Consider the following concurrent tasks, in which each assignment statement executes atomically. Within a task, the statements o
ccur in order. Initially, the shared variables x and y are set to 0. Task 1 Task 2
x = 1 y = 1
a = y b = x
At the end of the concurrent tasks, the values ofa andb are examined. Which of the following must be true?
I. ( a == 0 ) ( b == 1 )
II. ( b == 0 ) ( a == 1 )
III. ( a == 1 ) ( b == 1 )
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) I, II, and III
Concurrent tasks is when there is more than one task to be performed but the order of the task is not determined. The tasks occur asynchronously which means multiple processors occur execute input instruction simultaneously. When x =1 and y = 1, the concurrent task will be performed and the a will be zero or either 1.
The above written is the segment of code is the structure of node of the linked list.The data of the node is type student.So the data of the node of the linked list will consist of the student details and the next is the pointer which holds the address of the next node.
