Question

Write a console program that implements these classes. In main, write a “driver program” that fully tests the functionality of each class.

Your employees have various Set() functions that validate their data, and raise particular types of exceptions for bad data. To keep it simple, just check for null arguments. In real life, you could check the data more thoroughly.

In main, create several Employees. Initialize some at creation with the parameterized constructor, and initialize some after you create them using the Set...() functions.

Put an exception handler in main with catch blocks for EmpNameException, EmpAddressException, EmpPhoneException, EmpException, and a catch(...) default catch block. Make your program throw exceptions by calling the Set() functions with null string arguments. Also test the default catch block by throwing an integer exception with some value if SetName() is called with a value of “Bob”.

getMonthsPay()should throw a EmpException if any data is missing (name, address, or phone), and the message should say which piece of data is missing.

class Employee {
private:
char name[80];
char address[80];
char phone[80];
public:
Employee();
Employee(char * Name, char * Address, char * Phone);
void SetName(char *); // throws EmpNameException
void SetAddress(char *); // throws EmpAddressException
void SetPhone(char *); // throws EmpPhoneException
int GetID();
double getMonthsPay(){return 5000;} // throws EmpException
};

class EmpException {
public:
char msg[80];
EmpException(char *); // use to initialize msg
};

class EmpNameException : public EmpException {
};

class EmpAddressException : public EmpException {
};

class EmpPhoneException : public EmpException {
};
