c 2b 2b change console color

1WORD color = 0x0F; // White
2SetConsoleTextAttribute( GetStdHandle(STD_OUTPUT_HANDLE), FOREGROUND_RED);
3cout << "Hello World" << endl;
4SetConsoleTextAttribute( GetStdHandle(STD_OUTPUT_HANDLE), color);
5// The farbcodes are the same as they, when you type "color help" in the windows 
6// cmd in. First the number, then the letter (here the output of the cmd):
7/*  0 = Black       8 = Gray
8    1 = Blue        9 = Light Blue
9    2 = Green       A = Light Green
10    3 = Aqua        B = Light Aqua
11    4 = Red         C = Light Red
12    5 = Purple      D = Light Purple
13    6 = Yellow      E = Light Yellow
14    7 = Light Gray  F = White
15    */
16// So, to get the output white again, you have the set the color to:
17// 0x + 0 (Black Background) + F (White Foreground)
18// This works on every OS!
