How to Run the Game:
1. Save the C++ code into a file named 'TicTacToe.cpp'.
2. Compile the code using the command: g++ -o TicTacToe TicTacToe.cpp
3. Run the executable in the command line: ./TicTacToe
Game Explanation:
- The game consists of a 3x3 grid where two players take turns marking their spaces (one with 'X'
and the other with 'O').
- The game starts with Player 1 using 'X'.
- Players enter their moves by specifying the row and column numbers where they want to place
their mark.
- The game checks for a win or a draw after every move.
- The game ends when one player has three of their marks in a row, column, or diagonal, or when all
spaces are filled, resulting in a draw.
