Activity: Fizz Buzz

Graded Playground Autograder

Activity Prompt:

In this problem, you will write a solution to the Fizz Buzz problem (description to follow) within the body of the function FizzBuzz. I understand that we haven't discussed functions in detail yet. What you need to know is that our auto-grader will invoke your implementation (the code within the function body) with an integer value to initialize the parameter int n.

You will write your definition of Fizz Buzz between the curly braces and with respect to the value stored in the parameter n. Your function will return a string literal based on the value of n:

  • The string literal Fizz (return "Fizz";) if n is divisible by 3
  • The string literal Buzz if n is divisible by 5
  • The string literal FizzBuzz if n is divisible by 3 and 5
  • The n encoded as a string (return std::to_string(n);) if n is not divisible by 3 and/or 5
Hint: the modulus operator will likely prove useful in this problem.

You will define FizzBuzz in You can test your implementation in by calling FizzBuzz with different arguments.
#include <string> std::string FizzBuzz(int n) { // write your solution here! }
#include <iostream> std::string FizzBuzz(int n); int main() { std::cout << FizzBuzz(3) << std::endl; std::cout << FizzBuzz(5) << std::endl; std::cout << FizzBuzz(7) << std::endl; std::cout << FizzBuzz(15) << std::endl; }
