For this exercise you must create another project, called Lab12p2.cpp, which again shows the class hierarchy and a new declaration of the base class Employee, which will be used as a starting point:

#include using namespace std;

class Employee { char name[20]; public: //constructors

// virtual function virtual void show_info (){ cout << "Employee" << endl; } };

The steps to be taken are: 1. Enter in the base class the member variable that contains the employee's name. This variable will be private so that derived classes cannot access that value.

char name[20];

2.Create the constructors needed to be able to indicate the name. The constructors of the base class are the only ones that, using the strcpy() function, will assign its value to the name variable. The remaining constructors must call the respective constructor of their base class.

3.Add a public member function to the base class (Employee) so that it returns the name of the employee:

char *getName() { return name; }

4.Build all classes so that they only have to assign the name to the inherited variable. So far they wont have other variables.

5.Redefine show_info() function in all other derived classes so it writes the name of the employee. You must use the getName() function to get the name, since the variable is private.

6.Add the following code to the main function:

Employee Rafa("Rafa"); Manager Mario("Mario"); Worker Anton("Anton"); Officer Luis("Luis"); Technician Pablo("Pablo"); // The type of object pointed by a pointer to the base class // determines the function that is being called Employee *pe; cout << " Inheritance and Polymorphism: " << endl; pe = &Rafa; pe->show_info(); pe = &Mario; pe-> show_info(); pe = &Anton; pe-> show_info(); pe = &Luis; pe-> show_info(); pe = &Pablo; pe-> show_info(); cout << "Ya he terminado." << endl;

7. Now run and compile.
