Palindrome Program In C++

A palindrome number is a number that is same after reverse. For example 121, 34543, 343, 131, 48984 are the palindrome numbers.

Palindrome number algorithm

• ✅ Get the number from user
• ✅ Hold the number in temporary variable
• ✅ Reverse the number
• ✅ Compare the temporary number with reversed number
• ✅ If both numbers are same, print palindrome number
• ✅ Else print not palindrome number

Let's see the palindrome program in C++. In this program, we will get an input from the user and check whether number is palindrome or not.

Example

#include <iostream>

using namespace std;

int main()

{

  int n,r,sum=0,temp;  

  cout<<"Enter the Number=";  

  cin>>n;  

 temp=n;  

 while(n>0)  

{  

 r=n%10;  

 sum=(sum*10)+r;  

 n=n/10;  

}  

if(temp==sum)  

cout<<"Number is Palindrome.";  

else  

cout<<"Number is not Palindrome."; 

  return 0;

}

Output:

Enter the Number=121   

 Number is Palindrome.

Enter the number=113  

Number is not Palindrome.
