生产者消费者问题

◦ 一个大小为3的缓冲区，初始为空

◦ 2个生产者



– 随机等待一段时间，往缓冲区添加数据，



– 若缓冲区已满，等待消费者取走数据后再添加



– 重复6次

◦ 3个消费者



– 随机等待一段时间，从缓冲区读取数据



– 若缓冲区为空，等待生产者添加数据后再读取



– 重复4次



说明：

◦ 显示每次添加和读取数据的时间及缓冲区的状态



生产者和消费者用进程模拟。

-Producers and consumers (15 points) ◦　 a buffer of size 3, initially empty ◦　 2 producers　- random waiting time, add data to the buffer,- if the buffer is full, wait consumer removed data and then add- repeated six times ◦　 3 个 consumers- random waiting time, the data is read from the buffer- if the buffer is empty, waiting for the producers to add data after the read- repeated four times Descr iption: ◦　 display each times added time and read data buffer and the state with the producers and consumers of simulation processes.
