Access structure members

If you want to access structure members, you need to use a period. Operator in the format:

Structure type variables are defined using the struct keyword. Examples are as follows:

Example

Package main

Import "fmt"

Type Books struct {

Title string

Author string

Subject string

Book_id int

}

Func main () {

Var Book1 Books / * declare Book1 to be of type Books * /

Var Book2 Books / * declare Book2 to be of type Books * /

/ * book 1 description * /

Book1.title = "Go language"

Book1.author = "www.runoob.com"

Book1.subject = "Go language tutorial"

Book1.book_id = 6495407

/ * book 2 description * /

Book2.title = "Python tutorial"

Book2.author = "www.runoob.com"

Book2.subject = "Python language tutorial"

Book2.book_id = 6495700

/ * print Book1 information * /

Fmt.Printf ("Book1 title:% s\ n", Book1.title)

Fmt.Printf ("Book1 author:% s\ n", Book1.author)

Fmt.Printf ("Book1 subject:% s\ n", Book1.subject)

Fmt.Printf ("Book1 book_id:% d\ n", Book1.book_id)

/ * print Book2 information * /

Fmt.Printf ("Book2 title:% s\ n", Book2.title)

Fmt.Printf ("Book2 author:% s\ n", Book2.author)

Fmt.Printf ("Book2 subject:% s\ n", Book2.subject)

Fmt.Printf ("Book2 book_id:% d\ n", Book2.book_id)

}

The execution result of the above example is:

Book 1 title: Go language Book 1 author: Book 1 subject: Go language tutorial Book 1 book_id: 6495407Book 2 title: Python tutorial Book 2 author: Book 2 subject: Python language tutorial Book 2 book_id: 6495700 this is the end of the introduction to "how to access structure members in Go".
