• x, y coordinates
• a constructor with two parameters representing x, y coordinates (their default values are allowed to be 0)
• a member function named display, which prints out two coordinates on the screen.
• A member function named getInfo, which accepts two input data from the user for x, y coordinates.
• Two member functions named setX, setY to update values to x, y, respectively.
• Two member functions named getX, getY to retrieve values from x, y, respectively.
• A member function named distance, which accepts as parameter an object of class CPoint and calculates the distance from the object invoking the function to the parameter object.

b. Construct a derived class named CPoint_3D from the class CPoint, described as follows:

• There is one more data member: coordinate z.
• There are overriding member functions in CPoint_3D for all corresponding member functions in the class CPoint.

c. Include the class constructed in a) and b) in a working C++ program. Have your program call all of the member functions in the CPoint_3D class.

## Project 1

This project aims to review all the chapters from Chapter 1 (Introduction to Computers and Programming) to Chapter 6 (Functions and Pointers) which focus on structured programming.

An example of Project 1 can be described as follows:

The Colossus Airlines fleet consists of one plane with a seating capacity of 12. It makes one flight daily. Write a seating reservation program with the following features:

• The program uses an array of 12 structures. Each structure should hold a seat identification number, a marker that indicates whether the seat is assigned and the name of the seat holder. Assume that the name of a customer is not more than 20 characters long.
• The program displays the following menu with six choices:
• Show the number of empty seats
• Show the list of empty seats.
• Show the list of customers together with their seat numbers in the order of the seat numbers
• Assign a customer to a seat
• Remove a seat assignment
• Quit
• The program successfully executes the promises of its menu. Choices (4) and (5) need additional input from the user which is done inside the respective functions.
• After executing a particular function, the program shows the menu again, except for choice (6).

## Project 2

This project aims to review all the chapters from Chapter 7 (Introduction to Classes) to Chapter 8 (Object Manipulation - Inheritance) which focus on the basics of object-oriented programming.

An example of Project 2 can be described as follows:

A stack is an ordered collection of data items in which access is possible only at one end, called the top of the stack with the following basic operations:

• Push: add an element to the top of the stack.
• Pop: remove and return the top element of the stack.
• Check if the stack is empty
• Check if the stack is full.

It would be nice to have a stack class, because we could then use it to easily develop some applications which need stack data structure.

For the moment, assume that we need to define an integer stack class. Since a stack must stores a collection of integers, we can use an integer array to model the stack and a “pointer” named Top to indicate the location of the top of the stack. The array should have a fixed size. So we can begin the declaration of the class by selection two data members:

• Provide an integer array data member to hold the stack elements (the size of the array is a constant).
• Provide an integer data member to indicate the top of the stack.

As for the member functions of the stack class, we have to define 5 member functions: the constructor which creates an empty stack and four other member functions (push, pop, check if the stack is empty, check if the stack is full).

After defining the stack class, write a main() function which does the following tasks:

• Creating one stack object.
• Pushing into the stack object ten integer elements which take values from 1 to 10 with the increment of 1.
• Popping one by one element from the stack object and displaying it out, repeating this action until the stack becomes empty.

Next, apply the stack data structure in solving the following problem: write a program that accepts a string from the user and prints the string backward. (Hint: Use a character stack)

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
