C++ Palindrome Check for a given Number
In this tutorial, we will learn how to check if the given Number is Palindrome or not, in the C++ programming language.
Condition for a Number to be Palindrome:
A number which is equal to its reverse.
Steps to check if the Number is Palindrome:
Compute the reverse of the given number.
If the number is equal to its reverse, it is Palindrome else it is not.
using namespace std;
//Returns true if the given number is a Palindrome number
bool isPalindrome(int n)
int reverse = 0; //to store the reverse of the given number
int remainder = 0;
int n1 = n; //storing the original number for comparing later
//logic to compute the reverse of a number
while (n != 0)
remainder = n % 10;
reverse = reverse * 10 + remainder;
n /= 10;
if (reverse == n1)
cout << "\n\nWelcome to Studytonight :-)\n\n\n";
cout << " ===== Program to determine if the entered number is Palindrome or not ===== \n\n";
bool palindrome = false;
//taking input from the command line (user)
cout << " Enter a positive integer : ";
cin >> n;
//Calling a method that returns true if the number is Palindrome
palindrome = isPalindrome(n);
cout << "\n\nThe entered number " << n << " is a Palindrome number.";
cout << "\n\nThe entered number " << n << " is not a Palindrome number.";
cout << "\n\n\n";
