用c++写一个五子棋项目

好的，以下是一个简单的五子棋项目的C代码：

#include <stdio.h>
#include <stdbool.h>

#define ROWS 15
#define COLS 15

char board[ROWS][COLS];

void initialize_board() {
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            board[i][j] = '-';
        }
    }
}

void print_board() {
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            printf("%c ", board[i][j]);
        }
        printf("\n");
    }
}

bool is_valid_move(int row, int col) {
    if (row >= 0 && row < ROWS && col >= 0 && col < COLS && board[row][col] == '-') {
        return true;
    } else {
        return false;
    }
}

bool is_win(char symbol) {
    for (int i = 0; i < ROWS; i++) {
        for (int j = 0; j < COLS; j++) {
            if (board[i][j] == symbol) {
                if (i + 4 < ROWS && board[i+1][j] == symbol && board[i+2][j] == symbol && board[i+3][j] == symbol && board[i+4][j] == symbol) {
                    return true;
                }
                if (j + 4 < COLS && board[i][j+1] == symbol && board[i][j+2] == symbol && board[i][j+3] == symbol && board[i][j+4] == symbol) {
                    return true;
                }
                if (i + 4 < ROWS && j + 4 < COLS && board[i+1][j+1] == symbol && board[i+2][j+2] == symbol && board[i+3][j+3] == symbol && board[i+4][j+4] == symbol) {
                    return true;
                }
                if (i + 4 < ROWS && j - 4 >= 0 && board[i+1][j-1] == symbol && board[i+2][j-2] == symbol && board[i+3][j-3] == symbol && board[i+4][j-4] == symbol) {
                    return true;
                }
            }
        }
    }
    return false;
}

int main() {
    initialize_board();
    print_board();

    char player1 = 'X';
    char player2 = 'O';

    char current_player = player1;

    int row, col;

    while (true) {
        printf("Current player: %c\n", current_player);
        printf("Enter row and column numbers (e.g. 3 4): ");
        scanf("%d %d", &row, &col);

        if (!is_valid_move(row, col)) {
            printf("Invalid move!\n");
            continue;
        }

        board[row][col] = current_player;
        print_board();

        if (is_win(current_player)) {
            printf("Player %c wins!\n", current_player);
            break;
        }

        if (current_player == player1) {
            current_player = player2;
        } else {
            current_player = player1;
        }
    }

    return 0;
}

这个程序实现一个简单的五子棋游戏，实现了下棋、判断是否胜利、交替下棋等功能。您可以按照自己的需求进行修改和扩展。
