declaring an array in go struct code example

Example 1: how to make struct type as array in go

package main

import "fmt"

type rectangle struct {
	length  int
	breadth int
	color   string
}

func main() {
	var rect1 = &rectangle{10, 20, "Green"} // Can't skip any value
	fmt.Println(rect1)

	var rect2 = &rectangle{}
	rect2.length = 10
	rect2.color = "Red"
	fmt.Println(rect2) // breadth skipped

	var rect3 = &rectangle{}
	(*rect3).breadth = 10
	(*rect3).color = "Blue"
	fmt.Println(rect3) // length skipped
}

Example 2: how to make struct type as array in go

package main

import "fmt"

type Salary struct {
	Basic, HRA, TA float64
}

type Employee struct {
	FirstName, LastName, Email string
	Age                        int
	MonthlySalary              []Salary
}

func (e Employee) EmpInfo() string {
	fmt.Println(e.FirstName, e.LastName)
	fmt.Println(e.Age)
	fmt.Println(e.Email)
	for _, info := range e.MonthlySalary {
		fmt.Println("===================")
		fmt.Println(info.Basic)
		fmt.Println(info.HRA)
		fmt.Println(info.TA)
	}
	return "----------------------"
}

func main() {

	e := Employee{
		FirstName: "Mark",
		LastName:  "Jones",
		Email:     "[email protected]",
		Age:       25,
		MonthlySalary: []Salary{
			Salary{
				Basic: 15000.00,
				HRA:   5000.00,
				TA:    2000.00,
			},
			Salary{
				Basic: 16000.00,
				HRA:   5000.00,
				TA:    2100.00,
			},
			Salary{
				Basic: 17000.00,
				HRA:   5000.00,
				TA:    2200.00,
			},
		},
	}

	fmt.Println(e.EmpInfo())
}
