So I've been using visual studio 2013 and 2015 community for quite some time now for C++ and some python. And now out of no where my console window doesn't stay open.

I've been using the ctrl F5 command to get the console window to remain open after debugging by going into my project's properties > linker > system > subsystem > Console (/SUBSYSTEM:CONSOLE). I've been doing this for years and it's worked perfectly until today.

Anyone have the same issue in visual studio 2015 or know any fixes around it? I've done some googling and cant seem to find anything specific for 2015 issues regarding this. I would rather not have to use breakpoints at the end of my source code every time I want to run my shit, nor do I want to put in shitty code "cin.get()" or even worse "system("pause)"

Perhaps a better solution for an IDE would be to redirect the stdout of the child program to some window of the IDE, rather than letting Windows spawn a console window for it, and killing the process afterwards.

>>52877021

If you are writing a console program, it is only natural that you should launch it from the console.

wew, knocked out like 4 major features today
but it also made me realize how shitty the system for waiting for events is. i might add hooks to specific events that occur automatically, sorta like
Api.Hook.when_upload event_handler_function
to make it easier to bind onto events, because it would be really difficult to write some of the commands I was gonna add. I really want to add in my /jukebox but it feels like it'll be a week at least before all the requirements for that are in place (binding onto upload events/binding onto replies from specific users, different handling of incoming vs. outgoing data, support for more than just 2 audio formats, etc.)

Say an array is passed as an argument for a routine. After the save function, the argument is available as a formal parameter in an i (in) register. From there, how can I update the parameter? I know the store instruction is required, but I don't know whether to use the frame pointer (%fp) or an in register (such as (%i1) is what I should be storing the new value into, and just trying stuff out isn't really helping because gdb doesn't say much if something is incorrect yet can compile.

double clicking is directly executing the file. when you do `java -jar` that doesn't directly executes it, but lets the JVM execute it. nothing is "wrong" with it. if you want to make it double-clickable then you can create a bat file that runs that command and then create the shortcut to that.

well you'd have to package all those files together. the best method would be with an installer that either sets jars to automatically open with the correct program (see: http://stackoverflow.com/questions/8511063/how-to-run-jar-file-by-double-click-on-windows-7-64) or one that installs the shortcut wherever and then puts the jar/bat file in your program files. that's probably not an options so maybe just distribute with a zip?

I have numerous C# classes that look more or less like this:

public Dictionary<U, V> Bar { get; set; } = new Dictionary<U, V>();

}


Instances of these are kept in numerous Dictionaries, where the value is the object and the key is variously the ID or Name of the object. These Dictionaries are serialized and deserialized with Json.NET for persistence.

Because ID and Name are used to lookup the object, I want to make them immutable. What is the best way to do that without breaking deserialization?

In the past, we often relied on concurrent functionality to sustain interactive systems - in modern times, however, this parallelism is frowned upon due to its lack of sustainability. However, just because modularity works modularly doesn't mean we can assume that functionality will be functional. Modular language design must promote sustainable modularity for the sake of interactive interactivity. However, just because parallelism works concurrently doesn't mean we can assume that sustainability will be concurrent. As a result, structure may not provide the versatile modularity its proponents had hoped.

If one learns c properly ie work on some medium sized projects, understand learn and build some dynamic data structures, and has a good grasp of memory management then the transition to OOP takes maybe a day of reading. Theres nothing wrong with having a good foundation of industry standard syntax without it being fucked up by higher level abstract concepts that beginner programmers don't even need to have access to.
>>
>>52879222
Yes, of course. The caller provides a buffer, which your docs will say "must be able to store at least FOO_MAX characters". Or, the caller may provide a buffer alongside a length field. Return an error status if the length indicated is not long enough to store the result. Alternately, the caller may pass NULL for the buffer, and the function will malloc and return buffer of the appropriate size, which the caller is then responsible for freeing. Another option is to, rather than return a newly allocated buffer when the given buffer is NULL, instead return the size of the buffer that will be required to store the output data. Yet another option is to accept the length field as a pointer-to-length-field (to use as an input/output parameter) and use the return value to indicate an error or success code. Fill in the length field as an output parameter indicating the number of bytes in the buffer that were actually used - or fill it in with the number of bytes required if the buffer pointer is NULL.

The best option is just to not even use fucking C and have the function return a String or Data object, which the caller is not really responsible for at all, because it's managed by the runtime's GC or ARC.

> Does signed and unsigned multiplication have to be treated differently with two's complement?
If the result is truncated (wrapped) to the size of the inputs, then no. If the result isn't truncated (meaning that it's twice the size of the inputs), then yes.

In two's complement, -n is represented as k-n where k=2^N.
(k-a)*b = k*b-a*b. Which is equal to -a*b if the result is taken modulo k, but not if it's modulo k^2.

On x86, multiplies aren't truncated: the result takes up two registers, one for the high word and one for the low word. So there are distinct signed and unsigned multiply instructions. Architectures where the high word is discarded have a single multiply instruction for either signed or unsigned.

updateFoo:
save %sp, -96, %sp ! basically makes the params available in the in registers

ld [%i0], %l0 ! maps bar[0] to %l0
mov %i1, %l1 ! puts updateNumber in %l1

stb %l1, [%i0] ! tries to store contents of %l1 in bar[0]

Let's dispel once and for all this fiction that Barack Obama doesn't know what he is doing. He knows exactly what he's doing; he's undergoing a systematic effort to change this country and make America more like the rest of the world. If I'm elected we'll embrace what makes America the greatest country in the world.

Okay Joe, you've had extensive training on how to add two numbers together, so we need you to write a function that does just that.
We're using python.
def add(a, b):
return a + b;


Joe, you're code sometimes works and sometimes doesn't. You're incompetent. Let me give you examples of where it doesn't work.
add("one", 4);
add([1, 2, 3], 6);
add("cat", "fog");


What did Joe do wrong /dpg/?

Should he check the input types of the variables and throw exceptions?
But then the only way to know if the code works is to actually run it and see if it throws an exception.

Should he teach the entire team on how to add two numbers together just so they learn how to use the function correctly?
But then the project will never be finished.

Should he do some clever "to number" conversions before adding the numbers together?
But then the add function becomes a clusterfuck and inconsistent.

so i'm just starting to learn C through the C Programming Language, and a reoccurring thing i don't understand is the use of EOF in chapter 1.

it's never written that i should #define EOF in the code in the books, but unless i do i of course get an error.
should i just add #define EOF even though there's no mention of writing it in the book, or am i missing something?
>>
>>52881199

>>52881213

It's defined inside <stdio.h>, which you should be including if you're using any of the I/O functions.

Oh, well I'm trying to figure out why my store operations are working for one of my assembly files but not the other, and that's the only notable difference I see in how their drivers are calling them.

no, you are not correct, as array memory is reserved only once.
>>
>>52881313
C has a thing called pointer decay, where an array label will convert into a pointer to the first element when used.
You can't pass an array to a function, as it will always just decay into a pointer.

Hey lads,
I make mods for Crusader Kings 2, but I keep have to manually renumber a lot of things.

Would is be possible for any of you to write a small script (Python, or whatever), that opens the file, and changes every number to +N (whereas N is variable)?
I never got any further then Hello World, and English is not my native language.

Every number starts on a new line and ends with a =, like so:
>1=
>{
>something
>}
>2=
etcetera.

Thanks in advance!
>>
>>52881326
Easy
.global _start

str:
.ascii "hello, world!\n"
.set str_len, .-str

.section .text
_start:
movq $1, %rax # write
movq $1, %rdi # stdout
movq $str, %rsi
movq $str_len, %rdx
syscall

movq $60, %rax # exit
xorq %rdi, %rdi # RETURN_SUCCESS
syscall

Add N to each number, so

>100=
>101=
+N, whereas N is variable, in this case 30
>130=
>131=

Working on a page in ASP.NET, getting some error that "spec0 blah blah must be placed within a form tag with runat=server".

I've of course made sure that <form> has runat="server and I even tried adding so that the created textbox has runat="server" too. Anyway, the basic function of the code is to add a textbox when clicking the button and increasing the number of the id with each textbox. Adding the first box, which is named spec0, goes smoothly but clicking again produces the error. Since it says "spec0", I am suspecting that the error comes from me fucking up the C# code.

And yes, I'm fucking retarded and new to programming, most of the code you see here comes from searching and adapting the code to the project.

protected int NumberOfControls
{
get { return (int)ViewState["NumControls"]; }
set { ViewState["NumControls"] = value; }
}

protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
//Initiate the counter of dynamically added controls
this.NumberOfControls = 0;
else
//Controls must be repeatedly be created on postback
this.createControls();
}

private void createControls()
{
int count = this.NumberOfControls;

for (int i = 0; i < count; i++)
{
TextBox tx = new TextBox();
tx.ID = "spec" + i.ToString();
//Add the Controls to the container of your choice
Page.Controls.Add(tx);
}
}


protected void addnewtext_Click(object sender, EventArgs e)
{

TextBox tb = new TextBox();
tb.ID = "spec" + NumberOfControls.ToString();
tb.CssClass = "form-control" + " " + "span6";
PHbox.Controls.Add(tb);
tb.Attributes.Add("runat", "server");
this.NumberOfControls++;
}
