实现思路：
1.代码搭建：
2.框架搭建：
3.菜单功能实现:
4.游戏功能实现:
1.game()函数：
5.主要函数:
1.创建棋盘并初始化：
2.打印棋盘：
3.玩家下棋：
4.电脑下棋：
5.判断输赢：
6.整体代码：
实现思路：
1.代码搭建：
使用的vs2019编译器进行编译
test.c文件实现整个游戏框架,game.c文件实现整个游戏的具体游戏功能,game.h文件实现整个游戏需要的声明和头文件.
2.框架搭建：
让玩家来选择开始游戏,或者退出游戏,为了让玩家玩完一把继续下一把,采用do……while循环
int main()
{
int input = 0;
do
{
menu();
printf("Please select the item you want to select\n");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏\n");
break;
default:
printf("您输入的选择有误,请重新选择\n");
break;
}
} while (input);
}
3.菜单功能实现:
1.创建菜单menuFunctions allow players to make choices
void menu()
{
printf("************************\n");
printf("****** 1.play ******\n");
printf("****** 0.eixt ******\n");
printf("************************\n");
}
4.游戏功能实现:
在game()函数内实现：
1.game()函数：
void game()
{
//创建棋盘
char board[ROW][COL] = { 0 };
//初始化棋盘
init_board(board, ROW, COL);
//打印棋盘
print_board(board, ROW, COL);
char ret = '0';//接受游戏状态
while (1)
{
//man starts playing chess
people_play(board, ROW, COL);
print_board(board, ROW, COL);
//判断输赢
ret = judge_lw(board, ROW, COL);
if (ret != 'C')
break;
//电脑下棋
com_play(board, ROW, COL);
print_board(board, ROW, COL);
ret = judge_lw(board, ROW, COL);
if (ret != 'C')
break;
}
if (ret == '*')
{
printf("玩家赢了\n");
}
else if (ret == '#')
{
printf("电脑赢了\n");
}
else
{
printf("平局\n");
}
}
5.主要函数:
1.创建棋盘并初始化：
本函数init_board（）The main function is to initialize the chessboard,Assign all board spaces to spaces,
void init_board(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] = ' ';
}
}
}
2.打印棋盘：
print_board（）The main function of the function is to print the chessboard and display it on the screen; A printed checkerboard The method is to use two layers of loops to print out the space of the move first（%c）,Then print the outline;
3.玩家下棋：
people_play（）The function is used to make the player play chess ;首先从键盘录入两个坐标,判断坐标的合法性,如果是空格（” “）则赋值"*"(玩家下的棋子);
4.电脑下棋：
com_play（）The function implements the computer to play chess;Computers play chess using random numbers 需要现在main函数先声明 ：srand((unsigned int)time(NULL));
然后再用 rand()函数设置随机数
注：srand rand 的头文件是#include<stdlib.h>
time的头文件是#include<time.h>
5.判断输赢：
judge_lw（）The function is used to determine winning or losing,如果返回"*"则代表玩家赢,返回"#"则代表电脑赢,返回"Q"则代表平局,返回"C"则代表继续
实现IsFullThe function is used to determine a draw
Return if the game is full1 ,不满返回0
6.整体代码：
test.c 文件
#include"game.h"

char ret = '0';//接受游戏状态
while (1)
{
//man starts playing chess
people_play(board, ROW, COL);
print_board(board, ROW, COL);
//判断输赢
ret = judge_lw(board, ROW, COL);

break;

break;
}
