Question

Please use C++

Suppose we have the following book base class: class book { public: book(char*, char *, int); void show_book(); private: char title[64]; char author[64]; int pages; }; Suppose that we need to derive a new class, called libraryCard class, which adds the following members to the book class: char catalog[64]; int checked_out; // 1 if checked out, otherwise 0 if available libraryCard(char*, char *, int, char *, int); void show_card(); 1. Derive the new class from the base class 2. Implement all the functions 3. Populate the driver program with the sample output and data provided Note: The instantiated object must be of derive class type. SAMPLE OUTPUT **** **** Title: C++ How to Program Author: Deitel & Deitel Pages: 1400 Catalog: 300CPP Status: Checked out

• I used inbuilt strcpy method to copy strings.
• If you want me to add/change anythin, Please let me know by commenting.
• Comments starts with ' // '. Check spellings for printing statements.
• Please refer to the screenshot of the code to understand the indentation of the code
