How is Armstrong number calculated?

In case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example: 153 = 1*1*1 + 5*5*5 + 3*3*3 // 153 is an Armstrong number.

What are Armstrong numbers between 1 to 1000?

An Armstrong number is an n-digit base b number such that the sum of its (base b) digits raised to the power n is the number itself. Hence 153 because 13 + 53 + 33 = 1 + 125 + 27 = 153. Here is source code of the C Program to print armstrong number from 1 to 1000.

Is 123 an Armstrong number?

Armstrong Number – Example 11 = 1 , then 1 is an armstrong number. 13 + 53 + 33 = 153, then 153 is an armstrong number. … 13 + 23 + 33 = 36, then 123 is not an armstrong number.
