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,a,k,j=0,p=1,m,l,d,e,f=1;
cin>>n;
if(n>0){
while(k != 0)
   {k=n%10;
    a=n/10;
    n=a;
    if(k>0)
    {j=j+1;}
            }
if(j%2 == 0){
for(int i=1;i<=j/2;i++)
   { m=10^p;
     l=10^j-1;
    if(n/l%10 == n%m)
   { j -= 1;
     p += 1;}
        }
cout<<"1";}
else cout<<"0";

else if(j%2 == 1){
for(int i=1;i<=(j-1)/2;i++)
   { d=10^f;
     e=10^j-1;
    if(n/e%10 == n%d)
   { j -= 1;
     p += 1;}
   }
