Answer to Question #213305 in C++ for Hemambar

Question

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.
