Question

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.

Answer 1

The C++ code is as follows:-

#include <iostream>
using namespace std;
class book
{
public:
book(char *t,char *a,int p)
{
std::copy(t, t+64, title);
std::copy(a, a+64, author);
pages=p;
}
void show_book() //implementing function
{
cout<<"Title: "<<title<<endl;
cout<<"Author: "<<author<<endl;
cout<<"Pages: "<<pages<<endl;
}
private:
char title[64];
char author[64];
int pages;
};
class libraryCard: public book //derive new class from base class
{
public:
char catelog[64];
int checked_out;
libraryCard(char * t,char * a,int p,char * c,int co):book(t,a,p)
{
std::copy(c, c+64, catelog);
checked_out=co;
}
void show_card() //implementing function
{
book::show_book();
cout<<"Catelog: "<<catelog<<endl;
if(checked_out==1)
cout<<"Status: Checked out";
else
cout<<"Status: Available";
}
};
int main()
{
libraryCard obj("C++ How to Program","Deitel & Deitel",1400,"300CPP",1); //creating object
obj.show_card(); //function calling
return 0;
}

The output of the above code is as follows:-
