C++ Program to Check Whether a Number is Palindrome or Not

To understand C++ program to check whether a number is palindrome or not, you should know about - C++ looping.

Palindrome number in C++

If the reversed pattern of the digits of a number is equal to the original number, then the number is called palindrome number.

Note : Palindrome number must be a positive integer

C++ Program to Check Whether a Number is Palindrome or Not

#include<iostream>

using namespace std;

int main()

{

    int n,rem,rev=0,t;

    cout<<"Enter a number : ";

    cin>>n;

    t=n;

    while(n!=0)

    {

        rem=n%10;

        rev=rev*10+rem;

        n=n/10;

    }

    if(t==rev)

        cout<<endl<<t<<" is a palindrome number";

    else

        cout<<endl<<t<<" is not a palindrome number";

    return 0;

}

OUTPUT 1:

Enter a number : 45254

45254 is a palindrome number

OUTPUT 2:

Enter a number : 487

487 is not a palindrome number
