Most terminals support ANSI escape codes. You can use a J (with parameter 2) to clear the screen and an H (with parameters 1,1) to reset the cursor to the top-left:

printf("\033[2J\033[1;1H");

Alternatively, a more portable solution would be to use a library such as ncurses, which abstracts away the terminal-specific details.
