Check out the functions [URL="http://www.cplusplus.com/reference/clibrary/cstdlib/rand/"]rand()[/URL] and [URL="http://www.cplusplus.com/reference/clibrary/cstdlib/srand/"]srand()[/URL] for randomization. You can use those functions to generate yourself some RGB values and then change the values of the text color to the generated values.

What jonsca said is true, you cannot use graphics.h in Visual C++ or other IDE except Turbo C++. What you can do is, use that old WinBGIm library that jonsca mentioned along with Dev-C++(MinGw). Here is a tutorial on this topic: [URL="http://onecore.net/dev-c-graphics.htm"]link[/URL]. It has pretty much the same functionality as …

Hi! I'm writing the mergesort algorithm, theoretically everything is fine in it but when the function gets to call itself the program crashes. I belive that I'm doing something worng when I pass the vector<int> as a parameter to the function. [B]procedure mergesort(T[1 .. n]) if n is small then …
