題目：建立兩個線程類比火車站兩個視窗售票程式，視窗售票時間為1秒，兩個視窗不能同時售票

#include<Windows.h>
#include<iostream>
using namespace std;
//這是2個線程類比買火車票的小程式
DWORD WINAPI Fun1Proc(LPVOID lpParameter);//thread data
DWORD WINAPI Fun2Proc(LPVOID lpParameter);//thread data


int index = 0;

int main()
{
HANDLE hThread1;
HANDLE hThread2;
//建立線程

hThread2 = CreateThread(NULL, 0, Fun2Proc, NULL, 0, NULL);
CloseHandle(hThread1);
CloseHandle(hThread2);
//建立互斥對象
hMutex = CreateMutex(NULL, TRUE, "tickets");
if (hMutex)
{
if (ERROR ALREADY EXISTS == GetLastError())
{
cout << "only one instance can run!" << endl;
return 0;
}
}
WaitForSingleObject(hMutex, INFINITE);
ReleaseMutex(hMutex);
ReleaseMutex(hMutex);
Sleep(4000);

//線程1的入口函數

if (tickets > 0)
{

cout << "thread1 sell ticket:" << tickets-- << endl;


}
else
break;
ReleaseMutex(hMutex);
}
return 0;
}


//線程2 的入口函數
