Programming Task

Programming task:


Task_A
Create a class Employee with following constraints in mind;
_ Declare two data members named firstName and lastName of string type.
_ Implement a parameterized constructor, which will take firstName and lastName of an employee and initialized the respective data members.
_ Implement a print function that displays the complete name (firstName lastName) of an Employee.
Task_B
Test the working of your created Employee class with the help of a main program.
Task_C
Create a class HourlyWorker which inherits from Employee class publically with following constraints in mind;
_ Declare two data members named wage and hours of double type with private access.
_ Implement a parameterized constructor, which initializes all the data members of HourlyWorker class.
_ Implement a getPay function that calculate and return the salary (hours * wage) of particular
HourlyWorker employee.
_ Implement a print function that displays the complete name and salary of a particular employee.
Task_D
Test the working of your created HourlyWorker class with the help of a main program.
Programming Task 02
Implement the following class hierarchy, the inheritance access level should be protected for Reptile, Bird and
Mammal on the other hand it should be private for Snake, Parrot and Horse classes.




Task _A
Add a protected data member named id of integer type to Animal class.
Task_B
Add get/set methods for id data member in Animal class with public access.
Task_C
Add a default constructor to each of the above created class. The constructor should initialize the id data member of Animal, Reptile, Bird and Mammal, to 0, 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”.
Task_D
Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member of Animal, Reptile, Bird and Mammal, to the specified id passed to the constructor also it display a message “(class Name)’s default constructor”. The parameterized constructor should call its base class parameterized constructor to initialize any data member inherited from the base class.
Task_E
Add a destructor to each of the above created class. The destructor should display a message “(class Name)’s default destructor”.
Task_F
Add a getFamily method to Snake, Parrot and Horse classes, this method must return the id of a particular animal’s family where it belongs to.
Task_G
Add a tellAboutSelf method to Animal class with public access. The method displays the name of each objects class where it belongs to.
Task_H
Override the tellAboutSelf in all the sub-leaving classes of Animal with the same functionality as in Animal class.
Task_I
Add a speak method to Animal class and override it in each of the sub-leaving classes. The Animal, Reptile, Bird, Mammal, Snake, Parrot and Horse can speak by printing a message “I am Animal, I cant speak…”, “Family of Reptiles…” “Family of Birds…”, “Family of Mammals…”, “Shhh….”, “Trrrr….” and “Hurrrrr…” respectively.
Task_J

Write down your main method and instantiate object of each class created above, call tellAboutSelf, speak and getFamily methods for each of the created object.            Note the mechanism in which constructors and destructors are called.
