Question

I need help with documentation for my header files

I need documentation for each line.

```cpp
/*
 * CheckingAccount.h
 * Header file for CheckingAccount class
 * @file CheckingAccount.h
 * @author Javaria Basit
 */

#ifndef CHECKINGACCOUNT_H
#define CHECKINGACCOUNT_H
#include "BankAccount.h"
using namespace std;

class CheckingAccount : public BankAccount {
private:
    int transactions;
    void check_for_fee();
public:
    CheckingAccount();
    CheckingAccount(string, double);
    void withdraw(double);
    void deposit(double);
    void month_end();
};

#endif
```

### Explanation

This C++ header file, `CheckingAccount.h`, defines a `CheckingAccount` class which inherits from a `BankAccount` class. Here are the main components:

- **Include Guards**: 
  - `#ifndef CHECKINGACCOUNT_H` and `#define CHECKINGACCOUNT_H` are used to prevent multiple inclusions of this file.

- **Includes**: 
  - `#include "BankAccount.h"`: This includes the header file for the base class `BankAccount`.

- **Namespace**: 
  - `using namespace std;` allows usage of the standard namespace.

- **Class Structure**:
  - **Private Members**:
    - `int transactions;` — to hold the number of transactions.
    - `void check_for_fee();` — a method to apply fees based on transactions.
  
  - **Public Members**:
    - `CheckingAccount();` — default constructor.
    - `CheckingAccount(string, double);` — constructor with parameters for account initialization.
    - `void withdraw(double);` — method to withdraw funds.
    - `void deposit(double);` — method to deposit funds.
    - `void month_end();` — method to handle end of month processes.

- **End of File**: 
  - `#endif` closes the include guard.

### Compilation Information

- The compiler output shows that various object files were generated for the different classes and linked into an executable named `bankTest`.
- The compilation finished successfully, indicating no syntax errors were present.

/* SavingsAccount.h
 * Header file for SavingsAccount class
 * @file SavingsAccount.h
 * @author Javaria Basit
 * This file SavingsAccount.h consist of class SavingsAccount and it is a private class
 * This is also a derived class for the base class BankAccount
 */

#ifndef SAVINGSACCOUNT_H
#define SAVINGSACCOUNT_H
#include "BankAccount.h"
using namespace std;

class SavingsAccount : public BankAccount {
private:
    double interest_rate;
    double min_balance;
public:
    SavingsAccount();
    SavingsAccount(string, double, double);
    void withdraw(double);
    void set_interest_rate(double);
    double get_interest_rate();
    void display_balance();
    void month_end();
};

#endif
```

**Explanation:**
- The code is a header file in C++ defining the `SavingsAccount` class.
- It inherits from a base class `BankAccount`.
- It includes private member variables `interest_rate` and `min_balance`.
- Public member functions include constructors, methods to withdraw, set and get interest rate, display balance, and handle end-of-month operations.
- The code uses preprocessor directives to avoid multiple inclusions.
- The compilation in the bottom indicates no errors: "Compilation finished successfully."
