4. Program to determine palindrome number 

#include<stdio.h>
#include<conio.h> // Linux user - Remove this

int main()
{
// variable for a=number, n=to copy number, d=digit, rev=reverse of number
int a,n,d=0,rev=0;

// Inputting number
printf("Enter any number to determine whether it is Palindrome or not:");
scanf("%d",&a);

// copying number in n
n=a;

// Determining whether number is palindrome or not
while(n!=0)
{
           d=n%10;
           rev=rev*10+d;
           n=n/10;
           }
           
           // Displaying Whether number is palindrome or not
           if(a==rev)
           printf("Palindrome number");
           else
           printf("Not a Palindrome Number");
          
     getch(); // Linux user - Remove this

     return 0;
     
     }
