}
Remainder Section
Here, w1 and w2 have shared variables, which are initialized to
false. Which one of the following statements is TRUE about the
above construct?
Lütfen birini seçin:
O a. It satisfies the mutual exclusion
O b. None of the options
O c. The processes should enter the critical section in strict alternation
O d. It does not satisfy the mutual exclusion
O e. It does not satisfy the bounded waiting

Two processes, P1 and P2, need to access a critical section of code. Consider the following
synchronization construct used by the processes.
Process P1:
while(true)
{
w1 = true;
while(w2 == true);
Critical section
w1 = false;
Remainder Section
Process P2 :
while(true)
{
w2 = true;
while(w1
== true);
Critical section
w2 = false;
}

Which of the following statements are true? options: Every class has a copy constructor with the signature ClassName(const ClassName&). The copy constructor can be used to create an object initialized with another object's data. By default, the copy constructor simply copies each data field in one object to its counterpart in the other object. By default, the copy constructor performs a shallow copy.
Consider the following code snippet: waitpid(-1, &status, 0); Which of the following correctly describes the purpose of this code snippet? it is equivalent to wait(&status); it causes the parent process to wait for the child process that terminates first and fetch that child's termination status it causes the parent process to wait for the child process whose pid is -1 and fetch that child's termination status The first two choices are both correct None of the above choices are correct Which of the following statements about wait(2) and waitpid(2) are true? The waitpid(2) function can block the caller until a child process terminates, whereas wait(2) has an option that prevents it from blocking. The wait(2) function doesn't wait for the child that terminates first; it has a number of options that control which process it waits for. If a child has already terminated and is a zombie, wait(2) returns immediately with that child's status. Otherwise, it blocks the caller until a child…
