Write a C program for a Tic-Tac-Toe game.

Here is a short C program for a Tic-Tac-Toe game. `c #include <stdio.h> // Required for input/output functions like printf and scanf // Global 3x3 board to store game state char board[3][3]; // Function to initialize the board with empty spaces void initializeBoard() int i, j; for (i = 0; i < 3; i++) for (j = 0; j < 3; j++) board[i][j] = ' '; // Each cell is initialized as an empty space // Function to display the current state of the Tic-Tac-Toe board void displayBoard() printf(" Tic-Tac-Toe"); printf(" %c | %c | %c", board[0][0], board[0][1], board[0][2]); printf("---|---|---"); printf(" %c | %c | %c", board[1][0], board[1][1], board[1][2]); printf("---|---|---"); printf(" %c | %c | %c", board[2][0], board[2][1], board[2][2]); printf(""); // Function to check if any player has won // Returns 1 if 'X' wins, 2 if 'O' wins, 0 if no winner yet int checkWin() int i; // Check rows for a win for (i = 0; i < 3; i++) if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ') return (board[i][0] == 'X') ? 1 : 2; // Check columns for a win for (i = 0; i < 3; i++) if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ') return (board[0][i] == 'X') ? 1 : 2; // Check main diagonal (top-left to bottom-right) for a win if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[0][0] != ' ') return (board[0][0] == 'X') ? 1 : 2; // Check anti-diagonal (top-right to bottom-left) for a win if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[0][2] != ' ') return (board[0][2] == 'X') ? 1 : 2; return 0; // No winner found // Main function where the game logic runs int main() int player = 1; // Player 1 ('X') or Player 2 ('O') int i, row, col; char mark; // 'X' or 'O' int gameStatus = 0; // 0 = game in progress, 1 = X wins, 2 = O wins, -1 = draw initializeBoard(); // Set up the empty board // Game loop runs for a maximum of 9 turns (3x3 board) or until a win for (i = 0; i < 9 && gameStatus == 0; i++) displayBoard(); // Show the current board state // Determine current player and their mark player = (i % 2 == 0) ? 1 : 2; // Player 1 for even turns, Player 2 for odd mark = (player == 1) ?
