Create a class named EB_amount. It has the data members units_used and bill. Use member

function to set unit_used. Upto 200 units 3 rupees per unit, 201 to 500, 4 rupees per and above 500

5.5 rupees per unit are allotted by EB. Calculate the bill amount and display the amount. Create

another class Salary with basic, DA and HRA. Set basic by a member function. 104 percent of basic

is assigned as DA and 10 percent is allotted as HRA. Display the total salary. Derive a class Budget

contains income, tuition_fee, house_rent, saving, grocery, eb_bill as data members. Set the values

and get the values of income and eb_bill from parent classes. Display the budget details.

Create a base class called Shape which has two double type values. Use member functions get()

and set() to get and set the values. Use a virtual function display_area() to display the area. Derive

two specific classes called Triangle and Rectangle from the base class Shape. Redefine

display_area() in the derived classes. Write a program to display the rectangle or triangle area.

Write a program for a publishing company that markets both printed books and audio visual

lectures stored on CDs. Write a class Publication thatstores title and price. Derive a class book which

has an additional member as no_pages and a class Lecture with member play_time.

Write a program that has a class Train with data members seats_first_class, seats_second_class

and seats_ac_2tier and member functions to set and display data. Derive a class Reservation that has

data members booked_first_class, booked_second_class and booked_ac_2tier and functions to book

and cancel tickets and display status.

Create a class called Transmitter. It has three unsigned int private data members: pay_load,

parity and data_packet; It has one function called parity_bit(). It calculates parity bit by XORing

all pay_load bits and assign the value to parity. By using function get pay_load(), pay_load is got.

data_packet is calculated by multiplying parity_bit with 32768 and add the product with (pay_load

– 32768). Create another class called Receiver. It has unsigned int private data members Rx_Pkt

, Rx_Data and E_Flag. Rx_Data is got from Rx_Data as given below. First E_Flag is calculated

from Rx_Pkt by XORing all bits. If E_Flag is zero, then Rx_Data = Rx_Pkt – 32768, Else a

message should warn about corrupted packet. Derive a class called Tranceiver from the above two

classes and check the functionalities. Use any other functions if needed.

Create a class called InputData. It has two private data members data_a and data_b. Set the

values of these two data members by using two public functions get_a() and get_b(). Derive a class

called Arith_Unit from InputData. It contains the functions add(),sub(), mul(),div() to perform

arithmetic operations on data_a and data_b. Derive a class Logic_Unit from InputData. It

contains the functions and(), or() and xor() to perform logical operations on data_a and data_b.

Finally derive a class called ALUnit from Arith_Unit and Logic_Unit classes. It has to perform

arithmetic and logical operations according to the given codes. Choose code 0 to code 6 to perform

the said seven operations. Write sample program to test the ALU class.

write a function called findsequence.

the function takes a 4-digit integer as parameter, validates and returns 1 when the digits are in increasing order or 2 when the digits are in decreasing order or 0 when the digits are not in any order.

Define a class Student with data members as rollno and name. Derive a class Fees from student

that has a data member fees and functions to submit fees and generate receipt. Derive another class

Result from Student that displays the marks and grade obtained by the student. Write a program that

extends the class Result so that the final result of the Student is evaluated based on the marks obtained

in tests, activities and sports.

Write a program that has a class Train with data members seats_first_class, seats_second_class

and seats_ac_2tier and member functions to set and display data. Derive a class Reservation that has

data members booked_first_class, booked_second_class and booked_ac_2tier and functions to book

and cancel tickets and display status.
