说明：  • 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。
(• a buffer of size 3, initially empty • 2 x producers- random wait time, add data to the buffer,- if the buffer is full, waiting for consumers to get data and then add- repeated six times • 3 Consumer- random wait some time to read data from the buffer- if the buffer is empty, add data and then wait for the producer to read- repeated four times Description: • Display and read the data every time you add a time and buffer status • producers and consumers to use process simulation.)
