This project is a simple implementation of the classic Hangman game using C++. The game is designed using Object-Oriented Programming (OOP) principles, which helps in organizing the code and making it more maintainable and scalable.

The game is encapsulated in a class named HangmanGame. This class contains both the data members and member functions that define the behavior of the game.

• game_over: A boolean that indicates whether the game is over.
• choice: An integer that stores the user's menu choice.
• random_line: An integer that stores the line number of the randomly selected word.
• word, line, count, guess, word_length: Various private members used in the game logic.

• menu(): Displays the game menu to the user.
• add_word(): Allows the user to add a new word to the game.
• exit_game(): Exits the game.
• dashes_for_word(string word): Replaces the letters in the word with dashes.
• random_line_selector(): Selects a random line number from the words file.
• print_the_word(int random_line): Prints the word at the given line number.
• guess_letter_in_dashed_word(string word): Allows the user to guess a letter in the word.

The game is designed using the principles of OOP. The HangmanGame class encapsulates the data and functions related to the game, providing a clear interface and hiding the implementation details. This makes the code easier to understand, maintain, and modify.

The game starts by displaying a menu with three options: Play Game, Add Word, and Exit. The user can choose to start a new game, add a new word to the game, or exit the game. During the game, the user is asked to guess a letter in the hidden word. The game continues until the user guesses the whole word or chooses to exit the game.
