Question

The class declaration (interface) and the function definitions (implementation) must be in separate files - the interface or "header" file has a .hpp extension and the implementation has a .cpp extension. As usual, all data members should be private.

Write a class called BankAccount that has:

a string data member called customerName, a string data member called customerID, and a double data member called customerBalance

a constructor that takes two strings and a double (name, ID, balance) and uses them to initialize the data members. The data members of this class do not need to be set after they are initialized, so this class doesn't need any set methods - therefore the constructor will directly assign values to the data members instead of calling set methods to do it.

a get method for each data member

a method called withdraw that takes a double parameter and deducts it from the customer balance (the balance is allowed to be negative) - this method should not have a return value

a method called deposit that takes a double parameter and adds it to the current balance - this method should not have a return value

The BankAccount class might be used as follows:

BankAccount account1("Harry Potter", "K4637", 8032.78);
account1.withdraw(244.0);
account1.withdraw(3012.58);
account1.deposit(37.54);
account1.withdraw(1807.12);
account1.deposit(500.00);
double finalBalance = account1.getCustomerBalance();

BankAccount.hpp should have "include guards" as discussed on page 447.

BankAccount.cpp needs to #include BankAccount.hpp. When you include your own .hpp files (header files), put double quotes around them instead of angled brackets. (You should only #include .hpp files, not .cpp files.)

Put your main function in a separate file (this is the "client" code) and give it a name with a .cpp extension.

The file with your main method also needs to #include BankAccount.hpp.

If you named the file with your main method "bankAccountMain.cpp", then you can compile your program with "g++ BankAccount.cpp bankAccountMain.cpp -o bank", for example.

BankAccount.hpp

#ifndef BANKACCOUNT_HPP
#define BANKACCOUNT_HPP
class BankAccount
{
public:
BankAccount();
BankAccount(string name,string accno,double bal);

// Function declarations
void withdraw(double amt);
void deposit(double amt);
double getCustomerBalance();
  
void setName(string name);
string getName();
void setAccountNo(string accNO);
string getAccountNo();
double getBalance();
void setbalance(double bal);
  

private:
// Declaring variables
string name;
string accno;
double bal;

};
#endif

BankAccount.cpp
