编写此游戏最好新建三个文件:两个源文件,一个头文件
即://test.c 测试游戏的逻辑
//game.c 游戏代码的实现
//game.h 游戏代码的声明(函数声明、符号定义)
先说下编译此游戏的关键步骤思路:
1、创建一个二维数组(棋盘),并进行初始化
2、打印棋盘形状
3、玩家下棋
4、判断输赢并打印棋盘
4、电脑下棋
5、判断输赢并打印棋盘
……(以此循环,直到分出胜负或平局)
其中有五个关键的自定义函数:
初始化棋盘的函数、打印棋盘的函数、玩家下棋的函数、电脑下棋的函数、判断输赢的函数
如下:
//初始化棋盘
void initialize_chess(char chess[row][col], int row1, int col1);
//打印棋盘
void print_chess(char chess[row][col], int row1, int col1);
//玩家下棋
void player_chess(char chess[row][col],int row1,int col1);
//判断输赢
char is_win(char chess[row][col], int row1, int col1);
//电脑下棋
void computer_chess(char chess[row][col], int row1, int col1);
下面进入正题:
首先写出主函数并打印菜单:
主函数内容:
int main()
{
int input = 0;
srand((unsigned)time(NULL));//设置随机数的生成起点
do
{
menu();
printf("请选择:>");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("游戏已退出\n");
break;
default:
printf("选择错误,请重新选择\n");
break;
}
} while(input);
return 0;
}
打印菜单:
void menu()
{
printf("*****************************\n");
printf("************1.enter**********\n");
printf("************0.exit **********\n");
printf("*****************************\n");
}
函数game是自定义的三子棋游戏实现函数,也是整个三子棋游戏代码的主体,函数内的主要代码内容编写如下:
char ret = 0;
char chess[row][col] = { 0 };
//初始化棋盘
initialize_chess(chess, row, col);
//打印棋盘
print_chess(chess, row, col);
初始化棋盘函数:
void initialize_chess(char chess[row][col], int row1, int col1)
{
int i = 0;
int j = 0;
for (i = 0; i < row1; i++)
{
for (j = 0; j < col1; j++)
{
chess[i][j] = ' ';
}
}
}
打印棋盘函数:
void print_chess(char chess[row][col], int row1, int col1)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i ++ )
{
//打印数据
for (j = 0; j < col; j++)
{
printf(" %c ", chess[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
//打印分割线
if (i < row - 1)
{
for (j = 0; j < col ; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
printf("\n");
}
}
}
然后便开始编写玩家与电脑博弈的while循环:
//玩家和电脑下棋博弈
while (1)
{
//玩家下棋
player_chess(chess, row, col);
//判断输赢
ret = is_win(chess, row, col);
if (ret != 'C')
break;
print_chess(chess, row, col);
//电脑下棋
computer_chess(chess, row, col);
//判断输赢
ret = is_win(chess, row, col);
if (ret != 'C')
break;
print_chess(chess, row, col);
}
其中的玩家下棋函数:
void player_chess(char chess[row][col], int row1, int col1)
{
int m = 0;
int n = 0;
printf("玩家下棋:>\n");
while (1)
{
printf("请输入坐标:>");
scanf("%d,%d", &m, &n);
//判断输入坐标是否合法
if (m >= 1 && m <= row && n >= 1 && n <= col)
{
if (chess[m - 1][n - 1] == ' ')
{
chess[m - 1][n - 1] = '*';
break;
}
else
printf("坐标已占用,请重新输入\n");
}
else
printf("输入坐标非法,请重新输入\n");
}
}
电脑下棋函数:
void computer_chess(char chess[row][col], int row1, int col1)
{
printf("电脑下棋:>\n");
int m = 0;
int n = 0;
while (1)
{
m = rand() % row;//0~2
n = rand() % col;//0~2
if (chess[m][n] == ' ')
{
chess[m][n] = '#';
break;
}
}
}
判断输赢函数:
int draw(char chess[row][col], int row1, int col1)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i++)
{
for (j = 0; j < col; j++)
{
if (chess[i][j])//有空格即还未平局
return 0;
}
}
return 1;//满格了即平局
}
char is_win(char chess[row][col], int row1, int col1)
{
//行方向棋下满
int i = 0;
for (i = 0; i < row; i++)
{
if (chess[i][0] == chess[i][1] && chess[i][1] == chess[i][2] && chess[i][0] != ' ')
return chess[i][0];
}
//列方向棋下满
int j = 0;
for (j = 0; j < col; j++)
{
if (chess[0][j] == chess[1][j] && chess[1][j] == chess[2][j] && chess[0][j] != ' ')
return chess[0][j];
}
//对角线方向棋下满
if (chess[0][0] == chess[1][1] && chess[1][1] == chess[2][2] && chess[0][0] != ' ')
return chess[0][0];
if (chess[0][2] == chess[1][1] && chess[1][1] == chess[2][0] && chess[0][2] != ' ')
return chess[0][2];
//平局(棋下满还未出胜负)
if (draw(chess, row, col))
return 'D';
//游戏继续
return 'C';
}
前面已经说明了步骤思路,这里奉上源代码更直观清晰:
test.c源文件:
#include"game.h"
void menu()
{
printf("*****************************\n");
printf("************1.enter**********\n");
printf("************0.exit **********\n");
printf("*****************************\n");
}
void game()
{
char ret = 0;
char chess[row][col] = { 0 };
//初始化棋盘
initialize_chess(chess, row, col);
//打印棋盘
print_chess(chess, row, col);
//玩家和电脑下棋博弈
while (1)
{
//玩家下棋
player_chess(chess, row, col);
//判断输赢
ret = is_win(chess, row, col);
if (ret != 'C')
break;
print_chess(chess, row, col);
//电脑下棋
computer_chess(chess, row, col);
//判断输赢
ret = is_win(chess, row, col);
if (ret != 'C')
break;
print_chess(chess, row, col);
}
if (ret == '*')
printf("玩家赢\n");
else if (ret == '#')
printf("电脑赢\n");
else
printf("平局\n");
print_chess(chess, row, col);
}
int main()
{
int input = 0;
srand((unsigned)time(NULL));//设置随机数的生成起点
do
{
menu();
printf("请选择:>");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("游戏已退出\n");
break;
default:
printf("选择错误,请重新选择\n");
break;
}
} while(input);
return 0;
}
game.c源文件:

}
void print_chess(char chess[row][col], int row1, int col1)
{
int i = 0;
int j = 0;
for (i = 0; i < row; i ++ )
{
//打印数据
for (j = 0; j < col; j++)
{
printf(" %c ", chess[i][j]);

break;
}
else

return chess[0][j];
}
//对角线方向棋下满
if (chess[0][0] == chess[1][1] && chess[1][1] == chess[2][2] && chess[0][0] != ' ')
return chess[0][0];
if (chess[0][2] == chess[1][1] && chess[1][1] == chess[2][0] && chess[0][2] != ' ')
return chess[0][2];
//平局(棋下满还未出胜负)
if (draw(chess, row, col))
return 'D';
//游戏继续

}
void computer_chess(char chess[row][col], int row1, int col1)
{

int m = 0;

while (1)
{
m = rand() % row;//0~2
n = rand() % col;//0~2
if (chess[m][n] == ' ')
{
chess[m][n] = '#';
break;
}
}
}
game.h头文件:
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define row 3
#define col 3
//初始化棋盘
void initialize_chess(char chess[row][col], int row1, int col1);
//打印棋盘
void print_chess(char chess[row][col], int row1, int col1);
//玩家下棋
void player_chess(char chess[row][col],int row1,int col1);
//判断输赢
char is_win(char chess[row][col], int row1, int col1);
//电脑下棋
void computer_chess(char chess[row][col], int row1, int col1);
细节说明:
1、直接在源文件中引用#include"game.h"会更方便
2、电脑下棋是随机下棋,srand((unsigned)time(NULL))语句是用来生成随机数的起始位置的,要知道rand的用法
