How to embed a struct into another struct in Go?

In Go, you can embed a struct into another struct using anonymous fields. Here's an example:

package main

import "fmt"

type Address struct {
    Street   string
    City     string
    ZipCode  string
}

type Person struct {
    Name    string
    Age     int
    Address // embedding Address struct here
}

func main() {
    p := Person{
        Name: "John",
        Age:  30,
        Address: Address{
            Street:  "123 Main St",
            City:    "New York",
            ZipCode: "10001",
        },
    }

    fmt.Println(p.Name)               // Output: John
    fmt.Println(p.Age)                // Output: 30
    fmt.Println(p.Address.Street)     // Output: 123 Main St
    fmt.Println(p.Address.City)       // Output: New York
    fmt.Println(p.Address.ZipCode)    // Output: 10001
}

In this example, we have defined two structs: Address and Person. The Address struct represents a person's address, and the Person struct represents a person with their name, age, and address.

The Address struct is embedded anonymously inside the Person struct using the struct name as the field name. This allows the Person struct to directly access the fields of the embedded Address struct.

To create a new Person object, you can initialize it with the desired fields, including the embedded Address struct. You can then access the embedded fields using dot notation as shown in the main function.
