C++ Lab

Programs on object oriented concepts would be administered in the Lab with each topic covered in the theory.

1. An election is contested by five candidates. The candidates are numbered 1 to 5 & voting is done by marking the candidate number on the ballot paper. Write a program to read the ballot & count the votes cast for each candidate using an array, variable count. In case, a number read is outside the range 1 to 5, the ballot should be considered as a ' spoilt ballot' and the program should also count the number of spoilt ballot.
2. Define a class to represent a bank account including the following members: - Data members

a) Name of the depositors

b) Account number

c) Type of account

d) Balance amount in the account Member function

- To assign initial values

- To deposit an amount

- To withdraw an amount after checking the balance

- To display the name and balance.

3. Create 2 classes OM and DB which store the value of distance. DM store distances in meters and cm and DB in feet and inches. Write a program that can read values for the class objects and add 1 object OM with another object of DB. .

Use a friend function to carry out the addition operation the object that stores the results may be a DM object or a DB object, depending upon the units in which the results are require. The display should be in the format of feet and inches or meters and cms depending on the object on display.

4. Create a base class called shape use this class to store two double type values that could be used to compute the area of fig. Derive the specific class called TRIANGLE and RECTANGLE from the data shape. Add to base class, a member function get - data ( ) to initialize base class data members and another member and another member function display – area ( ) to compute and display the area of the fig. Make display – area ( ) as a virtual function and redefine function in the derived classes to suit their requirements,

Using these 3 classes design a program that will accept dimension of RECTANGLE or TRIANGLE interactivity and display the area. Remember the 2 values given as input will be treated as length of 2 sides in the case of rectangle and as base and height in the case of triangles and used as follows:

Area of rectangle = x*y

Area of triangle = 1/2 *x*y

Project Work: This mini project is based on Object Oriented Programming using C++. Simple projects such as inventory Management System, Payroll System, Library management System, Job Scheduling, Hardware Interface, Network Monitoring System etc. can be created.

Project must be done in a group of 2-4 students.

• Final Evaluation will be done by:

1. Project Demonstration
2. Power Point Presentation

• The marks of the mini project would be given on the basis of internal assessment of the project as given in the course structure.
