What is Fizz Buzz?

Simply put, a “Fizz-Buzz test” is a programming interview question designed to help filter out potential job prospects – those who can’t seem to program if their life depended on it.

An example of a typical Fizz-Buzz question is the following:

Write a program which prints the numbers from 1 to 100. But for multiples of three, print the word “Fizz” instead of the number, and for the multiples of five, print the word “Buzz”. For numbers which are multiples of both three and five, print the word “FizzBuzz”.

This seems easy enough, and many should be able to complete a program which carries out a solution in a few minutes. Though, after doing a little research, apparently that is not the case. This page will present one way to carry out a solution to this Fizz-Buzz problem.

There is a small “catch” that some may encounter when trying to solve this problem, and that is the fact that the conditional statement for the number divisible by 15 should come before each sequential conditional statement. Consider this pseudocode:

The portion that may make this problem tricky for some is the fact that the conditional statement for the number divisible by 15 must be checked -before- the conditional statements which checks for numbers divisible by 3 and 5. If the conditional statements are placed in any other order, the end result will not be correct, which is what can make the problem difficult for many.

So building upon the pseudocode found from above, utilizing the modulus operator, here is a simple solution to the Fizz Buzz Test
