In the whilestatement of the method getNodeBefore, how important is theorder of the two boolean expressions that the operator &&joins? Explain.
What will be an ideal response?
The order of the boolean expressions is important. If the given entry—anEntry—is larger than any of the current entries in the sorted list, curPtr will become nullptrafter it is compared to the list’s last entry. The while statement will then evaluate the expression(curPtr!=nullptr)&&(anEntry>curPtr->getItem()). Because curPtr is nullptr, curPtr!= nullptr will be false and curPtr->getItem() will not execute due to short-circuit evaluation. If the boolean expression had been (anEntry>curPtr->getItem())&&(curPtr!=nullptr),curPtr->getItem() would execute and since curPtr is nullptr, an exception would occur.
