Start with the following class declaration:
// base class
class Cd { // represents a CD disk
private:
char performers[50];
char label[20];
int selections; // number of selections
double playtime; // playing time in minutes
public:
Cd(char * s1, char * s2, int n, double x);
Cd(const Cd & d);
Cd();
~Cd();
void Report() const; // reports all CD data
Cd & operator=(const Cd & d);
};
Derive a Classic class that adds an array of char members that will hold a string identifying the primary work on the CD. If the base class requires that any functions be virtual, modify the base-class declaration to make it so. If a declared method is not needed, remove it from the definition. Test your product with the
following program:
#include
using namespace std;
#include "classic.h" // which will contain #include cd.h

void Bravo(const Cd & disk);
int main()
{
Cd c1("Beatles", "Capitol", 14, 35.5);
Classic c2 = Classic("Piano Sonata in B flat, Fantasia in C",
"Alfred Brendel", "Philips", 2, 57.17);
Cd *pcd = &c1;
cout << "Using object directly:\n";
c1.Report(); // use Cd method
c2.Report(); // use Classic method
cout << "Using type cd * pointer to objects:\n";
pcd->Report(); // use Cd method for cd object
pcd = &c2;
pcd->Report(); // use Classic method for classic object
cout << "Calling a function with a Cd reference argument:\n";
Bravo(c1);
Bravo(c2);
cout << "Testing assignment: ";
Classic copy;
copy = c2;
copy.Report()
return 0;
}
void Bravo(const Cd & disk)
{
disk.Report();
}
