#include<iostream>
using namespace std;
int main() {
int n,m,j=1;
cin>>n;
m=n;
int i,p=1;
while(i>=0)

if(m==0) break;
 j++;}
int rem,quot;
rem=n%10;
for(int k=1;k<j;k++)
{p=p*10;}
quot=n/p;
if(quot==rem) cout<<"1" ;
else cout<<"0";
}

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.
