Thread: Errors When I Color

In this program I am trying to color the answers. If the answer is correct it is green and if incorrect it is colored red. But it wont color the individual letters. Il'l mark the area with the important stuff.

Yes the code is long but i marked the part that needs to be looked at.

FYI: There are no actual errors, it runs fine.

If you hadnt noticed, the source file is under this post, so you can run it yourself. It will make more sence if you do.

Code:

#include <iostream.h>
#include <iomanip.h>
#include "apmatrix.h"
#include "apvector.h"
#include <stdlib.h.>
#include <windows.h>

//Easy Coloring Of Words/Letters
#define Color_White SetConsoleTextAttribute(stdOut, FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_RED);
#define Color_Red	SetConsoleTextAttribute(stdOut, FOREGROUND_RED | FOREGROUND_INTENSITY);
#define Color_Green SetConsoleTextAttribute(stdOut, FOREGROUND_GREEN | FOREGROUND_INTENSITY);

HANDLE stdOut = GetStdHandle(STD_OUTPUT_HANDLE);
