We know that in C + +At the time of development, the destructor of the class used to do the base class is generally a virtual function. But why do you do that? Here's a small example: There are two classes:classclxbase{ Public: Clxbase () {};

Array definition: A set of variables of the same data type arranged in a certain order; the name of the set is called the array name ; Each variable has a number, which is called subscript ; Each variable that makes up the array is also called an
