How do I use structs and interfaces in Go?

In Go, structs are used to define complex data types, while interfaces allow you to define methods that can be implemented by different types.

Can you give me an example of a struct and an interface?

Sure! Here's a simple example:

type Person struct {
    Name string
    Age  int
}

type Greeter interface {
    Greet() string
}

func (p Person) Greet() string {
    return "Hello, my name is " + p.Name
}

How do I implement the interface in a different struct?

You can implement the interface in another struct by defining the same method. For example:

type Animal struct {
    Species string
}

func (a Animal) Greet() string {
    return "I am a " + a.Species
}

What are the benefits of using interfaces?

Interfaces promote flexibility and decoupling in your code, allowing different types to be used interchangeably as long as they implement the same methods.
