4.	(a).	A student has produced the code below for Consumer process only.
			semaphore full = 0; semaphore empty = n; semaphore mutex = 1; void Consumer() { While (true) { P(full); P(mutex); Read_from_buffer(); V(mutex); V(empty); Consume(); } }//end consumer()
		(i).	Examine the uses of semaphore variables mutex, full and empty.
		(ii).	What will happen if the student runs the above code? Explain your answer.

0; semaphore full semaphore empty semaphore mutex = n; 1; = void Consumer () { While (true) { P (full); P (mutex); Read from buffer(); V (mutex); V (empty); Consume(); } }//end consumer ()
