Course synopsis This course introduces the concepts of object-oriented programming to students with a background in the procedural paradigm. The course begins with a brief review of control structures and data types with emphasis on structured data types and array processing. It then moves on to introduce the objectoriented programming paradigm, focusing on the definition and use of classes along with the fundamentals of object-oriented design. Other topics include inheritance, polymorphism, operator overloading, exception handling, templates and STLs. Students will learn about these concepts in a C++ development environment.

Objective This course provides in-depth coverage of object-oriented programming principles and techniques using C++. Topics include classes, overloading, data abstraction, information hiding, encapsulation, inheritance, polymorphism, file processing, templates, exceptions, container classes, and low-level language features

Learning Outcomes: At the end of the course, students will be able to:      

Describe Object Oriented Programming Tackle real world problems through Object Oriented Programming Handle Operator overloading Implement Inheritance, Polymorphism, Encapsulation and related features of OOP Handle Constructors & Destructors Implement Generic Programming Concepts and manipulate exception handling

Week-5 5.1 OBJECTIVE 3. To create an Array of an object 4. Making use of Objects as function parameters 3. Making use of static data members 4. To create a constant data member and classes 5. To create friend functions & friend classes 5.2 RESOURCE: Visual Studio  C++ 5.3 PROCEDURE Go to Build -> run or press F5 to run the program. Experiment: 1 Design a Payroll class that has data members for an employee’s hourly pay rate, number of hours worked, and total pay for the week. Write a program with an array of seven Payroll objects. The program should ask the user for the number of hours each employee has worked and will then display the amount of gross pay each has earned. Input Validation: Do not accept values greater than 60 for the number of hours worked. Experiment: 2 The objective of this exercise is to understand the declaration of a class with its data members and Member functions. Also, the concept of passing objects as function parameters. Create a class Travel with two data members kilometer and hour, class member functions input, show and add, which accept an object of Travel as parameter. It adds the values of data members of the parameter object and the value of the calling object’s data members and displays the result. Declare two objects t1 and t2 of class Travel and input data in both objects. Call the add function with t1 object and pass t2 object as an argument. Travel km : int hr : int Travel() ~Travel() input() : void show() : void Add(Travel p) : void Experiment: 3 The objective of this exercise is to understand the concept of static data members. Write a class definition Capital with one static data member count, which count number of objects created of particular class. A UML diagram of this class is given as: Capital count : int static Capital() show() void

:

13

Define variable count and initialize it to 0. This variable will be defined outside the class because it will be not part of any object. It is created only once in the memory and shared among all objects of the class. The variable definition outside the class must be proceeded with class name and scope resolution operator :: The compiler does not display an error of the static data member is not defined. The linker will generate an error when the program is executed. Create three objects x, y and z of Capital class. Each time an object is created, the constructor is executed that increases the value of the static count variable by 1.

Experiment: 4 The objective of this exercise is to understand the concept of const object type arguments and arguments passing by reference. Problem Statement Write a class definition ComplexNumber with two data members’ realPart and imaginaryPart. We wish to perform addition, subtraction and multiplication with objects of ComplexNumber class. A complex number c = a + bj consists of two parts, the real part a and the imaginary part bj. We can perform arithmetic operations (+, -, *, /, or addition, subtraction, multiplication) on complex numbers as follows: +: (a1 + b1j) + ( a2 + b2j) = (a1 + a2) + (b1 + b2)j -: (a1 + b1j) – (a2 + b2j) = (a1 – a2) + (b1 – b2)j *: (a1 + b1j) * (a2 + b2j) = (a1a2 – b1b2) + (a1b2 + a2b1) j A UML diagram of this class is given as: ComplexNumber realPart : double imaginaryPart : double Complex () ~Complex () Complex (double, double) add (const Complex&) : Complex sub (const Complex& ) : Complex mul(const Complex& ) : Complex print() : void const

Create objects of this class and test all the member functions. Experiment: 5 The objective of this exercise is to how to learn the friend function of a class. Room width : double printWidth(Room) : friend void setWidth(double) : void Procedure Do the exercise and create an object of the Room class and call the setWidth() function to pass 10.10 as the argument value. Later print the width of the room by calling the printWidth(Room) function. But see this function is a friend of the Room class, so this will not be a member of the class. Therefore we shall define it outside the class, rather than using the :: operators with the class member function definition.
