Thats quite an advanced topic, first learn the basics of C, ie, input /output / functions
before you move on to the more complex topics.
This colde changes the color of cosole text, but for inserting a bitmap or icon in C, it is somthing I have never learnt.
Code:
HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
WORD wOldColorAttrs;
CONSOLE_SCREEN_BUFFER_INFO csbiInfo;
GetConsoleScreenBufferInfo(h, &csbiInfo);
wOldColorAttrs = csbiInfo.wAttributes;
SetConsoleTextAttribute ( h, FOREGROUND_BLUE | FOREGROUND_INTENSITY );
