C++ Tic-Tac-Toe Multiplayer Game -- 2

I've completed a console-based Tic-Tac-Toe game using C++ and I'm looking for someone to enhance it.

Some key areas of focus:
- Add Multiplayer Mode: Implement the functionality for two players to play against each other.
- Integrate Difficulty Levels: Incorporate different levels of difficulty for the game, making it more challenging and engaging.

Ideal skills for this project include:
- Proficiency in C++ programming
- Experience with game development
- Familiarity with Object-Oriented Programming (OOPs) concepts
- Ability to follow an existing codebase
- Strong problem-solving abilities
