Expression:
(x >= 0 && y<0) //check condition using AND operator
Explanation:
In the given question it is defined that x and y are an integer variable that holds some value, in which it defines a condition that checks the value of variable x is positive, and the value of y is negative.
- To check positive value a condition is used, that checks x greater than equal to 0, and to check negative value, it uses condition, that is y is less than 0.
- In the above condition, the AND operator is used, which executes when both conditions are true.
Answer: C) spin-lock with test and set
Explanation:
In spinlock, when a thread locks a spinlock then it continuously retrying locking until it succeeds. Spinlock is the lock that cause thread and continuously check that whether the lock are available or not for synchronization.
So that is why spinlock is best synchronization solution as it is not allowing any another thread.
On the other hand, in mutex thread try to lock a mutex and then, it automatically go to sleep mode before locking and immediate allow another thread to run.
