Refactor your war.cpp program by introducing functions to handle different aspects of the game. You will be provided with function prototypes to guide your implementation.

What to Do

Part 1: Review and Prepare

• Ensure your display is correct. Correct any mistakes before proceeding.

Part 2: Implementing Functions

You are provided with the following function prototypes. Implement each function according to its description.

Function Prototype: void preparation();

• Description: Set up any initial states or configurations needed before the game starts. This function does not require input from the user or return any values.
• What it improves: Encapsulates the setup logic, making the main function cleaner.

Function Prototype: void drawCards(int &card1Value, int &card1Suit, int &card2Value, int &card2Suit);

• Description: Randomly selects two different cards from the deck and assigns their values and suits to the reference parameters provided.
• What it improves: Isolates the card drawing logic, making it reusable and testable.

Function Prototype: void displayCards(const int card1Value, const int card1Suit, const int card2Value, const int card2Suit);

• Description: Clears the screen, displays the game title, and shows the two drawn cards using the values provided.
• What it improves: Separates the display logic from the game logic, allowing for different display options in the future.

Function Prototype: void statistics(int &totalBattles, int &youWon, int &youLost, int &tie, const int card1Value, const int card2Value);

• Description: Updates and displays the game statistics. It modifies the total battles, wins, and ties based on the current hand.
• What it improves: Centralizes the statistics tracking, making it easier to add new statistics in the future.

Function Prototype: bool continueBattle();

• Description: Prompts the user to decide whether to continue the game and returns true for 'y' or false for 'n'.
• What it improves: Provides a clear decision point for continuing the game, making the main function's flow easier to understand.
