前言
三子棋是黑白棋的一种。三子棋是一种民间传统游戏，又叫九宫棋、圈圈叉叉、一条龙、井字棋等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。但是，有很多时候会出现和棋的情况。
多文件形式
在实现游戏的首先，需要创建test.c game.c game.h三个文件。
test.c主要进行游戏的测试。
game.c主要进行游戏内部一些函数的具体实现。
game.h主要是一些声明，宏定义。
游戏逻辑
1、打印一个游戏的简易菜单。
2、初始化棋盘。
3、打印棋盘。
4、玩家下棋（键盘输入坐标） 打印棋盘，判断输赢。
5、电脑下棋（随机坐标） 打印棋盘，判断输赢。
游戏实现
1.打印菜单
在屏幕打印一个简易菜单，提示玩家选择。
void menu()
{
printf("**************************
");
printf("******** 1.play ********
");
printf("******** 0.exit ********
");
printf("**************************
");
}
2.初始化棋盘
将3x3的数组初始化为空格。
void InitBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col; j++)
{
board[i][j] = " ";
}
}
}
3.打印棋盘
在屏幕打印当前棋盘，让玩家选择下一步所要走哪一步。
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
int j = 0;
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
printf("|");
}
printf("
");
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
}
printf("
");
}
}
4.玩家下棋
玩家在键盘上输入坐标，所输入的合法范围是1<=x,y<=3，根据玩家所输入将对应数组赋值为星号"*"。
void PlayerMove(char board[ROW][COL], int row, int col)
{
printf("玩家走:>
");
int x = 0;
int y = 0;
while (1)
{
scanf("%d%d", &x, &y);
if (x >= 1 && x <= 3 && y >= 1 && y <= 3)
{
if (board[x - 1][y - 1] == " ")
{
board[x - 1][y - 1] = "*";
break;
}
else
{
printf("坐标被占用，请重新输入
");
}
}
else
{
printf("下标越界，请重新输入
");
}
}
}
5.电脑下棋
生成随机数，在所对应数组赋值为井号‘#"。
void ComputerMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑走:>
");
x = rand() % row;
y = rand() % col;
while (1)
{
x = rand() % row;
y = rand() % col;
if (board[x][y] == " ")
{
board[x][y] = "#";
break;
}
}
}
6.判断输赢
1.玩家赢返回星号
2.电脑赢返回井号
3.平局返回P
4.棋盘为满，继续游戏返回C
char Iswin(char board[ROW][COL], int row, int col)
{
int i = 0;
//行
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != " ")
{
return board[i][1];
}
}
//列
for (i = 0; i < col; i++)
{
if (board[0][i] == board[1][i] && board[1][i] == board[2][i] && board[1][i] != " ")
{
return board[1][i];
}
}
//对角线
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != " ")
{
return board[1][1];
}
if (board[2][0] == board[1][1] && board[1][1] == board[0][2] && board[1][1] != " ")
{
return board[1][1];
}
if (IsFull(board, ROW, COL))
{
return "P";
}
return "C";
}
7.判断棋盘是否满
int IsFull(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
if (board[i][j] == " ")
return 0;
}
}
return 1;
}
具体代码
test.c
#include "game.h"
void menu()
{
printf("**************************
");
printf("******** 1.play ********
");
printf("******** 0.exit ********
");
printf("**************************

}
void game()
{
char board[ROW][COL];
//初始化棋盘
InitBoard(board, ROW, COL);
//打印棋盘
