Armstrong number program in c

Armstrong Number(Or Narcissistic Number):
An Armstrong number is a number such that the sum of its digits raised to the no.of digits power is equal to the number itself.
Explnation:To declare a number is an Armstrong number, first determine how many digits are in the number. Call that n. Then take every digit in the number and raise it to the n power. Add all those together, and if your answer is the original number then it is an "Armstrong Number"

#include<stdio.h>

void main()
{

int number,orignum,rem,result=0;

printf("enter a three digit number to check whether it is armstrong or not");

scanf("%d",&number);

orignum=number;

while(orignum!=0)

result+rem*rem*rem;
orignum=orignum/10;
}

if(result==number)

printf("%d is armstrong number ",number);

else

printf("%d is not armstrong number",number);

}

OUTPUT:
1: enter a three digit number to check whether it is armstrong or not 371

371 is armstrong number

2: enter a three digit number to check whether it is armstrong or not 456
456 is not armstrong number

perfect number program in c

Perfect Number :A perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself.
