2. Logic and Loops

Activity 2.01: Implementing FizzBuzz

Solution:

1. Define package and include import:

   package main
   import (
     "fmt"
     "strconv"
   )

2. Create the main function:

   func main() {

3. Create a for loop that starts at 1 and loops until i gets to 100:

     for i := 1; i <= 100; i++{

4. Initialize a string variable that will hold the output:

     out := ""

5. Using module logic to check for divisibility, if i is divisible by 3, then add "Fizz" to the out string:

     if i%3 == 0 {
     out += "Fizz"
     }

6. If divisible by 5, add "Buzz" to the string:

     if i%5 == 0 {
     out += "Buzz"
     }

7. If neither, convert the number to a string and then add it to the output string:

     if out == "" {
     out = strconv.Itoa(i)
     }

8. Print the output variable:

     fmt.Println(out)
