5. Producer and Consumer problems. (15') There are two processes running simultaneously in the system, and one is named Producer, the other one named Consumer. (1). Producer and Consumer share a bounded buffer: Producer produces one product and put it in the buffer, and Consumer just takes one product from the buffer. The default buffer size is 10. (2). Utilize your learned knowledge to solve the sharing problems in Producer and Consumer programs. Write the Producer, Consumer process and main function using C/C++/Java/Python language.
