一生产者消费者：

std::mutex mu;
deque<int> q;
condition_variable CR;

void produce()
{
	int count = 10;
	while (count>0)
	{
		unique_lock<mutex> lock(mu);
		cout << " product 生产了" << count << endl;
		q.push_front(count);
		lock.unlock();
		CR.notify_all();
		Sleep(1);
		count--;

	}

}

void consume()
{
	int data = 0;
	while (data!=1)
	{
		unique_lock<mutex> lock(mu);
		CR.wait(lock, [](){return !q.empty(); });
		data = q.back();
		q.pop_back();
		lock.unlock();
		cout << "consumer got a value from product" << data << endl;

	

	}

}


int main()
{
	thread T1(produce);
	thread T2(consume);

	T1.join();
	T2.join();
}

二循环打印ABC

std::mutex mu;


void A()
{

	for (int i = 0; i < 10; i++)
	{
		
		lock_guard<mutex> lock(mu);
		cout << 'A';
		Sleep(10);
	
	}

}

void B()
{

	for (int i = 0; i < 10; i++)
	{
		
		lock_guard<mutex> lock(mu);
		cout << 'B';
		Sleep(10);

	}

}

void C()
{

	for (int i = 0; i < 10; i++)
	{
	
		lock_guard<mutex> lock(mu);
		cout << 'C';
		Sleep(1);
	
	}

}




int main()
{

	
	thread T1(A);
	thread T2(B);
	thread T3(C);
	T1.join();
	T2.join();
	T3.join();

	

}
