A positive integer is called an Armstrong number of order n if:
Source Code: Check Armstrong number
Here, we ask the user for a number and check if it is an Armstrong number.
We need to calculate the sum of the n-power of each digit. So, we initialize the
sum to 0 and obtain each digit number by using the modulus operator
%. The remainder of a number when it is divided by 10 is the last digit of that number. We take the n-power using exponent
Finally, we compare the sum with the original number and conclude that it is Armstrong number if they are equal.
