好的，下面是一个使用C语言实现的简单三子棋（井字棋）游戏代码示例。该游戏允许两个玩家在控制台轮流下棋，直到其中一方获胜或游戏平局。

#include <stdio.h>  
#define SIZE 3  
void initializeBoard(char board[SIZE][SIZE]);  
void printBoard(char board[SIZE][SIZE]);  
int checkWin(char board[SIZE][SIZE]);  
int isBoardFull(char board[SIZE][SIZE]);  
int main() {  
    char board[SIZE][SIZE];  
    int currentPlayer = 1;  
    int row, col;  
    int winner = 0;  
    initializeBoard(board);  
    while (!winner && !isBoardFull(board)) {  
        printBoard(board);  
        printf("Player %d's turn. Enter row and column (1-3, space-separated): ", currentPlayer);  
        scanf("%d %d", &row, &col);  
        row--; // Adjust for 0-based index  
        col--;  
        if (row >= 0 && row < SIZE && col >= 0 && col < SIZE && board[row][col] == ' ') {  
            board[row][col] = (currentPlayer == 1) ? 'X' : 'O';  
            winner = checkWin(board);  
            if (winner) {  
                printBoard(board);  
                printf("Player %d wins!\n", currentPlayer);  
            } else if (isBoardFull(board)) {  
                printBoard(board);  
                printf("It's a draw!\n");  
            } else {  
                currentPlayer = (currentPlayer == 1) ? 2 : 1;  
            }  
        } else {  
            printf("Invalid move. Try again.\n");  
        }  
    }  
    return 0;  
}  
void initializeBoard(char board[SIZE][SIZE]) {  
    for (int i = 0; i < SIZE; i++) {  
        for (int j = 0; j < SIZE; j++) {  
            board[i][j] = ' ';  
        }  
    }  
}  
void printBoard(char board[SIZE][SIZE]) {  
    printf("\n");  
    for (int i = 0; i < SIZE; i++) {  
        for (int j = 0; j < SIZE; j++) {  
            printf(" %c ", board[i][j]);  
            if (j < SIZE - 1) printf("|");  
        }  
        printf("\n");  
        if (i < SIZE - 1) printf("---+---+---\n");  
    }  
    printf("\n");  
}  
int checkWin(char board[SIZE][SIZE]) {  
    for (int i = 0; i < SIZE; i++) {  
        if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][0] != ' ')  
            return 1;  
        if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[0][i] != ' ')  
            return 1;  
    }  
    if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[0][0] != ' ')  
        return 1;  
    if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[0][2] != ' ')  
        return 1;  
    return 0;  
}  
int isBoardFull(char board[SIZE][SIZE]) {  
    for (int i = 0; i < SIZE; i++) {  
        for (int j = 0; j < SIZE; j++) {  
            if (board[i][j] == ' ')  
                return 0;  
        }  
    }  
    return 1;  
}  

说明

1. 初始化棋盘：initializeBoard 函数将棋盘初始化为空格，以表示未被占据的位置。

2. 打印棋盘：printBoard 函数在控制台中以井字棋格式显示当前棋盘状态。

3. 检查胜利条件：checkWin 函数检查是否存在获胜的三连子，无论是行、列或对角线。

4. 检查棋盘是否满：isBoardFull 函数检查棋盘是否还有空位，以判断平局。

5. 主逻辑：使用while循环，实现玩家轮流输入行列，放置棋子并检查胜利或平局情况。

你可以复制这段代码，在你的编译器中运行，并根据需要进行调整和扩展。希望这对你有帮助！
