#include<windows.h> 
#include<iostream.h> DWORD WINAPI Fun1Proc(LPVOID lpParameter); //声明线程函数1int tickets=100; //初始化车票的数量
HANDLE hMutex; //定义线程互斥对象
void main() 
{ 
HANDLE hThread1; //定义线程hThread1
hThread1=CreateThread(NULL,0,Fun1Proc,NULL,0,NULL); //创建线程hThread1
CloseHandle(hThread1); //关闭线程句柄，
cout<<"main thread is running!"<<endl; 
hMutex=CreateMutex(NULL,FALSE,NULL); //初始化线程互斥对象
while(1) 
{ 
WaitForSingleObject(hMutex,INFINITE); //等待互斥对象
if(tickets>0)//如果车票数量大于0则卖票，车票数量减一
{ 
cout<<"main thread sell tickets:"<<tickets<<endl; 
tickets--; 
} else 
break; //若车票卖光了，则跳出while循环ReleaseMutex(hMutex); //主线程卖出一张票后，释放线程互斥对象
} 
} 
DWORD WINAPI Fun1Proc(LPVOID lpParameter) //定义线程1的处理函数
{ 
cout<<" thread1 is running!"<<endl; 
while(1) 
{ 
WaitForSingleObject(hMutex,INFINITE); //等待线程互斥对象
if(tickets>0) //若车票没卖完，则卖票，车票数减一
{ cout<<"thread1 sell tickets:"<<tickets<<endl; 
tickets--; 
} else 
break; //否则跳出while循环
ReleaseMutex(hMutex); //卖票成功，释放线程互斥对象
} 
return 0;
