Producer-Consumer Problem using C/C++ and Pthread API(Thread-safe)

Producer-consumer Problem using C/C++ and Pthread APIs (Thread-safe) Do programming project 3: Producer-Consumer Problem described in pp. 253-255 in Textbook 9-th ed. using Pthread APIs and C (or C++) language on Linux with the following additional requirements: As described in the text, your program should be run in the following way: % ./producer_consumer2 how_long_to_sleep_in_seconds num_of_producers number_of_consumers For example, %./producer_consumer2 180 10 20 Your program will As soon as the program starts, read all the words in [login to view URL] into an array Create 10 producer threads Create 20 consumer threads Each producer/consumer thread should run an infinite loop doing one of the followings: o Each producer thread sleeps for a random period of seconds (between 0 and RAND_MAX), upon awakening, will attempt to insert a word randomly selected from the list of words in [login to view URL] into the buffer. Whenever a randomly selected word is inserted into the buffer, the information should be printed on the screen (i.e., thread_id and the word) o Each consumer thread sleeps for a random period of seconds (between 0 and RAND_MAX), upon awakening, will attempt to remove a word from the buffer. Whenever a word is removed from the buffer, the information should be printed on the screen (i.e., thread_id and the word) Your program will run for 180 seconds. An outline of the producer and consumer threads is shown in Figure 5.26. Requirements:  The name of the executable file should “producer_consumer2”.  RAND_MAX should be 10 (i.e., 10 seconds)  Your program should be use all of the following Pthread APIs correctly! o mutex_lock, mutex_unlock, sem_wait, sem_post o You have to use BOTH MUTEX AND SEMAPHORE.  In your code, you can use sleep(seconds) API to make threads to sleep for seconds.  You need to provide a write-up in plain text format describing your source code (300 words or more).  Each producer/consumer thread should print out a message whenever some value is inserted into the buffer or removed from the buffer along with its own identifier. Use the following message formats: [consumer thread ID: 2] removed an item (word: apple) from the buffer [producer thread ID: 1] inserted an item (word: orange) to the buffer Recommended Testing scenarios:  Only producer threads are running 4 o ./producer_consumer2 180 10 0  All producer threads should be blocked eventually since there is no consumer thread.  Only consumer threads are running o ./producer_consumer2 180 0 10  All consumer threads are blocked at the beginning since there is no data to be read by the consumer threads  Multiple producer threads and multiple consumer threads %./producer_consumer2 180 10 20
