How to Write a Palindrome number Program & its Execution Steps 

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

Lets see how to write a Program of palindrome number using in C langusge. 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
