Code# 35:C Program To Check Armstrong Number or Not

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.
#include <stdio.h>

main()
{
   int number, sum = 0, temp, remainder;

   printf("Enter a number\n");      
   scanf("%d",&number);

   temp = number;

   while( temp != 0 )
   {
      remainder = temp%10;
      sum = sum + remainder*remainder*remainder;
      temp = temp/10; 
   }

   if ( number == sum )
      printf("Entered number is an armstrong number.");
   else
      printf("Entered number is not an armstrong number.");         

   return 0;
}
Output:
Enter a number
407
Entered number is an armstrong number
