fizzBuzz.cpp

// Create a function that takes a number as an argument and returns "Fizz", "Buzz" or "FizzBuzz".

// If the number is a multiple of 3 the output should be "Fizz".
// If the number given is a multiple of 5, the output should be "Buzz".
// If the number given is a multiple of both 3 and 5, the output should be "FizzBuzz".
// If the number is not a multiple of either 3 or 5, the number should be output on its own as shown in the
// examples below.
// The output should always be a string even if it is not a multiple of 3 or 5.
// Examples
// fizzBuzz(3) ➞ "Fizz"

// fizzBuzz(5) ➞ "Buzz"

// fizzBuzz(15) ➞ "FizzBuzz"

// fizzBuzz(4) ➞ "4"
