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.

1. #include <iostream>
2. using namespace std;
3. int main()
4. {
5.   int n,r,sum=0,temp;
6.   cout<<"Enter the Number=";
7.   cin>>n;
8.  temp=n;
9.  while(n>0)
10. {
11.  r=n%10;
12.  sum=(sum*10)+r;
13.  n=n/10;
14. }
15. if(temp==sum)
16. cout<<"Number is Palindrome.";
17. else
18. cout<<"Number is not Palindrome.";
19.   return 0;
20. }

Output:

```Enter the Number=121
Number is Palindrome.
```
```Enter the number=113
Number is not Palindrome.```
