this has been answered before: how clear console screen in c?

basically, it's not cross-platform. if you're using ubuntu, line should work:

printf("\e[1;1h\e[2j"); 

when test is:

#include <stdio.h>  int main(int argc, char *argv[]) {     printf("\e[1;1h\e[2j");     printf("3\n");     sleep(1);      printf("\e[1;1h\e[2j");     printf("2\n");     sleep(1);      printf("\e[1;1h\e[2j");     printf("1\n");     sleep(1);      printf("\e[1;1h\e[2j");     printf("0\n");      return 0; }
