# Palindrome program in C

Palindrome number 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 c program, we will get an input from the user and check whether number is palindrome or not.

1. #include<stdio.h>
2. #include<conio.h>
3. main()
4. {
5. int n,r,sum=0,temp;
6. clrscr();
7. printf(“enter the number=”);
8. scanf(“%d”,&n);
9. temp=n;
10. while(n>0)
11. {
12. r=n%10;
13. sum=(sum*10)+r;
14. n=n/10;
15. }
16. if(temp==sum)
17. printf(“palindrome number “);
18. else
19. printf(“not palindrome”);
20. getch();
21. }

Output:

```enter the number=151
palindrome  number
```
```enter the number=5621
not palindrome  number```
