用C语言写一个五子棋游戏在linux上运行

好的，以下是一个简单的五子棋游戏的C语言实现，可以在Linux系统上运行。代码注释中有详细的解释。

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

#define ROW 15
#define COL 15

char board[ROW][COL]; // 棋盘
char player = 'X'; // 先手玩家
char winner = '\0'; // 胜者

void init_board(); // 初始化棋盘
void display_board(); // 显示棋盘
void play_game(); // 开始游戏
int is_valid_input(int row, int col); // 判断输入是否合法
int is_win(); // 判断是否胜利

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

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

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

void play_game()
{
    int row, col;
    printf("Player %c goes first.\n", player);
    while (1) {
        printf("Player %c's turn. Enter row and column: ", player);
        scanf("%d %d", &row, &col);
        if (!is_valid_input(row, col)) {
            printf("Invalid input. Try again.\n");
            continue;
        }
        board[row][col] = player;
        display_board();
        if (is_win()) {
            printf("Player %c wins!\n", winner);
            break;
        }
        player = player == 'X' ? 'O' : 'X'; // 切换玩家
    }
}

int is_valid_input(int row, int col)
{
    // 判断输入是否在棋盘范围内，并且该位置是否为空
    if (row < 0 || row >= ROW || col < 0 || col >= COL || board[row][col] != '+') {
        return 0;
    }
    return 1;
}

int is_win()
{
    int i, j, k;
    // 判断横向是否有五个相同颜色的棋子
    for (i = 0; i < ROW; i++) {
        for (j = 0; j < COL - 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]) {
                winner = board[i][j];
                return 1;
            }
        }
    }
    // 判断纵向是否有五个相同颜色的棋子
    for (i = 0; i < ROW - 4; i++) {
        for (j = 0; j < COL; j++) {
            if (board[i][j] != '+' && board[i][j] == board[i+1][j] && board[i][j] == board[i+2][j] && board[i][j] == board[i+3][j] && board[i][j] == board[i+4][j]) {
                winner = board[i][j];
                return 1;
            }
        }
    }
    // 判断左斜向是否有五个相同颜色的棋子
    for (i = 0; i < ROW - 4; i++) {
        for (j = 0; j < COL - 4; j++) {
            if (board[i][j] != '+' && board[i][j] == board[i+1][j+1] && board[i][j] == board[i+2][j+2] && board[i][j] == board[i+3][j+3] && board[i][j] == board[i+4][j+4]) {
                winner = board[i][j];
                return 1;
            }
        }
    }
    // 判断右斜向是否有五个相同颜色的棋子
    for (i = 0; i < ROW - 4; i++) {
        for (j = 4; j < COL; j++) {
            if (board[i][j] != '+' && board[i][j] == board[i+1][j-1] && board[i][j] == board[i+2][j-2] && board[i][j] == board[i+3][j-3] && board[i][j] == board[i+4][j-4]) {
                winner = board[i][j];
                return 1;
            }
        }
    }
    return 0;
}

您可以将以上代码保存为一个名为`gobang.c`的文件，并使用gcc编译器进行编译，命令如下：

gcc gobang.c -o gobang

编译完成后，运行程序即可开始玩五子棋游戏。
