C语言五子棋程序代码

五子棋程序是一种经典的人机博弈游戏，C语言编写的五子棋程序可以让我们更好地理解程序设计和算法实现。五子棋程序主要包括以下几个部分：

1. 界面设计：包括棋盘的显示、落子的标识、游戏结果的显示等。
2. 游戏逻辑：包括玩家与电脑的交互、判断胜负、落子的规则等。
3. AI算法：实现电脑落子的策略，可以采用博弈树搜索、最大最小值算法等。

以下是一个简单的C语言五子棋程序示例：

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

#define ROW 15
#define COL 15
#define PLAYER 1
#define COMPUTER 2

int chessboard[ROW][COL] = {0};

void initChessboard()
{
    int i, j;
    for(i=0; i<ROW; i++)
        for(j=0; j<COL; j++)
            chessboard[i][j] = 0;
}

void printChessboard()
{
    int i, j;
    for(i=0; i<ROW; i++)
    {
        for(j=0; j<COL; j++)
        {
            if(chessboard[i][j] == PLAYER)
                printf("O ");
            else if(chessboard[i][j] == COMPUTER)
                printf("X ");
            else
                printf("+ ");
        }
        printf("\n");
    }
}
