Page 351: Q 31 & 32: (Multiple Choice) The statement : queue.items[1]= queue.items[2];
The statement queue.items [1] = queue.items [2]; (setting one element equal to the next element) in a client program of the queue class a. would cause a syntax error at compile time. b. would cause a run-time error. c. would not be considered an error by the computer, but would violate the encapsulation of the queue data type. d. would be a perfectly legal and appropriate way to accomplish the intended task. The statements queue.Enqueue (item1 + 1); queue.Dequeue (item1 + 1); in the client program a. would cause a syntax error at compile time. b. would cause a run-time error. c. would be legal, but would violate the encapsulation of the queue. d. would be perfectly legal and appropriate. Given the following specification of a Front operation:Explanation / Answer
1) Option d is correct Since Only the value located in the Queue at position 2 will be assigned to position 1.
2) This will cause a Syntax error at Compile time since we cannot mention the position when we are using the method
queue.Dequeue(item1+1)
The last item will be removed hence we will simply Use
queue.Dequeue()
