int ret = sscanf(input, "%d%f%9s%2d%f%*d %3[0-9]%2lc",
                     &i, &x, str1, &j, &y, str2, warr);
                     
/* sprintf example */
#include <stdio.h>

int main ()
{
  char buffer [50];
  int n, a=5, b=3;
  n=sprintf (buffer, "%d plus %d is %d", a, b, a+b);
  printf ("[%s] is a string %d chars long\n",buffer,n);
  return 0;
