#include <stdio.h>



int main() {

   char s1[] = "advise";     

   char s2[] = "advice";



   int n = 0;

   unsigned short flag = 1;



   while (s1[n] != '\0') {

      if(s1[n] != s2[n]) {

         flag = 0;

         break;

      }

      n++;

   }



   if(flag == 1) {

      printf("%s and %s are identical\n", s1, s2);

   } else {

      printf("%s and %s are NOT identical\n", s1, s2);
