    printf("Enter  string1: ");

    gets(s2);
    if(strlen(s1)==strlen(s2))
    {

        {
        	if(s1[i]==s2[i])
        	 c++;
 	    }
 	    if(c==i)
          printf("strings are equal");
        else
          printf("strings are not equal");
    }
    else
     printf("strings are not equal");
