# Armstrong Numbers Welcome to Armstrong Numbers on Exercism's C Track. If you need help running the tests or submitting your code, check out `HELP.md`. ## Instructions An [Armstrong number](https://en.wikipedia.org/wiki/Narcissistic_number) is a number that is the sum of its own digits each raised to the power of the number of digits. For example: - 9 is an Armstrong number, because `9 = 9^1 = 9` - 10 is *not* an Armstrong number, because `10 != 1^2 + 0^2 = 1` - 153 is an Armstrong number, because: `153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153` - 154 is *not* an Armstrong number, because: `154 != 1^3 + 5^3 + 4^3 = 1 + 125 + 64 = 190` Write some code to determine whether a number is an Armstrong number. ## Source ### Created by - @wolf99 ### Contributed to by - @computermouth - @elyashiv - @ryanplusplus ### Based on Wikipedia - https://en.wikipedia.org/wiki/Narcissistic_number
