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.

Rating D: 0
Assigned grade: A
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.

Student submission:
#include<iostream>
using namespace std;
int main() {
	int n, i;
	cin >>n;
	for(; n>=1; n=n/10) {
	i = n%10;
	cout << i;
	 }
	if ( n==i) cout << "1";
	else cout << "0"; 
	}

Grading criterion: Overall program correctness
Rating A: "Common requirements  of a Program are correct - i.e.
 
- header (includes, using namespace, etc)
- main syntax
- variables declaration
- overall syntax"
