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.

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, b, c, s,n;
cin >> n;
 s=0, a=n, b=n, c=0;
while(a!=0){
c=a%10;
s=s*10+c;
a=a/10;
}
if(b==s)
cout << "1";

else
cout << "0";
