What are structs and interfaces in Go?

Can you explain what structs and interfaces are in Go?

Sure! In Go, a struct is a composite data type that groups together variables (fields) under a single name. An interface, on the other hand, is a type that specifies a contract by defining methods that a type must implement.

How do I define a struct in Go?

You can define a struct using the type keyword followed by the struct name and its fields. For example: type Person struct { Name string; Age int }.

What about interfaces? How do I define one?

To define an interface, use the type keyword followed by the interface name and the method signatures. For example: type Speaker interface { Speak() string }.

Can a struct implement multiple interfaces?

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