Armstrong number c program

Armstrong number c program: c programming code to check whether a number is armstrong or not. A number is armstrong if the sum of cubes of individual digits of a number is equal to the number itself. For example 371 is an armstrong number as 33 + 73 + 13 = 371. Some other armstrong numbers are: 0, 1, 153, 370, 407.

C programming code

#include <stdio.h>

#include<conio.h> 

void main()

{

   int num, sum = 0, temp, remainder;

   printf("Enter a number\n");

   scanf("%d",&num);

   temp = num;

   while( temp != 0 )

   {

      remainder = temp%10;

      sum = sum + remainder*remainder*remainder;

      temp = temp/10;

   }

   if ( num == sum )

      printf("Entered number is an armstrong number.\n");

   else

      printf("Entered number is not an armstrong number.\n");

   getch();

}
