  • C++ typedef的一个用法

    1.不适用typedef:

    #include <iostream>
    #include <cstring>
    using namespace std;
    struct Books
    {
        char  title[50];
        char  author[50];
        char  subject[100];
        int   book_id;
    };
    
    int main()
    {
        struct Books book;
    
        strcpy(book.title, "C 教程");
        strcpy(book.author, "Runoob");
        strcpy(book.subject, "编程语言");
        book.book_id = 12345;
    
        printf("书标题 : %s
    ", book.title);
        printf("书作者 : %s
    ", book.author);
        printf("书类目 : %s
    ", book.subject);
        printf("书 ID : %d
    ", book.book_id);
        system("pause");
        return 0;
    }

    2.使用typedef:

    #include <iostream>
    #include <cstring>
    using namespace std;
    typedef struct Books
    {
        char  title[50];
        char  author[50];
        char  subject[100];
        int   book_id;
    };
    
    int main()
    {
        struct Books book;
    
        strcpy(book.title, "C 教程");
        strcpy(book.author, "Runoob");
        strcpy(book.subject, "编程语言");
        book.book_id = 12345;
    
        printf("书标题 : %s
    ", book.title);
        printf("书作者 : %s
    ", book.author);
        printf("书类目 : %s
    ", book.subject);
        printf("书 ID : %d
    ", book.book_id);
        system("pause");
        return 0;
    }
