Accessing Fields in Nested Structs in Go

In Go, when you have a struct that embeds another struct, you can access the fields of the inner struct through the instance of the outer struct using the dot (.) operator. Here’s a simple example to illustrate how to access fields in a nested struct:

package main

import "fmt"

type Inner struct {
    Field1 string
}

type Outer struct {
    Inner Inner
}

func main() {
    // Creating an instance of the Outer struct
    outer := Outer{
        Inner: Inner{
            Field1: "Hello",
        },
    }

    // Accessing the Field1 field of the Inner struct
    fmt.Println(outer.Inner.Field1) // Output: Hello
}

In this example, the Outer struct embeds the Inner struct. To access the Field1 field of Inner, you need to go through the instance of Outer, outer, which is done by outer.Inner.Field1. This is the correct way to access fields in nested structs in Go.
