Colors

i want to add font color and Back ground color and image
Is this in console or a windows application? What platform?
If it's console you can use the functions from dos.h
textbackground(specify color here e.g WHITE);
textcolor(specify color here e.g BLUE);
@nasser

Staying on the idea that you're using the console, and not a window program, here is a way to use colors. Not many compilers can use dos.h as I believe it's a little outdated. I could be wrong, but I don't see many programs using it.

Alternatively, you can also use system("color 2E"); //2E is the code of the color.I think you'll have to include windows.h for this.
@voidmainvoid

The only problem with using system("color ##");, is that ALL the text on screen changes, not just the current background and colored text.
Also, system() is bad practice. See:
