Question

Code the following Program in C++

Define a class named Payment that contains a member variable of type float that stores the amount of the payment and appropriate accessor and mutator methods.   

Also create a member function named paymentDetails that outputs an English sentence that describes the amount of the payment.

Next define a class named CashPayment that is derived from Payment. This class should redefine the paymentDetails function to indicate that the payment is in cash. Include appropriate constructor(s).

Define a class named CreditCardPayment that is derived from Payment. This class should contain member variables for the name on the card, expiration date, and credit card number.   Include appropriate constructor(s). Finally, redefine the paymentDetails function to include all credit card information in the printout.

Create a main method that creates at least two CashPayment and two CreditCardPayment objects with different values and calls paymentDetails for each.

Code -

#include <iostream>

using namespace std;
//class paymeth
class Payment{
//variable delcare
public:
float amountOfPayment;
//paymentDetails function
void paymentDetails(){
cout<<"Amount of payment "<<getAmountPayment()<<endl;
}
//getter for amount
float getAmountPayment(){
return amountOfPayment;
}
//setter for amount
void setAmountPayment(float amount){
amountOfPayment = amount;
}
  
};
//class CashPayment inherits Payment class
class CashPayment : public Payment{
//constructor CashPayment
public:
CashPayment(float amount){
amountOfPayment = amount;
}
//override paymentDetails function
void paymentDetails(){
cout<<"Amount paid as cash is "<<amountOfPayment<<endl;
}
};
//class CreditCardPayment inherits Payment class
class CreditCardPayment : public Payment{
//variable declare
string name , expiryDate,creditCardNumber;
//constructor credit card class
public:
CreditCardPayment(string nameCard,string expiry,string cardNo,float amount){
name = nameCard;
expiryDate = expiry;
creditCardNumber = cardNo;
amountOfPayment = amount;
}
// paymentDetails function
void paymentDetails(){
cout<<"Name on card "<<name<<" Expiry date "<<expiryDate<<" Card number "<<creditCardNumber<<" Amount due "<<amountOfPayment<<endl;
}
};

int main()
{
//Payment class object
Payment p1;
//setter method
p1.setAmountPayment(2500);
//print payment
p1.paymentDetails();
//CashPayment object first
CashPayment c1(3000);
//paymentDetails print
c1.paymentDetails();
//CashPayment object second
CashPayment c2(5000);
c2.paymentDetails();
//CreditCardPayment object first
CreditCardPayment cc1("John","22-12-2021","123456789",5343);
cc1.paymentDetails();
//CreditCardPayment object first
CreditCardPayment cc2("Bryan","10-2-2022","987654321",1234);
cc2.paymentDetails();
return 0;
}
