Write a program in C to compare two strings without using string library functions.

#include <stdio.h>

void main()

{

   char str1[100],str2[100];

   int i;

   printf(“Enter the first string:\n”);

   fgets(str1, sizeof str1, stdin);

   printf(“Enter the second string:\n”);

   fgets(str2, sizeof str2, stdin);

   for(i=0;str1[i]!=’\0′ || str2[i]!=’\0′;i++)

   {

      if(str1[i]!=str2[i])

      {

         printf(“Given strings are not identical\n”);

         return;

      }

   }

   printf(“Given strings are identical\n”);

}

Output:

Enter the first string:
