c语言实现五子棋代码

以下是一个简单的C语言实现五子棋的代码示例：

#include <stdio.h>

#define SIZE 15

char board[SIZE][SIZE]; // 棋盘

void initBoard() {
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            board[i][j] = ' ';
        }
    }
}

void printBoard() {
    printf("  ");
    for (int i = 0; i < SIZE; i++) {
        printf("%2d", i);
    }
    printf("\n");
    for (int i = 0; i < SIZE; i++) {
        printf("%2d", i);
        for (int j = 0; j < SIZE; j++) {
            printf(" %c", board[i][j]);
        }
        printf("\n");
    }
}

int checkWin(int row, int col, char player) {
    int count = 0;
    int i, j;

    // 横向检查
    for (i = col - 4; i <= col; i++) {
        if (i >= 0 && i + 4 < SIZE) {
            count = 0;
            for (j = i; j <= i + 4; j++) {
                if (board[row][j] == player) {
                    count++;
                }
            }
            if (count == 5) {
                return 1;
            }
        }
    }

    // 纵向检查
    for (i = row - 4; i <= row; i++) {
        if (i >= 0 && i + 4 < SIZE) {
            count = 0;
            for (j = i; j <= i + 4; j++) {
                if (board[j][col] == player) {

                }
            }
            if (count == 5) {
                return 1;
            }
        }
    }

    // 左上到右下斜向检查
    for (i = row - 4, j = col - 4; i <= row && j <= col; i++, j++) {
        if (i >= 0 && i + 4 < SIZE && j >= 0 && j + 4 < SIZE) {
            count = 0;
            for (int k = 0; k < 5; k++) {
                if (board[i + k][j + k] == player) {
                    count++;
                }
            }
            if (count == 5) {
                return 1;
            }
        }
    }

    // 左下到右上斜向检查
    for (i = row + 4, j = col - 4; i >= row && j <= col; i--, j++) {
        if (i >= 0 && i - 4 < SIZE && j >= 0 && j + 4 < SIZE) {
            count = 0;
            for (int k = 0; k < 5; k++) {
                if (board[i - k][j + k] == player) {
                    count++;
                }
            }
            if (count == 5) {
                return 1;
            }
        }
    }

    return 0;

int main() {
    int row, col;
