Thanks, but what about for Linux?

I also couldn't find any references or docs online for GetAKeySyncState(), and when I try to compile (after including windows.h) on my Windows machine I get

How would one listen for keyboard input, without causing the program to pause waiting for the input? For instance say you have something like
float num = 0;
bool runloop = true;
for(int i=0;...

I have LAPACK and am having problems trying to compile while linking to it with g++ (MinGW and MinGW 64, have and tried both) using the following command:
g++ main.cpp -I"C:\Program Files...

That works. So I guess #ifdef can't do and/or, you have to use defined. Thanks.

I'm using MinGW. I checked and WIN32 and _WIN32 both evaluate as true for me.

So this syntax is actually OK? Because the following gives me "warning: extra tokens at end of #ifdef directive"...

Is it possible to use #ifdef with Boolean AND and OR? For instance something like
#ifdef WIN32 || WIN64
cout << "This is Windows." << endl;
#endif
The above doesn't give a compiler error for me,...

It was a 32 bit/64 bit issue. I had a ton of problems updating Visual Studio (got some real weird errors...

(edit: whoops, you posted as I was reading that vcvarsall stuff :) I'll check out that link)

Thanks. The version I have is the Professional Edition. How do I use the 64-bit compiler? Do I change a...

I'm having a lot of trouble finding enough RAM for a program I'm writing on Vista 64 Ultimate system, even though the system has 8GB RAM and only 2GB is used.

I tried to see how many 10 million...

Sounds like a good idea, but unfortunately I'm not familiar with threading.

Thanks a lot Ancient Dragon, that solution works :)

I have a class that has functions which use <stdio.h> and <stdarg.h> to take in indefinite arguments, and one of the member functions taking in filenames. There's another function (call it the "do"...

Thanks, I made those changes and it worked :)

I also tried using va_copy, like below, and that also worked. Don't know if one method is more proper than the other:
void battleShip(int n,...){
//...

I have another question regarding this.

I didn't realize that you could pass the first argument as an int regardless of what the other arguments are. But, how does one pass indefinite arguments...

Is there a coding reason why it would be preferable to use "const char *" instead of just "char *"?

Odd, when I run your code it outputs just "One!.." "Two!.." "Three!..", without the "Air-raid...

Thank you :)

Just to note, it seems you have to manually use the first argument.
#include <stdarg.h>
#include <iostream>
using namespace std;

void battleShip(const char* what,...)
{
...

Thanks. How does one access the C string arguments then? For example how would one get 'void test_args(int arg_count, char* cur_s, ...){}' to display each C string with 'test_args(3, "hello", " ",...

How does one do this with strings or other types than ints?

For instance something like,#include <iostream>
#include <stdio.h>
#include <stdarg.h>

using namespace std;

void...

Thank you very much, I didn't realize it would be that complicated to read with fgetc(). You're right, fread() is much better :)

Can getc()/putc()/fgetc()/fputc() be used to read/write chars and floats rather than ints only from binary files? If so, how?

Thanks, that works.

So you need the & in int& operator[]... in order to be able to alter, but not to access, as you can only alter if it returns a reference; took me a bit to understand that.

The vector class provides access and altering uses brackets, e.g. v[5]. How can I make a class that can do the same? e.g. given Class Test object t, t[5]=...

I believe indefinite arguments can be defined with '...', but then how do you access them? For instance for the following function:
int test(int n, ...){
return n;
}

Thank you, I realized my mistake - I had been doing:
int combined = i << 8 | j;

Instead of:
int combined = i << 24 | j;

williamhemswort, I am using Linux :)

A related question - for int,...

I'm trying the following code to combine ints, and then get the original ints back:
#include <iostream>

using namespace std;

int getleft(int n){
return (n >> 24);
}

int getright(int n){

Another question: what is the purpose of the ios::binary flag? When I try it, the output and input is always binary, even if the flag is omitted and other flags like ios::app are used instead.

Yes that worked, thanks :)

I'm trying to use fstreams to read and write binary data to a file with the following code:
#include <fstream>
#include <iostream>
using namespace std;

int main(){
ofstream out("test.data",...

Thank you, so this is just a special shorthand for char arrays.

Is there any programming reason why I always see function definitions with arguments like this:
char getchar(char *arr){
Instead...

Ah I see, yes that works.

However I still don't understand the use of the * operator in the context of declaring arrays.

I'm confused about the use of the dereference operator in the declaring of char arrays.

I think I understand that the dereference operator is used to dereference memory addresses to their values,...

Are there any functions to calculate, or common techniques to estimate, how much memory a C++ script is consuming at a given moment/place in the code? Maybe some built-in function that keeps track of...

Turns out that the Makefile had some incorrect settings, in terms of where mysql is located on my server:

I'm trying out MySQLWrapped, but am having a strange problem that I can't figure out. After downloading mysqlwrapped-1.6.tar.gz, running 'make' and mimicing the MySQLWrapped example...

Is there any difference between regular expressions in C++ and in PHP/Perl? Or can one use the same regular expressions in C++ as in PHP?

Thank you.

Do others have any suggestions or tips?

I'm a C++ beginner. What's an easy to use (in terms of both installation and use in code) library for using MySQL in C++? Is there one that's a lot more commonly used than others? Note that I'm using...
