ISRO | ISRO CS 2014 | Question 36

Consider a standard Circular Queue ‘q’ implementation (which has the same condition for Queue Full and Queue Empty) whose size is 11 and the elements of the queue are q[0], q[1], q[2]…..,q[10].
The front and rear pointers are initialized to point at q[2] . In which position will the ninth element be added?
(A) q[0]
(B) q[1]
(C) q[9]
(D) q[10]


Answer: (A)

Explanation: Circular queue whose total size is 11, front and rear pointers are initialized to point at q[2]:
