Variables defined inside a member function of a class have Select one: a. File scope b. Class or block scope, depending on whether the binary scope resolution operator (::) is used c. class scope d. Block scope

When using pointers or references to a base class, how should software invoke the same virtual function in different forms and structures?

C++ coding project just need some help getting the code thank you!

when an application uses pointers or references from the base class to call a virtual function, allowing several implementations of the same functionality to use the same code.

When a class contains a data member that is a pointer to dynamically-allocated storage, which of the following member functions should be implemented? All three of the member functions listed below should be implemented. The copy assignment operator. The copy constructor. The destructor.

// NOTE: Two separate versions of the sequence (one for a sequence of real numbers and another for a sequence of characters are specified, in two separate namespaces in this header file. For both versions, the same documentation applies.// TYPEDEFS and MEMBER functions for the sequence class:// typedef ____ value_type// sequence::value_type is the data type of the items in the sequence.// It may be any of the C++ built-in types (int, char, etc.), or a// class with a default constructor, an assignment operator, and a// copy constructor.// typedef ____ size_type// sequence::size_type is the data type of any variable that keeps// track of how many items are in a sequence.// static const size_type CAPACITY = _____// sequence::CAPACITY is the maximum number of items that a// sequence can hold.//// CONSTRUCTOR for the sequence class:// sequence()// Pre: (none)// Post: The sequence has been initialized as an empty sequence.//// MODIFICATION...
