Create a class named CellPhone which will represent the code to manage a cell phones operating system

Create a class named CellPhone which will represent the code to manage a cell phone’s operating system

Create a class named CellPhone, split into a header (.h) file and implementation (.cpp) file, that manages a cell phone’s operating system functionality as described below:

The class must include private member variables:

  • An array of structs named contacts to store contact information, with a maximum of 200 contacts. Each Contact struct should contain:
    • First Name
    • Last Name
    • Home contact number
    • Mobile contact number
  • A string named display for the cell phone's display text.
  • A bool named on indicating whether the device is on.
  • A string named currentCall storing the current contact number being called.
  • A bool named callActive indicating if a call is active.

Additionally, private member functions should include:

  • contactCount() - returns the number of contacts stored.
  • showOutput() - outputs the display variable content to the screen.
  • Constructor that sets on to true and initializes display with "Welcome to the CIS3100 Operating System. Your virtual cell phone is now on."

Public member functions should include:

  • newContact() - accepts contact details and stores them if space is available, returning false if not.
  • dialContact() - accepts first and last name, prompts user to select home or mobile number, updates currentCall and display.
  • displayContactNumberInformation() - when given a contact’s number, retrieves the contact and displays their first and last name with formatted output.
  • powerDown() - sets on to false and updates display accordingly.

In every function that updates display, showOutput must be called to display the latest message.

Sample Main Program Using the CellPhone Class

Create a main.cpp that:

  • Displays: "Hello User. Would you like to turn on this cell phone?"
  • If the user agrees, creates an instance of CellPhone and displays a menu with options:
    • A. Turn off cell phone (calls powerDown)
    • B. Add a new contact (newContact)
    • C. Display contact information (displayContactNumberInformation)
    • D. Dial contact (dialContact)
  • The menu repeats until the user chooses to turn off the device.

This design should follow best practices for code organization, including header and implementation files, and adhere to the specifications above.

Introduction

The development of a cell phone simulation program requires a well-structured class design to manage various functionalities such as contact storage, dialing, and power management. The CellPhone class encapsulates all relevant attributes and methods to mimic the behavior of a real-world device. This paper discusses creating the class with proper separation into header and source files, and implementing key features to meet specified requirements.

Design of the CellPhone Class

Struct and Member Variables

The Contact struct encapsulates personal contact details, including first name, last name, home contact number, and mobile contact number. The class maintains an array of such structs with a maximum capacity of 200, managed through private member functions. Additionally, attributes such as display (string), on (bool), currentCall (string), and callActive (bool) track the operational state and ongoing interactions.

Constructor and Private Methods

The constructor initializes the device to an "on" state and sets an initial welcome message in the display. Private methods such as contactCount() help manage contact storage, while showOutput() ensures that any display updates are immediately reflected visually, thus maintaining user interface consistency.

Public Methods

Adding Contacts

The newContact() method accepts contact details and stores them if there is space, returning a boolean to indicate success or failure.

Dialing and Contact Display

The dialContact() method searches for a contact based on names, prompts the user for a choice between home or mobile number, and then updates currentCall and the display accordingly.

The displayContactNumberInformation() method retrieves contact details based on a number and displays formatted information with the contact's name.

Power Management

The powerDown() method turns off the device and updates the display with a shutdown message.

Implementation Strategy

Adopting object-oriented principles, implementation files (.cpp) should define the methods declared in the header, ensuring that display updates invoke showOutput() each time. Careful management of contact storage, search functions, and user prompts follow best practices to maintain code clarity and efficiency.

Sample Main Program

The main.cpp will instantiate the CellPhone class upon user confirmation, then present a recurring menu until the user chooses to turn off the device. User input guides method invocations, providing a realistic simulation of cell phone interactions.

Conclusion

Creating a detailed, functional class for cell phone management involves proper structuring, encapsulation, and adherence to requirements. Separating interface and implementation into header and source files enhances maintainability. The main program orchestrates interaction, ensuring an engaging simulation that closely mimics actual device behavior.
