Virtual functions ensure that the correct function is called for an object, regardless of the expression used to make the function call. Suppose a base class contains a function declared as virtual and a derived class defines the same function.

But Verizon is taking things to a new, terrible level, according to MacRumors. Beginning April 4th, Verizon will charge a $20 upgrade fee even for customers buying a device outright / paying full price. So if you're handing Verizon $800 for an iPhone 6S or a Galaxy S7 Edge, well, that makes no difference. They'll still empty your pockets for another $20.
