A Harshad number is a positive integer which is exactly divisible by the sum of its digits. The first twelve Harshad numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12 and 18
36 is a Harshad number. The digits of 36 are 3 and 6; the sum of these digits is 9 as 3 + 6 = 9 and 36 is exactly divisible by 9 (36 ÷ 9 = 4)
300 is a Harshad number. The digits of 300 are 3, 0 and 0; the sum of these digits is 3 as 3 + 0 + 0 = 3 and 300 is exactly divisible by 3 (300 ÷ 3 = 100)
15 is not a Harshad number. The digits of 15 are 1 and 5; the sum of these digits is 6 as 1 + 5 = 6 and 15 is not exactly divisible by 6
What you need to do
Write a program that asks the user to enter a number, n, and will then calculate and display the nth Harshad number.
You may assume that the number that the user enters will be a positive integer.
Evidence that you need to provide
- Your PROGRAM SOURCE CODE.
- SCREEN CAPTURE(S) showing the result of testing the program by entering the number 600
