9. 三子棋
类似于之前的猜数字小游戏，我们需要先把整个游戏的大体结构在主函数中实现出来：
//test.c
#include 接下来，我们需要对游戏内容进行具体地实现：
- 初始化棋盘
棋盘上一开始什么都没有，说明里面放的都是空格
//test.c
#include "game.h"
void game()
{
char board[3][3] = { 0 };
InitBoard(board, 3, 3);
}
在game.h中对函数进行声明
//game.h
//初始化棋盘
void InitBoard(char board[3][3], int row, int col);
这里我们思考一下：如果我们不想玩三子棋，而想玩四子棋，那么我们是不是需要把所有是3的地方全部改成4，这样就太繁琐了，那么要如何解决呢？
//game.h
#define ROW 3
#define COL 3
//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//test.c
#include "game.h"
void game()
{
char board[ROW][COL] = { 0 };
InitBoard(board, ROW, COL);
}
在game.c中对函数进行定义
//game.c
#include "game.h"
//初始化棋盘为空格
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] = ' ';
}
}
}
- 打印棋盘
//test.c
#include "game.h"
void game()
{
char board[ROW][COL] = { 0 };
InitBoard(board, ROW, COL);
//打印棋盘
DisplayBoard(board, ROW, COL);
}
//game.h
#define ROW 3
#define COL 3
//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);
因为在game.c中实现打印棋盘，要引用头文件stdio.h，而test.c中也需要引用stdio.h；同时，test.c和game.c又都引用了game.h，所以我们可以直接在game.h中引用stdio.h
//game.h
#include //game.c
#include "game.h"
//版本一
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]);
}
printf("\n");
}
}
以上打印方法打印出来屏幕上什么也没有，这是因为我们打印的是空格，所以我们还需要加一下分界线
//game.c
#include "game.h"
//版本2
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
//1. 打印数据
printf(" %c | %c | %c \n", board[i][0], board[i][1], board[i][2]);
//2. 打印分割线
if (i < row - 1)
{
printf("---|---|---\n");
}
}
}
以上打印方法不具有普适性，如果改变行和列，打印出来的棋盘就不对了
//game.c
#include "game.h"
//版本3
void DisplayBoard(char board[ROW][COL], int row, int col)
{
int i = 0;
for (i = 0; i < row; i++)
{
//1. 打印数据
int j = 0;
for (j = 0; j < col; j++)
{
printf(" %c ", board[i][j]);
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
//2. 打印分割线
if (i < row - 1)
{
//printf("---|---|---\n");
int j = 0;
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
{
printf("|");
}
}
printf("\n");
}
}
}
- 玩家下棋
//test.c
#include "game.h"
void game()
{
char board[ROW][COL] = { 0 };
InitBoard(board, ROW, COL);
//打印棋盘
DisplayBoard(board, ROW, COL);
//下棋
//玩家下棋
PlayerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);
}
//game.h
#include //game.c
#include "game.h"
void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("玩家下棋>:\n");
while (1)
{
printf("请输入下棋的坐标，中间使用空格>:");
scanf("%d %d", &x, &y);
//坐标合法
if (x >= 1 && x <= row && y >= 1 && y <= col)
{
if (' ' == board[x - 1][y - 1])//可以落子
{
board[x - 1][y - 1] = '*';
break;
}
else
{
printf("坐标被占有，不能落子，重新输入坐标\n");
}
}
else//非法
{
printf("坐标非法，重新输入\n");
}
}
}
- 电脑下棋
我们先让玩家和电脑一直下棋
//test.c
#include "game.h"
void game()
{
char board[ROW][COL] = { 0 };
InitBoard(board, ROW, COL);
//打印棋盘
DisplayBoard(board, ROW, COL);
//下棋
while (1)
{
//玩家下棋
PlayerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);
//电脑下棋
ComputerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);
}
}
int main()
{
srand((unsigned int)time(NULL));
return 0;
}
//game.h
#include //game.c
#include "game.h"
//电脑随机下棋
void ComputerMove(char board[ROW][COL], int row, int col)
{
int x = 0;//0～row-1
int y = 0;//0～col-1
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
玩家赢 - ‘*’
电脑赢 - ‘#’
平局 - ‘Q’
继续 - ‘C’
//test.c
#include "game.h"
void game()
{
char board[ROW][COL] = { 0 };
InitBoard(board, ROW, COL);
//打印棋盘
DisplayBoard(board, ROW, COL);
//下棋
char ret = 0;
while (1)
{
//玩家下棋
PlayerMove(board, ROW, COL);
DisplayBoard(board, ROW, COL);
//判断输赢
ret = IsWin(board, ROW, COL);
