用c语言编写五子棋小游戏

好的，下面是一个简单的五子棋小游戏的C语言代码，包含基本的游戏逻辑和界面：

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

#define BOARD_SIZE 15
#define PLAYER1 'X'
#define PLAYER2 'O'

char board[BOARD_SIZE][BOARD_SIZE];

void init_board() {
    int i, j;
    for (i = 0; i < BOARD_SIZE; i++) {
        for (j = 0; j < BOARD_SIZE; j++) {
            board[i][j] = '+';
        }
    }
}

void display_board() {
    int i, j;
    printf("  ");
    for (i = 0; i < BOARD_SIZE; i++) {
        printf("%c ", 'A' + i);
    }
    printf("\n");

    for (i = 0; i < BOARD_SIZE; i++) {
        printf("%2d", i+1);
        for (j = 0; j < BOARD_SIZE; j++) {
            printf("%c ", board[i][j]);
        }
        printf("\n");
    }
}

int check_win(int row, int col, char player) {
    int i, j;
    int count;

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

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

    // 检查左上到右下的对角线
    count = 0;
    for (i = row - 4, j = col - 4; i <= row && j <= col; i++, j++) {
        if (i >= 0 && i + 4 < BOARD_SIZE && j >= 0 && j + 4 < BOARD_SIZE) {
            for (int k = 0; k < 5; k++) {
                if (board[i+k][j+k] == player) {
                    count++;
                }
            }
            if (count == 5) {
                return 1;
            }
            count = 0;
        }
    }

    // 检查左下到右上的对角线
    count = 0;
    for (i = row + 4, j = col - 4; i >= row && j <= col; i--, j++) {
        if (i >= 0 && i - 4 < BOARD_SIZE && j >= 0 && j + 4 < BOARD_SIZE) {
            for (int k = 0; k < 5; k++) {
                if (board[i-k][j+k] == player) {
                    count++;
                }
            }
            if (count == 5) {
                return 1;
            }
            count = 0;
        }
    }

    return 0;
}

void play_game() {
    int row, col;
    char player = PLAYER1;
    while (1) {
        printf("Player %c's turn:\n", player);
        printf("Enter row (1-%d) and column (A-%c): ", BOARD_SIZE, 'A' + BOARD_SIZE - 1);
        scanf("%d %c", &row, &col);
        row--;
        col -= 'A';

        if (row < 0 || row >= BOARD_SIZE || col < 0 || col >= BOARD_SIZE || board[row][col] != '+') {
            printf("Invalid move!\n");
        } else {
            board[row][col] = player;
            display_board();
            if (check_win(row, col, player)) {
                printf("Player %c wins!\n", player);
                break;
            }
            player = (player == PLAYER1) ? PLAYER2 : PLAYER1;
        }
    }
}

int main() {
    init_board();
    display_board();
    play_game();
    return 0;
}

这个代码实现了一个控制台界面的五子棋小游戏，玩家可以通过输入行和列来下棋，程序会检查胜负并输出结果。由于时间和精力有限，这个代码仅实现了最基本的游戏逻辑，还有很多方面可以改进，比如增加AI、优化算法等等。
