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 B: Comparison not done or wrongly done.
Rating C: 0
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 <simplecpp>

main_program{
	
	int a;cin >> a;int i;int s=0;const int y = a;


	while(a%10!=0){i=a%10;a=a/10;s=s*10+i;}


	if(s==y){cout << "1";}
	else if (a!=s){cout << "0";}

}
