The Challenge

The challenge was to make a simple “FizzBuzz” program that accepted one integer value into a function called fizzBuzz. The function checks for the following conditions: if the integer is divisible by 3 it returns ‘Fizz’, if the integer is divisible by 5 it returns ‘Buzz’, if the integer is divisible by 3 and 5 it returns ‘FizzBuzz’ and if none of the conditions are met it returns the integer. Example below

1 --> 1
2 --> 2
3 --> Fizz
4 --> 4
5 --> Buzz
6 --> Fizz
7 --> 7
8 --> 8
9 --> Fizz
10 --> Buzz
11 --> 11
12 --> Fizz
13 --> 13
14 --> 14
15 --> FizzBuzz
16 --> 16
17 --> 17
18 --> Fizz
19 --> 19
20 --> Buzz

            if (result == "") return num.ToString(); else return result;
        }
