C语言五子棋玩家交替下棋示例

以下是一个C语言的五子棋玩家交替下棋的示例：

#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 isWin() {
    // 检查行
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE - 4; j++) {
            if (board[i][j] != ' ' && board[i][j] == board[i][j+1] && board[i][j] == board[i][j+2] && board[i][j] == board[i][j+3] && board[i][j] == board[i][j+4]) {
                return 1;
            }
        }
    }

                return 1;
            }
        }

                return 1;
            }
        }
    }
    
    // 检查副对角线
    for (int i = 0; i < SIZE - 4; i++) {

        }
    }

}
