Answer to Question #213969 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;


//A class called InputData
class InputData{
private:
	// two private data members data_a and data_b. 
	int data_a;
	int data_b;
public:
	//Set the values of these two data members by using two public functions get_a() and get_b().
	int get_a(){
		cout<<"Enter data_a: ";
		cin>>data_a;
		return data_a;
	}
	int get_b(){
		cout<<"Enter data_b: ";
		cin>>data_b;
		return data_b;
	}
};


//Derive a class called Arith_Unit from InputData. 
class Arith_Unit: public InputData{
public:
	//It contains the functions add(),sub(), mul(),div() to perform arithmetic operations on data_a and data_b.
	int add(){
		return (get_a()+get_b());
	}
	int sub(){
		return (get_a()-get_b());
	}
	int mul(){
		return (get_a()*get_b());
	}
	float div(){
		return (get_a()/get_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.
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());
	}
};


//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. 
class  ALUnit: public Arith_Unit, public Logic_Unit{
public:
	void operations(){
		Arith_Unit arith_Unit;
		Logic_Unit logic_Unit;
		int operation=0;
		cout<<"0. 'add' operation\n";

		cout<<"5. 'or' operation\n";

		cout<<"Select operation: ";
		cin>>operation;
		if(operation==0){
			cout<<"Add function result: "<<arith_Unit.add()<<"\n";
		}
		if(operation==1){
			cout<<"Sub function result: "<<arith_Unit.sub()<<"\n";
		}
		if(operation==2){
			cout<<"Mul function result: "<<arith_Unit.mul()<<"\n";
		}
		if(operation==3){
			cout<<"Div function result: "<<arith_Unit.div()<<"\n";
		}
		if(operation==4){
			cout<<"and function result: "<<logic_Unit.and()<<"\n";
		}
		if(operation==5){
			cout<<"or function result: "<<logic_Unit.or()<<"\n";
		}
		if(operation==5){
			cout<<"xor function result: "<<logic_Unit.xor()<<"\n";
		}
	}
};
int main()
{


	//Write sample program to test the ALU class.
	 ALUnit ALUnit;
	 ALUnit.operations();
	
	


	cout<<"\n\n";
	system("pause");
	return 0;
