its the return statement that makes your loop only run once.

I'm rusty...
i = 5;
return i++;
i = 5;
return ++i;
In which case will it return 5, and in which will it return 6?

5 for the first, 6 for the second.

You and me both. When I went through school I bombed all those quizzes. But after all that schooling and practice and a year or so of industry work and you will have a hawks eye for code.

Hehe. Trust me, I'm doing tons of practice in the years ahead. In fact, I'm experimenting with making a tile-based game app at this very moment.

I really prefer +=. In fact I actually had a stylistic guide in a class once that would not allow you to use the ++ operator. The autochecker for assignments would throw an error until you changed it.

I think I learned more in this thread than I did in class... (why was there always some gsl/pl/gstl on when I'm in school?)

So now instead of
void func(int i) { }
int i = 42;
func(i++);
you always write
void func(int i) { }
int i = 42;
int t;
func((t = i, i += 1, t));
Yes, that's an assignment too, even though there is no = sign in the function call.
Granted, the sequence
vector<int> v(10, 0);
int i = 0;
v[i] = i++; Can resolve to pretty much anything your compiler wants it to, but is that a reason to avoid ++?
My C++ got really rusty from all that C# lately, geez. Had to look up all of this to make sure I'm not making mistakes...

You're doing it wrong if you are using the '+' symbol at all.
#include <iostream>
using namespace std;
int add(int x, int y) {
int a, b;
do {
a = x & y;
b = x ^ y;
x = a << 1;
y = b;
}while(a);
return b;
}
int main()
{
cout << add(2,6);
system("pause");
return 0;
}

wait... what are you trying to do in this code? I got lost at the beginning and then the code just changed into so many different formats that I was like  then  and finally,

Write it out on paper. These are bitwise operators. It means you manipulate the bits.Convert 2 and 6 in the binary format from decimal and then follow it along.

Oh binary! I haven't worked with those for a whole year. That explains it. Thanks, I think I understand it now

I'm going to have to fix this.
int add(int x, int y) ??<
int a, b;
do <%
a = x bitand y;
b = x ??' y;
x = a << 1;
y = b;
??> while(a);
return b;
%>
And while we're at it, we should create a wrapper class for int, maybe called inT, and only use that instead of the built in type. Then we overload the +, += and ++ operators for great success.

Incidentally, I'm also working on a tile based game at this very moment. Using LÖVE, which is nice, because Lua is a pretty cool language and I don't have to write all the boilerplate code or all the low level opengl stuff just to do 2d rendering. Just found someone's component based entity system and I'm working on building off that.

Huh. I don't believe I've heard of Lua before. I may check it out sometime in the distant future.

Lua is the scripting language blizzard uses to create the UI in WoW. Its one of the most popular along with python. They are really useful tl know.
