Question

Pls may i know why I don’t get the output
#include <iostream>
using namespace std;

int main() {
int n,n1,n2=n,rev=0;
cout<<"Enter any number";
cin>>n;
while(n)
{
n1=n%10;
rev=rev*10+n1;
n=n%10;
}
if(n2==rev)
{
cout<<"num is palindrome";}
else
{
cout<<"num is not palindrome";}

return 0;
}

Answer 1

1. Change n=n%10 to n=n/10.
Otherwise, the value of n never changes and the code is stuck in an infinite loop.

2. Declare n2=n after cin>>n;
Otherwise, an error will be thrown for the n2 variable since n hasn't been initialised yet.

Answer 2

error in code, while loop runs infinitely if the number n does not end at 0
