C language games - three chess

The game passes 3 Source file implementation

1. The header file game.h

#pragma once
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define ROW 3  // The number of rows on the chessboard 
#define COL 3  // The number of rows on the chessboard 

// Initialize chessboard

// Print chessboard 
void Displayboard(char board[ROW][COL], int row, int col);

// Players play chess 
void PlayerMove(char board[ROW][COL], int row, int col);

// The computer plays chess 
void ComputerMove(char board[ROW][COL], int row, int col);

// Judgement of winning or losing 
char IsWin(char board[ROW][COL], int row, int col);
