c语言五子棋源代码easyx

以下是一个简单的 C语言五子棋程序的源代码，使用了 EasyX 图形库：

#include <graphics.h>

#define BOARD_SIZE 15
#define PIECE_SIZE 30
#define MARGIN_SIZE 40

int board[BOARD_SIZE][BOARD_SIZE] = {0};
int curPlayer = 1; // 1 for black, 2 for white

void drawBoard()
{
    setlinecolor(BLACK);
    for(int i = 0; i <= BOARD_SIZE; i++)
    {
        line(MARGIN_SIZE, MARGIN_SIZE + i * PIECE_SIZE, MARGIN_SIZE + BOARD_SIZE * PIECE_SIZE, MARGIN_SIZE + i * PIECE_SIZE);
        line(MARGIN_SIZE + i * PIECE_SIZE, MARGIN_SIZE, MARGIN_SIZE + i * PIECE_SIZE, MARGIN_SIZE + BOARD_SIZE * PIECE_SIZE);
    }
}

void drawPiece(int x, int y, int player)
{
    setfillcolor(player == 1 ? BLACK : WHITE);
    solidcircle(MARGIN_SIZE + x * PIECE_SIZE, MARGIN_SIZE + y * PIECE_SIZE, PIECE_SIZE / 2);
}

bool isValidPos(int x, int y)
{
    if(x < 0 || x >= BOARD_SIZE || y < 0 || y >= BOARD_SIZE)
        return false;
    if(board[x][y] != 0)
        return false;
    return true;
}

bool checkGameOver(int x, int y)
{
    int dx[] = {1, 1, 0, -1}, dy[] = {0, 1, 1, 1};
    for(int i = 0; i < 4; i++)
    {
        int cnt = 1;
        for(int j = 1; j <= 4; j++)
        {
            int nx = x + dx[i] * j, ny = y + dy[i] * j;
            if(isValidPos(nx, ny) && board[nx][ny] == curPlayer)
                cnt++;
            else
                break;
        }
        for(int j = 1; j <= 4; j++)
        {
            int nx = x - dx[i] * j, ny = y - dy[i] * j;
            if(isValidPos(nx, ny) && board[nx][ny] == curPlayer)
                cnt++;
            else
                break;
        }
        if(cnt >= 5)
            return true;
    }
    return false;
}

int main()
{
    initgraph(640, 640);
    drawBoard();
    while(true)
    {
        MOUSEMSG msg = GetMouseMsg();
        if(msg.uMsg == WM_LBUTTONDOWN)
        {
            int x = (msg.x - MARGIN_SIZE + PIECE_SIZE / 2) / PIECE_SIZE,
                y = (msg.y - MARGIN_SIZE + PIECE_SIZE / 2) / PIECE_SIZE;
            if(!isValidPos(x, y))
                continue;
            drawPiece(x, y, curPlayer);
            board[x][y] = curPlayer;
            if(checkGameOver(x, y))
            {
                outtextxy(50, 300, curPlayer == 1 ? "Black wins!" : "White wins!");
                while(true)
                {
                    MOUSEMSG msg = GetMouseMsg();
                    if(msg.uMsg == WM_LBUTTONDOWN)
                        return 0;
                }
            }
            curPlayer = curPlayer == 1 ? 2 : 1;
        }
    }
    closegraph();
    return 0;
}

这是一个非常简单的五子棋程序，只有基本的下棋、判断胜负等功能。如果需要更复杂的 AI 策略，可以考虑使用博弈树等算法。
