Answer to Question #214412 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(){
		cout<<"Enter a: ";
		cin>>data_a;
		return data_a;
	}
	int get_b(){
		cout<<"Enter b: ";
		cin>>data_b;
		return data_b;
	}
};


class Arith_Unit: public InputData{
public:
	int add(){

		int data_a=get_a();
		int data_b=get_b();
		return data_a*data_b;
	}

	}
	int xor(){
