sprintf() is what you're looking for.
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
int x = 322;
char c[4];
sprintf(c, "%d", x);
printf("%s", c);
return 0;
}

>sprintf() is what you're looking for.
Though sprintf is a prime suspect for buffer overflow. libc supports snprintf, and the advantage of safety outweighs the disadvantage of being non-portable (though C99 does support it). |
