Definition of Armstrong Number: 

What is an Armstrong Number? A number is thought of as an Armstrong number if the sum of its own digits raised to the power number of digits gives the number itself. 

For example, 153, 370, 371, 407 are three-digit Armstrong numbers 

and, 1634, 8208, 9474 are four-digit Armstrong numbers and there are many more.

Input: 1634

Output: 1634 is an Armstrong number.

Input: 152

Output: 152 is not an Armstrong number.

Code Snippet:

#include<stdio.h>

int main() {

    int num, originalNum, remainder, result = 0;

    printf("Enter a three-digit integer: ");

    scanf("%d", &num);

    originalNum = num;

    while (originalNum != 0) {

        remainder = originalNum % 10;

        result += remainder*remainder*remainder;

        originalNum /= 10;

    }

    if (result == num)

        printf("%d is an Armstrong number.", num);

    else

        printf("%d is not an Armstrong number.", num);

    return 0;

}
