Slice of Struct in Go (Golang) - Welcome To Golang By Example

Overview

It is possible to create a slice of struct in Golang as well. In fact, a slice can be created of any data type in Go. Below is a simple example to create a slice of structs

Program

package main

import "fmt"

type employee struct {
	name string
	age  int
}

func main() {
	employees := make([]employee, 3)

	employees[0] = employee{name: "John", age: 21}
	employees[1] = employee{name: "Simon", age: 25}
	employees[2] = employee{name: "David", age: 18}

	for _, e := range employees {
		fmt.Println(e)
	}
}

Output

{John 21}
{Simon 25}
{David 18}

In the above program, we created a struct named employee

type employee struct {
	name string
	age  int
}

Then we created a slice of struct like this

employees := make([]employee, 3)

This is how we can create a slice of struct
