Learn Go in 3 Hours - Structs

This video tutorial covers the concept of structs in Go programming, explaining their creation, initialization, and advanced features like copying and pointers. It highlights the differences between structs and objects, focusing on the lack of inheritance in Go and the use of embedding and delegation. The tutorial also demonstrates how to use struct tags for JSON marshalling and unmarshalling, providing practical examples and code snippets.

What is a key difference between structs and objects in Go?

• Structs are not used in Go.

• Structs support inheritance.

• Structs do not support inheritance.

• Structs can only contain primitive data types.

Which keyword is used to declare a new struct in Go?

• object

• struct

• class

• type

How are public fields in structs indicated in Go?

• By using lowercase letters.

• By using uppercase letters.

• By using special symbols.

• By using underscores.

What happens when you assign one struct to another in Go?

• The values are copied to a new memory location.

• The structs share the same memory location.

• The structs become linked.

• The structs are merged.

How can you access a field within a struct in Go?

• Using the field index.

• Using the variable name followed by a dot and the field name.

• Using a pointer.

• Using the field name directly.

What is the purpose of embedding in Go structs?

• To create a subtype relationship.

• To provide inheritance.

• To reuse a struct across multiple structs.

• To hide struct fields.

What is a struct tag used for in Go?

• To add metadata to a struct field.

• To define a struct's visibility.

• To create a new struct type.

• To initialize a struct.
