Write a program to reverse a number. e.g.: if the is 876 then output will be 678

#include<stdio.h> int main()    {       Int   n, r, temp;       printf( "Enter an integer number: " );       scanf( "%d" , &n);       temp=n;       r=0;       while(n>0)         {           r=r*10 + n%10;           n=n/10;          }       printf( "\nReverse of %d = %d" , temp, r);       return 0;  }
