Answer to Question #215266 in C++ for Dharshini Priya

Question

Create a class called InputData. It has two private data members data_a (int) and data_b (int). Write a function input() to get input for the attributes from the user and a function display() to display the values of the attributes. The values of these two data members can be returned 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 bitwise operations on data_a and data_b.

Write a main() to test functionalities of the Arith_unit and Logic_unit classes.
