Question

Design a BankAccount class (Links to an external site.) that has the following member variables (Links to an external site.): • custName: a string • balance: a double

The class (Links to an external site.) should have the following member functions:

• Default Constructor (Links to an external site.). A default constructor (Links to an external site.) that sets custName as empty string and balance as 0. • Constructor (Links to an external site.). Accepts the custName and balance as arguments (Links to an external site.).

• setCustName. A mutator function for the custName variable (Links to an external site.).

• getCustName. An accessor function for the custName variable (Links to an external site.).

• setBalance. A mutator function for the balance variable (Links to an external site.).

• getBalance. An accessor function for the balance variable (Links to an external site.).

• deposit(double amount). Add the deposit amount passed in to the balance, assume the amount is not negative.

• withdrawal(double amount). Subtract the withdrawal amount from the balance. Assume the amount is not negative and is not greater than the balance.

Create an instance/object of BankAccount class using default constructor. Set the balance and customer name. Add $100 deposit by calling the deposit method. Subtract $50 withdrawal by calling the the withdrawal method. Display customer name and final balance.

C++ CODE:

#include <iostream>
#include <string>

using namespace std;

class BankAccount{
private:
    string custName;
    double balance;

public:
    // Default constructor
    BankAccount() : custName(""), balance(0) {}

    // Constructor
    BankAccount(string name, double bal) : custName(name), balance(bal) {}

    // Accessor
    string getCustName() const {
        return custName;
    }

    // Mutator
    void setCustName(string custName) {
        this->custName = custName;
    }

    // Accessor
    double getBalance() const {
        return balance;
    }

    // Mutator
    void setBalance(double balance) {
        this->balance = balance;
    }

    // Method to deposit amount
    void deposit(double amount) {
        this->balance += amount;
    }

    // Method to withdraw amount
    void withdraw(double amount) {
        this->balance -= amount;
    }
};

int main(){
    BankAccount b;
    b.setBalance(150.0);
    b.setCustName("John Doe");
    b.deposit(100.0);
    b.withdraw(50.0);
    cout << "Customer name: " << b.getCustName() << endl;
    cout << "Final balance: $" << b.getBalance() << endl;
    return 0;
}
