Course Description
This course introduces more advanced steps to program design and is a continuation of CISS 241. A disciplined approach to problem solving and algorithm development will be stressed using top down design. Topics include strings, pointers, recursion, classes, and methods, and operator overloading.

Course Overview
This class is the second in a three course sequence, a continuation of CISS 241, introducing computer
programming using the C++ language. This class uses the C++ programming language, but the principles learned and skills obtained are applicable to programming in any language. In fact, one of the objectives of this course is to instill the ability to transfer your knowledge and skills to programming in any domain, with any language.

Assignment 1
Payroll. Write a class name Payroll, with the class declaration in a file called Payroll.h and the implementation in a file called Payroll.cpp. The class will have data members for an employee’s hourly pay rate, number of hours worked and calculate the total pay for the week. All of the data members will be doubles. The class only needs one constructor which can be a default constructor that sets all data members to zero. Then add the mutators and accessor for the class. The program will have an array of 7 Payroll objects. The program will prompt the user for number of hours each employee has worked and will then display the amount of gross pay each has earned. Before asking the user for the hours, the program
should set the pay rate for each employee without user input. Validation: Do not accept values greater than 60 for the number of hours worked.

Assignment 2
Cash Register. This program will use two classes; one of the classes is provided in the assignment description for week 7 in the course site. Write a class name CashRegister, with the class declaration in a file called CashRegister.h and the implementation in a file called CashRegister.cpp. This class will interact with the InventoryItem class that has been provided. The program should display a list of items that are available to purchase.

The program will ask the user for the item and quantity being purchased. It will then get the cost of the item from the InventoryItem object. It will add 30% profit to the cost of the item to get the item’s unit price. It will then multiply the unit price times the quantity being purchased to get the purchase subtotal. The program will then compute a 6% sales tax on the subtotal to get the purchase total. It should then display the purchase subtotal, tax and total on the screen. The program will then subtract the quantity being purchased from the onHand variable of the InventoryItem class object. InventoryItem will need to be modified to handle this.
Validation: Do not accept a negative value for the quantity of items being purchased.

CISS 242 Week 6 Introduction to Classes

Assignment 1
Employee Class. Write a class named Employee, with the class declaration in a file called
Employee.h and the implementation in a file called Employee.cpp. The class should have the
following data members:

name – A string that holds the employee’s name
idNumber – An int variable that holds the employee’s ID number
department – a string that holds the name of the department where the employee works
position – A string that holds the employee’s job status

The class must have the following constructors:

A constructor that accepts the following values as arguments and assigns them to the appropriate member
variables: employee’s name, employee’s ID number, department and position.
A constructor that accepts the following values as arguments and assigns them to the appropriate member variable: employee’s name, employee’s ID number. The department and position fields should be assigned an empty string (“ “).
A default constructor that assigns empty string (“”) to the name, department and position member variables and 0 to the idNumber member variable.

Write the appropriate mutator functions that store values in these member variables and accessor functions that return the values in these member variables. Once you have written the class, write a separate program that creates 3 instances of the Employee class. Each instance of the class should use a different constructor than the other 2 objects (so all three constructors must be used). Main should use a function called displayEmployee that has one parameter which is a pointer to a constant Employee object. Main will call the function 3 times to display the information for each of the 3 instances of the Employee class.
void displayEmployee(Employee* const e);
The output of the program must be in the form of a table.

Assignment 2
Circle Class. Write a class name Circle, with the class declaration in a file called Circle.h and
the implementation in a file called Circle.cpp. The class will have two data members, a double that holds the radius of the circle and a double called pi which will be set to the value, 3.14159 (data member cannot be set in the class declaration, pi should not be set via a parameter but set in the constructor). The class must provide the following member functions

Default Constructor – that sets the radius to 0.0
Constructor – that accepts the radius of the circle as an argument
setRadius – a mutator function for the radius variable
getRadius – an accessor function for the radius variable
getArea – calculates and returns (as double) the area of the circle using the formula
1
area = pi * radius * radius
getDiameter – calculates and returns (as double) the diameter of the circle using the formula
1
diameter = radius * 2
getCircumference – calculates and returns (as double) the circumference of the circle using the formula
1
circumference = 2 * pi * radius

Write a program that demonstrates the Circle class by asking the user for the circle’s radius and creating a Circle object and then reporting the circle’s area, diameter and circumference. Two objects
need to be created each using one of the two constructors (showing that both work along with the mutators and accessors)
