Answer to Question #231238 in C++ for Billu

Question

Provide an improved declaration for the Customer class that exploits the principles of reusability. Provide the interface only. (b) Implement the constructor for the derived Customer class. (c) Consider the partial class declaration of an Employee class below: class Employee: protected Person{ public: //... double Rate; double GetRate() const; double GetHours() const; private: double Hours; //... protected: double Pay() const; //... }; (i) The code fragment below (extracted from a main() function) has three invalid statements. Write down the line numbers of the invalid statements and explain why each of these statements is invalid. E is an instance of an Employee object.

Answer 1

#include<iostream>
using namespace std;
class Customer{
	private:
		string name;
		int custID;
	public:
		Customer(){
			
		}
		Customer(string n, int id){
			name = n;
			custID = id;
		}
		void input(){
			cout<<"Enter customer name\n";
			cin>>name;
			cout<<"Enter customer id\n";
			cin>>custID;
		}
		void display(){
			cout<<"The customer name is:  "<<name;
			cout<<"\nThe customer id is:  "<<custID;
		}
		
};
int main(){
	Customer c;
	c.input();
	c.display();
}
