C++11 thread类多线程编程

using namespace std;


mutex mu;  //线程互斥对象

int totalNum = 100;

void thread01()
{
    while (totalNum > 0)
    {
        mu.lock(); //同步数据锁
        cout << totalNum << endl;
        totalNum--;
        Sleep(100);
        mu.unlock();  //解除锁定
    }
}
void thread02()
{
    while (totalNum > 0)
    {
        mu.lock();
        cout << totalNum << endl;
        totalNum--;
        Sleep(100);
        mu.unlock();
    }

//两个线程买票，到哪个线程，锁住，totalNum票总数减1，解锁
