前几行输出比较乱，贴出来看

//前几行输出较混乱，帮忙解决一下

Answer 1

WaitForSingleObject(h0,INFINITE);放到循环里面。

Answer 2

HANDLE hThread1;
    HANDLE hThread2;
    hThread1=CreateThread(NULL,0,Thread1Proc,NULL,0,NULL);
    hThread2=CreateThread(NULL,0,Thread2Proc,NULL,0,NULL);
    CloseHandle(hThread1);//关闭句柄, 此时系统会递减新线程的线程内核对象的使用计数, 当创建的线程
    CloseHandle(hThread2);//执行完毕后, 系统也会递减线程内核对象的使用计数, 计数为0时, 系统释放线程内核对象
   //不是关闭了，为什么还会执行Thread1Proc,Thread2Proc
    hMutex=CreateMutex(NULL,TRUE,NULL); //TRUE表示调用CreateMutex的线程拥有了互斥对象
    WaitForSingleObject(hMutex,INFINITE);//线程多次拥有互斥对象, 主要通过互斥对象内的计数器实现
    ReleaseMutex(hMutex); //申请两次则要释放两次
    ReleaseMutex(hMutex); //谁申请谁释放
    Sleep(1000); //要保证在卖完100张票前，主线程不能退出

Answer 3

哦，第一个问题我明白了，不过上面的问题还是不清楚。不是关闭了，怎么还会执行Thread1Proc,Thread2Proc
