Explanation:- Reverse a string using pointers is very likely as Stack program it also follow the same rule of Stack FILO (First In Last Out) in Reverse a string using pointers we are doing same when we are taking input from user at same time we are calculating the length of a String and with the help of length one by one we are transferring the character one by one from one string to another and until length is not become zero in while loop we put the same condition.

    char *strPtr = str;
    char *revPtr = revStr;

    int len = -1;

    printf("Enter The String Without Space:\n\n");
    scanf("%s",str);

    while(*strPtr)
  {
      strPtr++;
      len++;
    }

    while (len >= 0)
  {
      strPtr--;
      *revPtr = *strPtr;
      revPtr++;
      --len;
    }

    *revPtr='\0';
    printf("\n\nReverse String Is \n\n%s",revStr);
    return 0;
}

Output:-
