Activity 5.01: Calculating the Working Hours of Employees

Solution:

All directories and files should be created inside your $GOPATH:

1. Create a directory called Activity5.01.
2. Create a file called main.go inside Activity5.01.
3. Inside Activity5.01/main.go, declare the main package and its imports:

   package main
   import "fmt"

4. Create a Developer type. Notice the WorkWeek is an array of 7. This is because the week consists of 7 days and we use an array to ensure the fixed size:

   type Developer struct {
     Individual Employee
     HourlyRate int
     WorkWeek   [7]int
   }

5. Create an Employee type:

   type Employee struct {
     Id        int
     FirstName string
     LastName  string
   }

6. Create a Weekday of type int:

   type Weekday int

7. Create a constant of type Weekday. This is an enumeration of the weekdays:

   const (
     Sunday Weekday = iota //starts at zero
     Monday
     Tuesday...
