Nested Structure in Golang

A structure or struct in Golang is a user-defined type, which allows us to create a group of elements of different types into a single unit. Any real-world entity which has some set of properties or fields can be represented as a struct. Go language allows nested structure. A structure which is the field of another structure is known as Nested Structure. Or in other words, a structure within another structure is known as a Nested Structure. Syntax: 

type struct_name_1 struct{
 // Fields
} 
type struct_name_2 struct{
 variable_name struct_name_1

}

Let us discuss this concept with the help of the examples: 

Example 1: 

Output:

Details of Author
{{Sona ECE 2013}}

Example 2: 

Output:

Details of the Teacher
Teacher's name: Suman
Subject: Java
Experience: 5

Details of Student
Student's name: Bongo
Student's branch name: CSE
Year: 2

Example 3:

In Go, a structure can have fields that are themselves structures, which are called nested structures. Here is an example of a struct that has a nested struct:

Output:

John Doe
Age: 30
Address:
Street: 123 Main St
City: Anytown
State: CA
Postal Code: 12345
 

Here, we define two struct types: Person and Address. Person has a nested struct field Address. In the main function, we create a new Person instance with an Address field. Then, we print out the values of various fields of the Person and Address structs using dot notation to access the nested fields.
