Fizz Buzz Implementation
Given an integer n, for every integer i <= n, the task is to print “FizzBuzz” if i is divisible by 3 and 5, “Fizz” if i is divisible by 3, “Buzz” if i is divisible by 5 or i (as a string) if none of the conditions are true.
Example:
Input: n = 3
Output: [1 2 Fizz]Input: n = 5
Output: [1 2 Fizz 4 Buzz]Input: n = 19
Output: [1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz 16 17 Fizz 19 Buzz]
Approach:
Iterate on the given number from 1 to n, check its divisibility and add the string into result according to the given condition.
- Initialize an empty result list.
- Iterate on the given number from 1 to n
- For every number, if it is divisible by both 3 and 5, add FizzBuzz to the result list.
- Else, Check if the number is divisible by 3, add Fizz.
- Else, Check if the number is divisible by 5, add Buzz.
- Else, add the number by converting it to string.
- Print the result.
Below is the implementation of the above approach:
C++
#include <bits/stdc++.h>using namespace std;vector<string> fizzBuzz(int n){ // Declare a vector of strings to store the results vector<string> result; // Loop from 1 to n (inclusive) for (int i = 1; i <= n; ++i) { // Check if i is divisible by both 3 and 5 if (i % 3 == 0 && i % 5 == 0) { // Add "FizzBuzz" to the result vector result.push_back("FizzBuzz"); } // Check if i is divisible by 3 else if (i % 3 == 0) { // Add "Fizz" to the result vector result.push_back("Fizz"); } // Check if i is divisible by 5 else if (i % 5 == 0) { // Add "Buzz" to the result vector result.push_back("Buzz"); } else { // Add the current number as a string to the // result vector result.push_back(to_string(i)); } } // Return the result vector return result;}// Driver codeint main(){ int n = 20; // Call the fizzBuzz function to get the result vector<string> result = fizzBuzz(n); // Print the result for (const string& s : result) { cout << s << " "; } return 0;} |

Output
1 2 Fizz 4 Buzz Fizz 7 8 Fizz Buzz 11 Fizz 13 14 FizzBuzz 16 17 Fizz 19 Buzz
