C + + struct definition and initialization

1 Definition:

struct book{

unsigned int bookno;

String name;

};

2 initialization

The initialization of a struct is divided into three types: one-by-one assignment, sequential assignment, and random-order assignment

Assign values individually:

Book book;
Book.bookno = 123;
Book.name = "iam a book";

Order Assignment

Book Book1 = {, "Book1"};

C + + style in order to assign values

Book Book2 = {

Bookno:123,

Name: "Book2"};

C-style random order assignment

Book BOOK3 = {

. bookno=123,

. Name= "Book3"};
