CS 373 Home Work project 11 Create a queue class by priviate inherting the unorderedArrayListType class. A queue class is a First-In-First-Out data structure. To understand a queue, think of a checkout line at a grocery store: the person at the front is served first (removed), and people are added to the line from the back end. class queue : private unorderedArrayListType { public: bool isEmpty() const; // test whether queue is empty // Post: returns true if queue is...

PROBLEM- void CBQueue::printF2B( ) If the queue is empty, the method should print “Queue is empty”, otherwise, this method should print the items in the queue starting at the front of the queue and proceeding to the rear of the queue. The items should be printed one per line. Now that this method is written, you can do a more thorough job of testing enqueue( ). You will want to call printF2B( ) and printB2F( ) after implementing each method...
