Program 20 Using While loop

Reverse of the given no. is equal to the given no. is known as a Palindrome no.

#include<stdio.h> #include<conio.h> void main()     {             int rev=0,r,n,t=0;             clrscr();             printf("enter a number:");             scanf("%d",&n);             t=n;             while(n!=0)                  {                       r=n%10;                       rev=rev*10+r;                       n=n/10;                  }             if(rev==t)             printf("palindrome");             else             printf("not palindrome");             getch();    }
