c语言五子棋游戏

好的，我可以为您提供一个简单的C语言五子棋游戏的代码示例，如下所示：

#include <stdio.h>
#include <stdlib.h>

#define ROWS 15
#define COLS 15

void init_board(char board[][COLS], int rows, int cols);  // 初始化棋盘
void display_board(char board[][COLS], int rows, int cols);  // 显示棋盘
void player_move(char board[][COLS], int rows, int cols);  // 玩家下棋
void computer_move(char board[][COLS], int rows, int cols);  // 计算机下棋
char check_win(char board[][COLS], int rows, int cols);  // 判断胜负

int main()
{
    char board[ROWS][COLS];
    init_board(board, ROWS, COLS);
    display_board(board, ROWS, COLS);

    char winner = 0;
    while (1)
    {
        player_move(board, ROWS, COLS);
        display_board(board, ROWS, COLS);
        winner = check_win(board, ROWS, COLS);
        if (winner)
            break;

        computer_move(board, ROWS, COLS);
        display_board(board, ROWS, COLS);
        winner = check_win(board, ROWS, COLS);
        if (winner)
            break;
    }

    if (winner == 'X')
        printf("You win!\n");
    else if (winner == 'O')
        printf("Computer wins!\n");
    else
        printf("It's a tie!\n");

    return 0;
}

void init_board(char board[][COLS], int rows, int cols)
{
    for (int i = 0; i < rows; i++)
    {

    }
}

void player_move(char board[][COLS], int rows, int cols)
{
    int row, col;
    printf("Please enter your move (row column): ");
    scanf("%d %d", &row, &col);

    while (row < 1 || row > ROWS || col < 1 || col > COLS || board[row-1][col-1] != '+')
    {
        printf("Invalid move. Please enter your move (row column): ");
        scanf("%d %d", &row, &col);
    }

    board[row-1][col-1] = 'X';
}

void computer_move(char board[][COLS], int rows, int cols)

            }
        }
    }

    // 检查左上-右下对角线
    for (int i = 0; i <= rows - 5; i++)
    {
        for (int j = 0; j <= cols - 5; j++)
        {
            if (board[i][j] == '+' ||

    // 没有胜者
    for (int i = 0; i < rows; i++)

            {
                return 0;
            }
        }
    }

    // 平局
    return 'T';
}

这个五子棋游戏使用了一个二维字符数组 `board` 来表示棋盘，其中 `+` 表示空位，`X` 表示玩家下的棋，`O` 表示计算机下的棋。玩家和计算机轮流下棋，直到出现胜者或棋盘填满。胜者是指在一行、一列或对角线上连续出现五个棋子的一方。
