一.创建项目
首先创建test.c game.c game.h三个文件.
test.c里放着三子棋的实现过程
game.c里放着实现游戏函数的定义
game.h里放着常量、game.c里函数的声明
二.开始编写
第一步：打印菜单
void menu()
{
printf("########################\n");
printf("###### 0.exit ######\n");
printf("###### 1.play ######\n");
printf("########################\n");
}
int main()
{
int input = 0;
srand((unsigned int)time(NULL));
do
{
menu();
printf("请选择:>");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏\n");
break;
default:
printf("输入错误，请重新输入\n");
break;
}
} while (input);
return 0;
}第二步:
game()函数的实现:
首先要在game.h头文件中定义常量，方便后续修改
#define ROW 3
#define COL 3
然后再game()函数中先创建一个二维数组用来存放下棋的数据
//存放下棋的数据
char board[ROW][COL] = { 0 };接着把棋盘初始化，创建一个初始化函数，在game.c里实现函数功能
//初始化棋盘
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] = ' ';
}
}
}
打印函数
//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
int j = 0;
for (i = 0; i < ROW; i++)
{
//打印数据
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (i < col - 1)
{
printf("|");
}
}
printf("\n");
}
}
}
玩家下棋
void PlayerBoard(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
while (1)
{
printf("玩家下棋:>");
scanf("%d %d", &x, &y);
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (board[x-1][y-1] == ' ')
{
board[x - 1][y - 1] = '*';
break;
}
else
{
printf("该坐标被占用，请重新输入\n");
}
}
else
{
printf("坐标非法，请重新输入\n");
}
}
}
电脑下棋
void ComputerBoard(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("电脑下棋:>\n");
while (1)
{
x = rand() % row;
y = rand() % col;
if (board[x][y] == ' ')
{
board[x][y] = '#';
break;
}
}
}
判断输赢
static int if_full(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;
}
//
char is_win(char board[ROW][COL], int row, int col)
{
int i = 0;
//判断行
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];
}
}
//判断列
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];
}
}
//判断对角线
if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
{
return board[1][1];
}
if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
{
return board[1][1];
}
//判断平局
if (if_full(board, ROW, COL) == 1)
{
return 'Q';
}
return 'C';
}
