What are structs and interfaces in Go?

In Go, structs are composite data types that group together variables (fields) under a single name. Interfaces define a contract that types can implement.

Can you give me an example of a struct in Go?

Sure! Here's a simple example:

type Person struct {
    Name string
    Age  int
}

This defines a Person struct with Name and Age fields.

How do interfaces work in Go?

Interfaces in Go specify methods that a type must implement. For example:

type Speaker interface {
    Speak() string
}

Any type that has a Speak method satisfies the Speaker interface.

Can a struct implement multiple interfaces?

Yes, a struct can implement multiple interfaces by defining the required methods for each interface.
