You just have to input a number and then my programme will calculate the Armstrong numbers from 0-999! ( If you do not know what Armstrong numbers are, keep reading and I will tell you what they are. Armstrong numbers are numbers in which if you take each of the digits in the number and put that to the power of the length of digits and then add them all up, you will get that number. For example: 371 is an Armstrong number because: 3**3 + 7**3+ 1**3= 371! P.S try that number in my programme
