孙鑫VC++第15章多线程售票，最前边的票（本例为100，有时是99），卖出两张，怎么解决?
如题。Win32 Console Application类型的工程，添加的C++源文件：
#include <windows.h>
#include <iostream.h>
DWORD WINAPI Fun1Proc(
LPVOID lpParameter // thread data
);
DWORD WINAPI Fun2Proc(
LPVOID lpParameter // thread data
);
int index=0;
int tickets=100;
void main()
{
HANDLE hThread1;
HANDLE hThread2;
hThread1=CreateThread(NULL,0,Fun1Proc,NULL,0,NULL);
hThread2=CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);
CloseHandle(hThread1);
CloseHandle(hThread2);
Sleep(4000);
}
DWORD WINAPI Fun2Proc(
LPVOID lpParameter // thread data
)
{
while(TRUE)
{
if(tickets>0)
{
cout<<"thread2 sell ticket : "<<tickets--<<endl;
}
else
break;
}
return 0;
}
DWORD WINAPI Fun1Proc(
LPVOID lpParameter // thread data
)
{
while(TRUE)
{
if(tickets>0)
{
cout<<"thread1 sell ticket : "<<tickets--<<endl;
}
else
break;
}
return 0;
}
