how to get percentage

this one should compile cleanly with gcc.

Code:

$ cat print-restore.c
#include <stdio.h>
#include <ctype.h>
#include <errno.h>
#include <stdarg.h>
#include <stdio.h>
#include <stdlib.h>

#include <string.h>
#include <math.h>
#include <sys/stat.h>
#include <time.h>
#include <getopt.h>
#include <unistd.h>
