%lf", &y);
    
    z = min(x,y);
    printf("The smaller of the two numbers is %lf : ",z);
    return 0;
}

https://stackoverflow.com/questions/1421811/how-do-i-represent-a-unicode-character-in-a-literal-string-iso-ansi-c-when-the-c


For UTF8, you have to generate the encoding yourself using rules found, for example, http://www.cogsci.ed.ac.uk/~richard/utf-8.cgi?input=e9&mode=hex here. For example, the German sharp s (ß, code point 0xdf), has the UTF8 encoding 0xc3,0x9f. Your e-acute (é, code point 0xe9) has a UTF8 encoding of 0xc3,0xa9.

And you can put arbitrary hex characters in your strings with:

char *cv = "r\xc3\xa9sum\xc3\xa9";
char *sharpS = "\xc3\x9f";

Also SAD.
Ocaml isn't even standardized language so you are making bindings for just one implementation.
Ocaml doesn't support native threading because of the design of the garbage collector.
Also ocaml has fucking ugly C interface.

Anons, I need some C++ help.

I'm using a function from a library (nftw from ftw.h, to be specific) that calls multiple times some function that I pass to it. That function I pass needs access to some variables, but I don't really want to use global variables (even though I will need access to them from other places).

What's the neatest way of wrapping it?
The way I understand it, I can't make it call a non-static method of an object, so there's no point in wrapping it in a class. So do I have to put it all in a namespace and use global variables anyway?
I might be misunderstanding this C-like way of handling things.

>>61234516
I'm not suer that's true.

>>61234564
>Isn't there already bidings for opengl for ocaml?
Probably, but I like mine because they're designed for my use.
>>61234564
>bindings for just one implementation
Yes, but if one day there is another OCaml implementation, I will provide a second set of C bindings (it's not a huge work).
>Ocaml doesn't support native threading because of the design of the garbage collector.
That's not really a problem for me.

>>61234583
The problem with that is that I need a literal string, not just the character, even though the string is only going to consist of that character.
I wish I could do some bullshit like this '31' '\0', C will automatically concat 2 string literals together into a bigger string "ab" "cd" == "abcd", I wish 2 character literals next to each other turned into a literal string. As in 'a' 'b' == "ab"

>>61234691
'a' + 'b' gives 'ab', no?

>>61234701
It would just add them together and result in a single char. i.e. 31 + \0 = 31.

  char a = 31;
  char b = '\0';
  char res = a+b;
  printf("%c\n", res);

I'm just looking for the best way to represent it, currently that's like this

"\037"

In a better editor you just do this (4chan filters out the symbol) https://ghostbin.com/paste/feh6o, in vim that looks like "^_", you can see in the gif, except it's one character, it's only represented as 2 visually.

>>61234787
Nope. C doesn't even have an equivalent to string. Your only type for representing readable text is char[].

>>61234836
It's easier to just type "\037" than all that would be required to concat 2 chars into a string.

If we're being pedantic that's not true, C strings are character arrays, an array will decay to a pointer (for strings, a pointer to the first character) but they're not the same thing. In practice this makes little difference with strings but can be important for other things.

that coins problem is old, m9. here is my solution:

int coins[] = {200, 100, 50, 20, 10, 5, 2, 1};
int max = 200;
int count[200+1];

int main()

    for(int i = 0; i < 8; i++) {
        for(int j = coins[i]; j <= max; j++) {
            count[j] += count[j-coins[i]];
        }
    }

    printf("count: %d\n", count[200]);

}

Here is also the solution for this one: >>61234908

    int sum = 0;

I have little to no programming experience, I'm trying to make a simple script in python that iterates through each character in a string that's 12 chars long, on each iteration, it should compare the character in each position against a list of 10 possible values, if one of the character matches, it should be added to a new string or list, then, just continue onto the next character position and do the same.

Basically, I have an encoded string, and I would like to decode that string using 12 lists, one list for each character position in the string, the encoded lists have 10 alphanumeric entries, I would like to use the encoded list index to get the decoded value.

encoded_string = "4d40X6LIXKOQ"

encoded_values_0 = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
encoded_values_1 = ["D", "b", "f", "d", "Z", "A", "Q", "W", "S", "C"]
encoded_values_2 = ["R", "e", "x", "1", "2", "3", "4", "5", "6", "8"]
encoded_values_3 = ["N", "4", "5", "6", "7", "8", "R", "9", "0", "Y"]
..

With the example above, the operation should convert "4d40" into "4368" using the index of encoded_possible_values_in_position_x, so far, I've managed to iterate between positions 0-12 and print them, but I have issues when I loop each position looking for the 10 values in my lists:

encoded_string = "4d40"
to_decode = list(encoded_string)
decoded = []

for i, char in enumerate(to_decode):
    for c, val in enumerate(encoded_values_0):
        if (val == char):
            decoded.append(c)
    for c, val in enumerate(encoded_values_1):
        if (val == char):
            decoded.append(c)
    for c, val in enumerate(encoded_values_2):
        if (val == char):
            decoded.append(c)
    for c, val in enumerate(encoded_values_3):
        if (val == char):
            decoded.append(c)
print decoded

this scrip seems to loop encoded_possible_values_X over the 4 positions in the list to_decode, instead of just one position, where am I fucking up?

while(function())

If you have to actually use the return value as well, unfortunately you can't do that. You have to declare it first.
Or you could do:

for (char *var; *var = function();) {...}

I have seen very aesthetic way to populate an array, but I forgot it.

Lest say I have function that takes int as argument and inside this function I want to create an array of this size.

ie

for arg 4
arr = [0 ,1 ,2 ,3]

Now I know I could use just

for i in range(4):
    arr.append(i)

but I have seen very elegant "oneliner" for populating an array.

Any ideas how to make it shorter?

I'd probably use it if I had to check for anything besides NULL, but the issue is scoping var to only live inside of while. In actuality I'd probably just use the one that checks for NULL as well as throw a condition inside the loop for whatever else I was checking for.

I'm just really surprised you can't check the return value of an assignment when it's paired with the type declaration, and I don't think you can separate the 2.

It sucks that neither of these are legal.

No. The only difference is effectively in flags to say "this method is only callable from *these* contexts", and the generated code doesn't really give a fuck about those.

I use it, I like it. I'd never recommend it or any other editor because an editor is highly subjective and a highly customization one is even more subjective. See if you like the core concepts of it and if you do give it a try, then wonder about customizing and extending it to better suite your needs, it takes time but eventually you get an editor that was custom made by you for you.

I have a file, which I read into memory. I find a particular string in the file I need to replace. How would you go about doing this?

What I'm doing is:

-find where string1 terminates
-rewind to where string1 begins
-copy the memory from before string1 starts to another buffer, x
-append my string, string2
-set file pointer in file1 to where the string1 terminates
-read file1 into memory2
-append memory2 to x

Any proper design suggestions?

I am considering dropping out of college and starting to work in an IT trade.
Btw, I live in Germany.
While I recognized that I still love coding and want to work in IT, I was running from an assignment to a job, while doing another assignment, while jobbing and I just felt miserable.
It took 4 years inclusive a mental breakdown, depression and a couple months long sessions with my CS friends to recognize how far deep I went:
I gained a lot of weight, stopped working out, stopped eating regularily.
Rather, I mostly ate to emotionally cope.
And the financial situation of living under the rules of a very traditionalistic immigrant family since years took the toll on me.

I want to take a step back and work on myself and my passion. I need a routine.

I would be glad about some additional advice from you so I can draw a better picture of my situation.

Despite all my addons it still works exactly the same on every platform as long as I have git installed o nthat platform, and git runs on everything. When I move ot a new computer, I download my vim config, and run vim, vim fetches all the plugins I use and I'm not good to go, it works just like it does on the rest of my machines. Vim came stock even on my chromebook and it worked fine there, although I did have to recompile it with Python support for one of my unnecessary scripts but most platforms have that already.

That being said though stock Vim is very powerful and can do a lot of shit on its own, and you can still configure it to act exactly how you wish.
This is a boring but neat video on some common things people usually install plugins for that stock vim can do.

What are some good applications for linux to brainstorm medium/large projects before starting them? Any free mindmapping applications? I would like to become more structured planning the inheritance ect before going balls deep.

can anyone here hop over to sqt real quick and help me with my probably not stupid enough for sqt but not competent enough for this thread question thank... i have a feeling it will go unanswered

I took a test for an entry level C# job, where one of my tasks was to write a function, which, given the radius of a circle N and assuming center at (0,0) gets the number of lattice points inside of it. It was required to be no harder than O(n) and return -1 if the result was greater than 1,000,000,000:

public int Solution3(int N)
        {
            int sum = 0;
            for (int i = 1; i <= N; i++)
            {               
                sum += Convert.ToInt32(Math.Truncate((Math.Pow((N * N - i * i), 0.5d))));
                if (1 + 4 * N + 4 * sum > 1000000000)
                    return -1;
            }

            return 1 + 4 * N + 4 * sum;
        }

This was my solution. Can it be improved?

No, there's only the one way.

struct some_name {
    // Here, you just put things like normal variable declarations
    int a;
    float b;
    char *c;
};

struct some_name variable;
variable.a = 10;
variable.b = 0.5;
variable.c = "hello";
// Or more succinctly
struct some_name variable2 = {
    .a = 10,
    .b = 0.5,
    .c = "hello",
};

(((structs)))

>>61238431
>>61238482
You can also typedef it like with any other type if for some reason you want to or need to.

typedef struct LongStructTypeName {
    int a;
    float b;
    char *c;
} ShortStructTypeName;

struct LongStructTypeName x;
ShortStructTypeName y;

The only difference is that you don't have to specify that "LongStructTypeName" is a struct with the struct keyword to use it, you can also omit "LongStructTypeName" if you never intend to use the struct alias.

I should have clarified, I meant typedef structs. For example,

typedef struct{
    Node* Next;
    Node* Back;
    int Value;
}Node;

This won't compile

typedef struct{
    struct Node* Next;
    struct Node* Back;
    int Value;
}Node;

This won't compile either

typedef struct Node{
    struct Node* Next;
    struct Node* Back;
    int Value;
}Node;

Oh, but putting "Node" right after the "typedef struct" makes everything cool. I guess I'm just confused why the previous two methods make the compiler eat shit. I wish I understood why this is so particular. Has something to do with calling the Node structure inside but I don't want to just accept it as a random rule to follow.

What's you're essentially doing in the first 2 is this.

typdef struct {
    MadeUpType x;
} Node;

Notice how MadeUpType is not defined, when you give the struct an alias (which is essentially a typedef inside the struct namespace) it is now defined and thus it can embed itself inside, before it's defined it has no idea what a Node is. This should be valid as well.

typedef struct Node Node;
struct Node {
    struct Node* Next;
    struct Node* Back;
    int Value;
};

int main(void){
  Node x;
  return 0;
}

structs are just types, does this example explain it? If not, what's still confusing?

Breaking this down too
>typedef struct Node Node;
typdef type typealias;
typedef (struct Node) [Node];
where () is the type, [] is the alias you want to give to that type.

struct Node {...};
This defines what a (struct Node) is, like another form of a typedef, you can think of it like this

(struct Node) is of type: struct { Next, Back, Vale}
Kind of like how function signatures are and how you alias those, struct signatures are similar.

I think the thing that trips people up is that it's not just a single word but it's still a single type.

>>61238594
Remember that these are both types:

struct{
    Node* Next;
    Node* Back;
    int Value;
}

and

struct{
    struct Node* Next;
    struct Node* Back;
    int Value;
}

And remember that a typedef has the following form:

typedef ExistingType NewNameForType;

So in both examples, NewNameForType is Node, and ExistingType is the "struct {}" and everything inside it.

The problem with the first one is that the type to which you're trying to assign the name Node (the type "struct { ... }") has to already exist before the name Node will. But it can't, because you use the name Node in that type. That's what's called a circular typedef, and it's certainly conceivable that it could work, but C does not support it. Typedefs cannot refer to themselves, because that would require the typedef operation to actually build the type, but all it's capable of doing is assigning a name to a type which already exists.

The problem with the second example is that

struct{
    struct Node* Next;
    struct Node* Back;
    int Value;
}

and

struct Node

are two different types. Namely, the first one is self explanatory as long as struct Node exists, and the second one, struct Node itself, does NOT exist. You're not defining struct Node there, you're just defining an anonymous struct type and trying to typedef it the name Node.

The reason the third example works is because you are defining struct Node, and struct definitions, unlike typedefs, are allowed to be circular -- but the struct type has to be named for its definition to be circular, because otherwise there's no way to refer to the same struct type.

I think this is making sense. From what I can gather, 1 and 2 are a bit circular in logic. No structure called "Node" exists so the compiler doesn't know what to do with it even though it is inside the Node structure.

So here is where I also scratch my head:

typedef struct Node{
    struct Node* Next;
    struct Node* Back;
    int Value;
}Node;

Why does "Node" have to be defined twice? For example, if I did

typedef struct {
    struct Node* Next;
    struct Node* Back;
    int Value;
}Node;

or

typedef struct Node{
    struct Node* Next;
    struct Node* Back;
    int Value;
};

It won't compile either. I guess it just bugs me because defining it twice doesn't look very clean. Does anyone have any online recommendations as to some good C learning sources? I'm currently just skimming http://www.learn-c.org and I can tell there is a lot of shit that I'm being left out of.

>>61239085
It doesn't have to be defined twice, what you're doing is 2 different definitions, in your broken examples they're broken because you're asking to define 2 things with 1 definition.

broken 1 is equivalent to this:
typedef UndefinedType TypeAlias
^undefined type is undefined ans thus not valid to use, you can't alias something to nothing.
broken 2 is equivalent to this:
typedef DefineType
^ notice the missing alias

In the complete example you have a valid structure type (struct Node) which is assigned to an alias of just "Node" which remember is not the same as (struct Node), even though that's 2 words, it's 1 type, and once the typedef is complete "Node" just because an alias which you can think of like a define "Node" gets expanded to "struct Node", this is an oversimplification though, it has to do analyses on the types during compilation, it's not just string expansion.

The type is more like this (struct Node{...}) where the ... is the members, that whole thing is a type, like how function signatures include the types of the parameters but a function signature results in a single type.

Is ok to typedef structs, what is wrong is to typedef pointers.

>>61238554
>>61239247
I'm gonna elaborate again.

typedef struct StructAlias {
    int a;
    float b;
    char *c;
} TypeAlias;

Breaking down where () is a SINGLE type just like int, float, etc.

typedef (struct StructAlias {
    int a;
    float b;
    char *c;
}) TypeAlias;

That whole thing resolves down to a single type of "struct StructAlias" which is now a valid type, you can then alias that type like this
typdef struct StructAlias TypeAlias;
Remember it's a single type despite being 2 words. typdef (struct StructAlias) TypeAlias;
An alternate layout for that is this.

int main(void){
struct StructAlias {
    int a;
    float b;
    char *c;
};
typedef struct StructAlias TypeAlias;

struct StructAlias x;
TypeAlias y;
  
  return 0;
}

The reason it's usually the same name is probably for ubiquity of the long form, it usually doesn't make sense to have 2 names for the same structure when instead you could just have 1 word for both forms. Although I think historically they had to be different for a technical colliding reason, that's no longer the case though so don't worry about that.
