Thread: Validation of password please help

program should validate the input data (password) based on the following rules: The password length should have a minimum length of 6 and maximum of 15 characters Some characters aren’t allowed in the password including “space” and “-”. If user includesthese two characters in the input, the program should display “invalid password”.

Code:

int main()
{
  char password[15];
  int lenght;

  int str;
  printf("Please enter the password:\n");
  printf("note:no space or - in password\n");
  printf("note:min password lenght =6 and max password lenght =15\n");
  fgets(password, 15, stdin);
  int i = strlen(password);

  if (i < 5 || i > 14) {
    printf("please check the lenght rules ");

  }

  else if (i > 0) {
    for (int j = 0; j <= i; j++) {
      password[j] == ' ';
      password[j] == '-';

    }
    printf("No space is allowed or any hypens - ,please try again");
  } else

    printf("registered");

}
