用c语言写一个五子棋游戏

好的，下面是一个简单的五子棋游戏的C语言代码：

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

#define ROWS 15 // 棋盘行数
#define COLS 15 // 棋盘列数

#define PLAYER1 'X' // 玩家1使用的棋子
#define PLAYER2 'O' // 玩家2使用的棋子

char board[ROWS][COLS]; // 棋盘

// 初始化棋盘
void init_board()
{
    memset(board, ' ', sizeof(board));
}

// 打印棋盘
void print_board()
{
    int i, j;

    for (i = 0; i < ROWS; i++) {
        printf(" %d ", i + 1);
        for (j = 0; j < COLS; j++) {
            printf("|%c", board[i][j]);
        }
        printf("|\n");
    }
    printf("   ");
    for (i = 0; i < COLS; i++) {
        printf(" %c", 'a' + i);
    }
    printf("\n");
}

// 判断某一行是否有五子连珠
int check_row(int row, char player)
{
    int i, count = 0;

    for (i = 0; i < COLS; i++) {
        if (board[row][i] == player) {
            count++;
            if (count == 5) {
                return 1;
            }
        } else {
            count = 0;
        }
    }

    return 0;
}

// 判断某一列是否有五子连珠
int check_col(int col, char player)
{
    int i, count = 0;

    for (i = 0; i < ROWS; i++) {
        if (board[i][col] == player) {
            count++;
            if (count == 5) {
                return 1;
            }
        } else {
            count = 0;
        }
    }

    return 0;
}

// 判断从左上到右下的斜线是否有五子连珠
int check_diag1(int row, int col, char player)
{
    int i, count = 0;

    for (i = 0; i < 5; i++) {
        if (row + i >= ROWS || col + i >= COLS) {
            return 0;
        }
        if (board[row + i][col + i] == player) {
            count++;
            if (count == 5) {
                return 1;
            }
        } else {
            count = 0;
        }
    }

    return 0;
}

// 判断从右上到左下的斜线是否有五子连珠
int check_diag2(int row, int col, char player)
{
    int i, count = 0;

    for (i = 0; i < 5; i++) {
        if (row - i < 0 || col + i >= COLS) {
            return 0;
        }
        if (board[row - i][col + i] == player) {
            count++;
            if (count == 5) {
                return 1;
            }
        } else {
            count = 0;
        }
    }

    return 0;
}

// 判断当前玩家是否胜利
int check_win(char player)
{
    int i, j;

    for (i = 0; i < ROWS; i++) {
        // 检查行
        if (check_row(i, player)) {
            return 1;
        }
        // 检查列
        if (check_col(i, player)) {
            return 1;
        }
    }

    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            // 检查左上到右下的斜线
            if (check_diag1(i, j, player)) {
                return 1;
            }
            // 检查右上到左下的斜线
            if (check_diag2(i, j, player)) {
                return 1;
            }
        }
    }

    return 0;
}

// 判断棋盘是否已满
int is_full()
{
    int i, j;

    for (i = 0; i < ROWS; i++) {
        for (j = 0; j < COLS; j++) {
            if (board[i][j] == ' ') {
                return 0;
            }
        }
    }

    return 1;
}

// 玩家下棋
void player_move(char player)
{
    int row, col;

    while (1) {
        printf("Player %c's turn:\n", player);
        printf("Enter row number (1-15): ");
        scanf("%d", &row);
        printf("Enter column letter (a-o): ");
        scanf(" %c", &col);

        if (row < 1 || row > ROWS || col < 'a' || col > 'o') {
            printf("Invalid input, please try again.\n");
            continue;
        }

        if (board[row-1][col-'a'] != ' ') {
            printf("This position is already occupied, please try again.\n");
            continue;
        }

        board[row-1][col-'a'] = player;
        break;
    }
}

// 游戏主循环
void game_loop()
{
    char player = PLAYER1;

    while (!is_full()) {
        print_board();
        player_move(player);
        if (check_win(player)) {
            printf("Player %c wins!\n", player);
            print_board();
            return;
        }
        player = player == PLAYER1 ? PLAYER2 : PLAYER1;
    }

    printf("Game over, it's a tie!\n");
    print_board();
}

int main()
{
    init_board();
    game_loop();
    return 0;
}

这个代码实现了基本的五子棋游戏功能，但是还有很多可以改进的地方，比如可以加上落子提示、悔棋功能、AI对战等等。
