用c语言写一个五子棋

以下是一个简单的五子棋游戏的 C 语言代码：

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

#define ROW 15
#define COL 15

void display_board(char board[][COL]);
int check_win(char board[][COL], int row, int col, char ch);

int main()
{
    char board[ROW][COL] = {0};
    char player = 'X';
    int row, col;

    printf("Welcome to Five in a Row game!\n");

    while (1) {
        display_board(board);
        printf("\nPlayer %c's turn, enter row and column: ", player);
        scanf("%d%d", &row, &col);

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

        if (board[row-1][col-1] != 0) {
            printf("This position is already occupied, please try again.\n");
            continue;
        }

        board[row-1][col-1] = player;
        if (check_win(board, row-1, col-1, player)) {
            display_board(board);
            printf("\nPlayer %c wins!\n", player);
            break;
        }

        if (player == 'X')
            player = 'O';
        else
            player = 'X';
    }

    return 0;
}

void display_board(char board[][COL])
{
    int i, j;

    printf("   ");
    for (i = 1; i <= COL; i++)
        printf("%2d ", i);
    printf("\n");

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

int check_win(char board[][COL], int row, int col, char ch)
{
    int i, j, count;

    // check row
    count = 0;
    for (i = col-4; i <= col+4; i++) {
        if (i < 0 || i >= COL)
            continue;
        if (board[row][i] == ch)
            count++;
        else
            count = 0;
        if (count == 5)
            return 1;
    }

    // check column
    count = 0;
    for (i = row-4; i <= row+4; i++) {
        if (i < 0 || i >= ROW)
            continue;
        if (board[i][col] == ch)
            count++;
        else
            count = 0;
        if (count == 5)
            return 1;
    }

    // check diagonal
    count = 0;
    for (i = row-4, j = col-4; i <= row+4 && j <= col+4; i++, j++) {
        if (i < 0 || i >= ROW || j < 0 || j >= COL)
            continue;
        if (board[i][j] == ch)
            count++;
        else
            count = 0;
        if (count == 5)
            return 1;
    }

    // check another diagonal
    count = 0;
    for (i = row-4, j = col+4; i <= row+4 && j >= col-4; i++, j--) {
        if (i < 0 || i >= ROW || j < 0 || j >= COL)
            continue;
        if (board[i][j] == ch)
            count++;
        else
            count = 0;
        if (count == 5)
            return 1;
    }

    return 0;
}

这个程序提供了一个简单的五子棋游戏界面，并且可以检测出胜利者。你可以在此基础上进行修改，添加更多的功能或者改进游戏体验。
