Defining structures

In order to define the structure, you must use a struct statement. A struct statement defines a new data type that contains multiple members, with the format of the struct statement as follows:

struct type_name { member_type1 member_name1; < Span class= "Hl-code" > member_type2 member_name2; < Span class= "Hl-code" > member_type3 member_ Name3 . . } object_names; typedef keyword

The following is a simpler way to define the structure, and you can take an "alias" for the type you create. For example:

typedef struct< Span class= "PLN" >{ char title [50]; char Author[50]; char Subject[100  int Book_id;}books;          

You can now use Books directly to define variables of type Books , without using the struct keyword. Here is an example:

BooksBook1,Book2;
