Is there any way to change the color of the cout statements, or cin for that matter?

Do you mean you want to display text in colors? If so, read this recent question:

A simple and relatively portable way is using ansi escape sequences. On windows you might need to install ansi.sys driver

cout << "\033[31;43mHello world\n"; // red on yellow

Good answers have been given above, but for a more VC++ based solution, this is a fair example:

#include  <stdio.h>
#include  <windows.h>

void ChangeColour(WORD theColour)
{
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);  // Get handle to standard output
    SetConsoleTextAttribute(hConsole,theColour);  // set the text attribute of the previous handle
}

int main()
{
    ChangeColour(FOREGROUND_BLUE);      // Set the foreground colour to be blue
    printf("This text is blue\n");      
    ChangeColour(FOREGROUND_RED);     // Set the foreground colour to be blue
    printf("This text is red\n");    
    ChangeColour( FOREGROUND_BLUE | BACKGROUND_RED);  // Set the foreground colour to be blue, the background to be red
    printf("This is blue text on a red background\n");  

    return  0;
}

jaime_olivares : As I am not running any unix based systems, I cannot do the ansi stuff...

__init__: also ansi.sys will make my program non-compatible with those with no ansi.sys, and im not thinking of porting, so why go throguh the trouble..

system("color //hex"); changes the overall color of the prompt.

also (FORE)(BACK)GROUND_INTENSITY make the colors brighter, exactly what I need..

anyone know how to make orange??, I tried to no success.

You can actually mix the colors, eg

ChangeColour( FOREGROUND_BLUE | FOREGROUND_RED); // Purple

but unfortunately FOREGROUND_YELLOW does not exist.

I dont think there is a way to make orange hence.

Nope, tried but could not figure it.  You may be able to if you spend enough time playing about, but even with

WORD COLOR_YELLOW = (FOREGROUND_RED | FOREGROUND_GREEN);

    ChangeColour((FOREGROUND_RED) | COLOR_YELLOW);      // Set the foreground colour to be blue
    printf("This text is Orange (?)\n");  

the text still comes out just the same as COLOR_YELLOW...
