C++ LANGUAGE (Referring to the code below)

1. Write and test a friend function that checks to see if the phone number of a an Employee object is equal to the phone number of a Programmer object. Test equal and not equal scenarios. (You will need to call your ChangePhoneNumber method)

2. Overload the equality operator to see if the phone number of two Employees are the same. Test equal and not equal scenarios. (You will need to call your ChangePhoneNumber method)

3. Write an addition member function that adds an integer to an Employees age (make sure the integer is a passed parameter). The output should state how many years were added to the age.

4. Overload the addition operator to add a constant to an Employees age. For example: StarEmployee = StarEmployee + 2. The output should state how many years were added to the age.

5. Overload << and >> operators to read in an Employee object (e.g. cin >> myEmployee and cout << myEmployee)

6. Overload the pre & post increment operators to increment an Employees age. Test pre/post increment operations. Output the values of Employee objects before and after pre/post increment operations as well as after assignment takes place. Demonstrate how pre/post increment operators are different. Which overloaded operator incurs the most overhead?

The code to refer to:

// Employee class

class Employee {

protected:

string name; string phone; int age;

public:

Employee(); Employee(string name, string phone, int age); void setName(string name); void setPhoneNum(string phone); void setAge(int age); };

// default constructor

Employee::Employee() {

name = ""; phone = ""; age = 0; }

// overloaded constructor

Employee::Employee(string name, string phone, int age) {

this->name = name; this->phone = phone; this->age = age; }

// Employee class setter functions

void Employee::setName(string name) {

this->name = name; }

// ----------

void Employee::setPhoneNum(string phone) {

this->phone = phone; }

// ----------

void Employee::setAge(int age) {

this->age = age; }

// Employee class getter functions

string Employee::getName() {

return name; }

// ----------

string Employee::getPhoneNum() {

return phone; }

// ----------

int Employee::getAge() {

return age; }

Programmer class is a subclass of Employee, inherits and calls the same methods of the base (Employee) class so I didn't write the whole thing.

I would greatly appreciate your help!
