我们的课设报告，用多线程解决经典的生产者与消费者问题，用锁操作原语实现互斥。-Our class set up the report, using multiple threads to solve the classic problem of producers and consumers, with the locking primitives, to achieve mutually exclusive.

多线程实现生产者消费者模型，分为四个函数，一个为生产者函数，一个消费者函数，一个退出函数，一个 主函数。-Multi-threaded implementation of the producer-consumer model, divided into four functions, a function as a producer and a consumer function, an exit function, a primary function.
