Answer to Question #212998 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.

Answer 1

#include <iostream>


using namespace std;


class InputData{
    private:
        int data_a;
        int data_b;
    public:
        int get_a(){
            data_a=45;
            return data_a;
        }
        int get_b(){
            data_b=45;
            return data_b;
        }
};


class Arith_Unit: public InputData{
    public:
        int add(){
            return (get_a()+get_b());
        }
        int sub(){
            return (get_a()-get_b());
        }
        int mul(){
            return (get_a()*get_b());
        }
        int div(){
            return (get_a()/get_b());
        }
};


class  Logic_Unit: public InputData{
    public:
        int and_(){
            return (get_a()&&get_b());
        }
        int or_(){
            return (get_a()||get_b());
        }
        int xor_(){
            return (!get_a()||get_b());
        }
};


class  ALUnit: public Arith_Unit, public Logic_Unit{
    
};
int main()
{
    InputData e;
    e.get_a();
    e.get_b();


    return 0;
