Tic-Tac-Toe Game

This is a simple Tic-Tac-Toe game implemented in C++. It supports both two-player mode and player vs. system mode with selectable difficulty levels and move orders. The game is played on a 3x3 grid, and players alternate turns to place their mark ('x' or 'o') on the grid, aiming to be the first to get three marks in a row (horizontally, vertically, or diagonally).

Features

• Two-Player Mode: Allows two players to play locally.
• Player vs System Mode: The player can play against the system, with different difficulty levels.
• Difficulty Levels:
  • Novice: The system makes random moves.
  • Expert: The system uses a more intelligent algorithm to block and win.
  • Unbeatable: The system uses a perfect strategy (Minimax algorithm) to never lose.(Not Available Right now)
• Move Order Selection: Choose to go first, second, or let the game decide randomly.
• Game State Display: The current state of the game board is displayed after each move.
• Input Validation: Ensures only valid moves are made.
