Game rules:
Sanziqi is a traditional folk game, also called Jiugongqi, Quanhuanchacha, One Dragon, Tic Tac Toe and so on. Connect the diagonals of the square and place three pawns on opposite sides in turn. As long as your three pawns form a line, the opponent will lose.
The code adopts a modular idea:
game.h module:
store header files and function declarations
#define _CRT_SECURE_NO_WARNINGS 1
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
//全局变量，方便修改后期棋盘的大小
#define COL 3//列
#define ROW 3//行
#define COUNT 3
void menu(void);
void game(void);
void InitBoard(char board[ROW][COL], int row, int col);
void DisplayBoard(char board[ROW][COL], int row, int col);
void PlayerMove(char board[ROW][COL], int row, int col, int arr[]);
void ComMove(char board[ROW][COL], int row, int col, int arr[]);
char Winner(char board[ROW][COL], int row, int col, int arr[]);
int IsFull(char board[ROW][COL], int row, int col);
game.c module:
calls between functions when the game is running,
including: menu printing, board initialization, display of the board, determination of player and computer placement positions, and judgment of winning or losing
#include "game.h"
//打印菜单
void menu()
