Problem: Write a C++ program that takes a positive integer as input from the user and determines whether or not it is a palindrome. The program should print 1 if the number is a palindrome, otherwise print 0. The input number should be greater than 0 and should not begin with 0. The program should not use arrays.

- variables declaration
- overall syntax"
Rating B: Problems are present in the code(eg: printing unnecessary strings, missing semicolons & braces, wrong/missing declarations, wrong header files)
