c++编写的多线程售票的例子

#include <windows.h>
#include <iostream.h>

DWORD WINAPI Fun1Proc(LPVOID lpParameter);//线程入口函数
DWORD WINAPI Fun2Proc(LPVOID lpParameter);//线程入口函数
int tickets=100;//总共的票数
HANDLE hMutex;//互斥锁句柄
void main(){
  HANDLE hThread1;
  HANDLE hThread2;
  hThread1=CreateThread(NULL,0,Fun1Proc,NULL,0,NULL);//创建一个线程
  hThread2=CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);//创建一个线程
  CloseHandle(hThread1); //关闭线程句柄
  CloseHandle(hThread2);

  //创建匿名的互斥锁对象
  hMutex=CreateMutex(NULL,FALSE,NULL);
  //cout<<"main thread is running"<<endl;
  Sleep(4000);
}
//线程1的入口函数
DWORD WINAPI Fun1Proc(LPVOID lpParameter){
  //cout<<"thead1 is running"<<endl;
 while(true){
         WaitForSingleObject(hMutex,INFINITE);//获得锁
  if(tickets>0){
   Sleep(1);
    cout<<"thread1 sell ticket:"<<tickets--<<endl;
  }else{
     break; 
  }
    ReleaseMutex(hMutex);//释放锁
 }
   return 0;
}
//线程2的入口函数
DWORD WINAPI Fun2Proc(LPVOID lpParameter){
  //cout<<"thead2 is running"<<endl;
 while(true){
  WaitForSingleObject(hMutex,INFINITE);// 获得锁
  if(tickets>0){
   Sleep(1);
    cout<<"thread2 sell ticket:"<<tickets--<<endl;
  }else{
     break;  
  }
    ReleaseMutex(hMutex);//释放锁
 }
   return 0;
