C program to compare two strings using pointers

Write a C program to compare two strings using pointers.

  #include <stdio.h>
  #include <string.h>

  int main() {
        char str1[256], str2[256];
        int i, flag = 0;

        /* get the first string from the user */
        printf("Enter your first input string:");
        fgets(str1, 256, stdin);
        str1[strlen(str1) - 1] = '\0';

        /* get the second string from the user */
        printf("Enter your second input string:");
        fgets(str2, 256, stdin);
        str2[strlen(str2) - 1] = '\0';

        /* checks whether given two strings are same or not */
        for (i = 0; i <= strlen(str1); i++) {
                if (str1[i] != str2[i]) {
                        flag = 1;
                        break;
                }
        }

        /* print the output */
        if (flag) {
                printf("Given two strings are not same\n");
        } else {
                printf("Given two strings are same\n");
        }

        return 0;
  }

  Output:

  jp@jp-VirtualBox:~/$ ./a.out
  Enter your first input string:Micheal Jackson
  Enter your second input string:Micheal Jack
  Given two strings are not same
