在用C语言实现三子棋小游戏之前，我们应当了解三子棋的游戏规则：在九宫格棋盘上，哪一方三个棋子连成一线（一行或一列或对角线）即判定哪一方胜利。
以下为源代码：
1.首先打印出菜单。

void menu()
{
printf("**********************************\n");
printf("**********************************\n");
printf("***** 0.play *************\n");
printf("***** 1.exit *************\n");
printf("**********************************\n");
}
menu();
do
{
printf("请输入要选的的选项: ");
scanf("%d",&input);
switch (input)
{
case 0:
game();
break;
case 1:
printf("退出游戏");
break;
default:
printf("请输入要选的选项:\n");
break;
}
} while (input);
|
2.创建一个二维数组board用来储存三子棋的元素，并对其进行初始化。

void Initboard(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++)
{
board[i][j] = ' ';
}
}
}
|
3.打印九宫格棋盘。

void Displayboard(char board[ROW][COL], int row, int col) //打印棋盘
{
int i;
int j;
for (i = 0; i < row; i++)
{
for (j = 0; j < col ; j++)
{
printf(" %c ", board[i][j]);
if (j == col - 1)
continue;
printf("|");
}
printf("\n");
if (i < row - 1)
printf("-----------\n");
}
}
|
4.使用Playermove和Computermove函数来对board数组进行更改，模拟玩家和电脑落子情况。

void Playermove(char board[ROW][COL]) //玩家输入坐标
{
while (1)
{
int x = 0;
int y = 0;
printf("请玩家输入坐标");
scanf_s("%d %d", &x, &y);
if (x <= ROW && x >= 1 && y <= COL && y >= 1) //判断输入的坐标是否越界
{
if (board[x - 1][y - 1] == ' ') //输入的坐标必须为空才可以落子
{
board[x - 1][y - 1] = '*';
break;
}
else
printf("坐标被占用，请重新输入\n");
}
else
printf("坐标有误，请重新输入\n");
}
}
void Computermove(char board[ROW][COL]) //电脑输入坐标
{
int x = 0;
int y = 0;
while (1)
{
x = rand() % 3; //使用rand函数生成随机数并取余得到电脑落子坐标
y = rand() % 3;
if (board[x][y] == ' ')
{
printf("电脑输入坐标%d %d\n", x+1, y+1);
board[x][y] = '#';
break; //打印后跳出循环
}
}
}
|
5.玩家和电脑每落一次子，就要进行一次判断是否获胜，根据返回值来进行判断游戏结果。

int Iswin(char board[ROW][COL], int row, int col) //判断谁获胜
{
int i;
int j;
//1为玩家获胜 0为电脑获胜 2为平局
for (i = 0; i < row; i++)
{
if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] == '*') //判断同一行是否相等
return 1;
else if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] == '#')
return 0;
}
for (j = 0; j < col; j++)
{
if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] == '*') //判断同一列是否相等
return 1;
else if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] == '#')
return 0;
}
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] == '*') //判断左对角线是否相等
return 1;
else if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] == '#')
return 0;
if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] == '*') //判断右对角线是否相等
return 1;
else if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] == '#')
return 0;
if (Full(board, ROW, COL)) //判断是否平局
return 2;
return 3; //返回3为继续进行游戏
}
