Use VS make a small game (backgammon)

First, the preparation:

Download Visual Studio (hereinafter using VS2017)
Download Easyx Library: official easyx library download top right Download

Second, the idea of understanding

(This is a simple stand-alone double backgammon)

1, initialization of a 15 * 15 board, the board will empty each position 0 is assigned

2, if a player down a pawn, the value will be placed on the board 1, Player 2 Similarly

Third, the complete code

#include <iostream>
#include<graphics.h>
using namespace std;

int a[15][15] = { 0 }; //定义棋盘的全局变量
MOUSEMSG mouse; //定义鼠标的全局变量

//自定义的子函数
void init();		//初始化界面
void put(int penson, int x, int y); //在二位数组将元素置为非空，相当于放下棋子
void drow_Black(int x, int y);		//画黑棋
void drow_White(int x, int y);		//画白棋
int change(short k);				//将棋盘与二位数组映射，方便判断输赢
void show(int person);				//胜利时显示的界面
bool Check_Win(int person, int x, int y);	//调用各种函数，判断是否胜利
bool Check_LeftAndRight(int person, int x, int y);	//检索棋盘左右是否五颗相连
bool Check_TopAndButton(int person, int x, int y);	//检索棋盘上下是否五颗相连
bool Check_LeftAndDiagonal(int person, int x, int y);	//检索棋盘左斜是否五颗相连
bool Check_RightAndDiagonal(int person, int x, int y);	//检索棋盘右斜是否五颗相连

int main()
{
	//加载画面
	init();
	int x, y;
	int person=1;
	FlushMouseMsgBuffer();// 清空鼠标消息缓冲区
	while (true)

		if (mouse.uMsg == WM_LBUTTONDOWN)	//是否按鼠标左键
		{
			x = change(mouse.x);
			y = change(mouse.y);
			if (x >= 0 && x < 15 && y >= 0 && y < 15)
			{
