write a program to check a number is palindrome

              write  a program to  check a number is palindrome  
    
      #include<stdio.h>
         int main()
        {
           int num,r,sum=0,temp;

          printf("Enter a number: ");
          scanf("%d",&num);

          temp=num;
         while(num)
         {
         r=num%10;
         num=num/10;
         sum=sum*10+r;
        }
         if(temp==sum)
         printf("%d is a palindrome",temp);
    else
         printf("%d is not a palindrome",temp);

    return 0;
}

Sample output:
Enter a number: 131
131 is a palindrome
