Define a class Employee with data members as empno, name and designation. Derive a class Qualification from Employee that has data members UG, PG and experience. Create another class Salary which is derived from both these classes to display the details of the employee and compute their increments based on their experience and qualifications.

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 performarithmetic 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 performarithmetic and logical operations according to the given codes. Choose code 0 to code 6 to performthe said seven operations. Write sample program to test the ALU class.

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 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.

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 having class STRING, With data member which can store character array (Dynamically you can store). It should facility to initialize by parameterize constructor and concatenate STRING objects.

Ex:   STRING  obj1(“OOP”), obj2 (“IN KIIT”);

         Obj1 = obj1 + obj2;

Then obj1 should have “ OOP IN KIIT”   string in it.
