If you use a circular chain that has only a tail pointer, as Figure 14-6 illustrates, how do you access the data in the first node?

What will be an ideal response?


First, you get a pointer to the first node by executing either of the following statements:
std::shared_ptr>frontPtr = backPtr->getNext();
or
auto frontPtr = backPtr->getNext();

Then the data in the first node is frontPtr->getItem().
