What are the differences between interfaces and structs in Go?

What are the differences between interfaces and structs in Go?

In Go, structs are used to define data structures, while interfaces define a set of methods that a type must implement.

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

Sure! A struct could be type Person struct { Name string; Age int }, and an interface could be type Speaker interface { Speak() string }.

How do I implement an interface in a struct?

To implement an interface, a struct must define all the methods declared in the interface. For example, if Person implements Speaker, it would need a Speak method.

What are the advantages of using interfaces over structs?

Interfaces provide flexibility and allow for polymorphism, enabling different types to be treated as the same type if they implement the same interface.
