putimage function outputs a bit image onto the screen.

Declaration:- void putimage(int left, int top, void *ptr, int op);

putimage puts the bit image previously saved with getimage back onto the screen, with the upper left corner of the image placed at (left, top). ptr points to the area in memory where the source image is stored. The op argument specifies a operator that controls how the color for each destination pixel on screen is computed, based on pixel already on screen and the corresponding source pixel in memory.

c smiling face animation

This animation using c draws a smiling face which appears at random position on screen. See output below the code, it will help you in understanding the code easily.
