At a particular time of computation the value of a counting semaphore is 7. Then 20 P operations and 15 V operations were completed on this semaphore. The resulting value of the semaphore is:
Correct Answer: B
Question 4 Explanation:
Let the semaphore be S.
Initial value of S is 7.
So after 20P operations and 15V operations the value of semaphore S will be,
S = 7 – 20 + 15 = 2
Initial value of S is 7.
So after 20P operations and 15V operations the value of semaphore S will be,
S = 7 – 20 + 15 = 2
