看不明白代码，测试了，发现有点问题

//#include <tchar.h>        //在程序中使用 #include <tchar.h> 添加对 TCHAR 的支持。
#include<stdio.h>
#include<string.h>
#include<stdlib.h>    //清屏命令在这里。
#include <windows.h> //延时10毫秒-sleep,gotoxy函数
#include <iostream>
#include <conio.h>       //getch()----不用按回车，就可以输入字符。    
#include <graphics.h>      //EasyX库，所使用的！
