Since I'm great enough at C++ to create console applications that actually don't suck, and yet I'm dumb enough to barely comprehend Windows programming, can anyone give me ideas for a console application that I should make?
You could try your hand at SFML and create a basic game. If you go through the tutorials on their site (don't just download the examples, actually type out the code yourself) you should learn enough to make a tic-tac-toe game.
Do [url]http://projecteuler.net[/url] problems
Slightly offtopic, but I did not want to start a new thread.
I just looked at the "projecteuler" link that gilly posted and I had a go at problem 1.
And for some reason my code is outputting the numbers that don't work instead of the ones that work.
It is probably really simple and I am probably going to feel like an idiot after finding out what is wrong, but here is the code:
[code] int counter = 0;
while(counter < 10)
{
if((counter % 3) || (counter % 5) == 1)
{
cout << counter << "\n";
}
counter++;
}
[/code]
The output is:
0
1
2
4
5
7
8
I would be grateful if anyone could tell me what is wrong.

You can't check both conditions with || like that, you need to do if (something == blah || someElse == blah)
Aha :D
It worked, thanks.

That's one thing that always pisses me off about C++ but I have to live with.
Is there any technical reason this isn't allowed in C++? Because it would really make a lot of if statements out there shorther...
It's more logical.

[cpp]
#define either(x,a,b) (x == a || x == b)
int foo = 1;
if either(foo, 1, 2)
{
// true
}
[/cpp]
Or this:
[cpp]#include <cstddef>
//note: only works for stack-allocated arrays; use std::vector otherwise, pass a count-variable or use boost::array/C++0x std::array
template<typename T> bool either(const T vars[], const T value){
const std::size_t count = sizeof(vars)/sizeof(T);
for(std::size_t i = 0; i < count; ++i)
if(vars[i] == value) return true;
return false;
}[/cpp]
The C++0x/Boost-way:
[cpp]#include <cstddef>
#include <array> //boost/array.hpp for Boost
//boost::array for Boost
template<typename T, std::size_t Size> bool either(const std::array<T, Size> &vars, const T &value){
for(std::size_t i = 0; i < Size; ++i)
if(vars[i] == value) return true;
return false;
}[/cpp]

Yeah, it doesn't make sense.
== tells you if 2 things are the same. Exactly 2 things, no more, no less.
|| tells you if either of 2 conditions is true. Either of exactly 2 conditions, no more, no less.
if (a || b == c) says "if either the condition 'a' or the condition 'b == c' is true, then execute the body of this if statement"
Yes, numbers in C++ can be implicitly converted into booleans - anything non-zero is true, 0 is false.

Reminds me of this thing I found a while back:
[URL="http://xkcd.com/91/"]http://xkcd.com/91/ - Cartoon: Text-based Counter-Strike[/URL]
I'm pretty sure that's where I got that from. I had the idea stuck in my head for a long time.

Make it a function.

I tried to make a tetris one but It was to complicated
*CLIP--that was stupid*
