       << endl;
cout << "How much memory do you need? ";
cin >> i;

FlashDrive f( i, 0,

false );
cout << "Let's format the drive..." << endl;
f.formatDrive();
cout << "Let's plug in the drive..." << endl;
f.plugIn();
cout << "Let's write some data..." << endl;

bool my_IsPluggedIn; part b: flashdrive_driver I have provided you with a sample class named FlashDrive which has been diagrammed below and described in the online course content. For this unit, I'd like you to identify additional member variables (data) that would be appropriate for the class FlashDrive. I would also like you to identify additional methods (functions) that would be appropriate for the class FlashDrive. Submit a .h file for FlashDrive with the new possible methods and members you have identified commented and explained.

Explanation / Answer

class FlashDrive
{
    public:
        FlashDrive();   //A default constructor.
        FlashDrive(int caparcity, int used, bool pluggedIn);   //Parameterized constructor.
       
        void plugIn();   //Plugs-in the drive, i.e., sets my_IsPluggedIn to true.
        void pullOut();   //Pulls-out the drive, i.e., sets my_IsPluggedIn to false.
        void writeData(int amount);   //Writes an amount of data to drive.
        void eraseData(int amount);   //Removes an amount of data from drive.
        void formatDrive();   //Removes all data from drive.
       
        int getUsed();   //Gets the amount of data used.
        void setUsed(int amount);   //Sets the amount of data used.
       
        int getCapacity();   //Gets the capacity of drive.
        void setCapacity();   //Sets the capacity of the drive.
       
        bool isFull();   //Checks if the drive is readily full, and cannot be written.
        bool isEmpty();   //Checks if the drive is empty, and cannot be erased further.
        bool isPluggedIn();   //Checks if drive is plugged in or not.
    private:
        int my_StorageCapacity;
        int my_StorageUsed;
        bool my_IsPluggedIn;  
};
