Virtual Functions

0. Given the following statements, select which function(s) get used. Both Base and Derived have virtual functions, virtual destructors, copy constructors and operator =. Also, unless otherwise specified default values are used. A. Base* pderived = new Derived; a. Base constructor b. Derived constructor c. Base copy constructor d. Base operator = B. Base base = *pderived; // from part A a. Base default constructor b. Base copy constructor c. Derived default constructor d. Derived copy constructor C. base = *pderived; // from part A & B a. Base copy constructor b. Derived copy constructor c. Base operator = d. Derived operator = D. [login to view URL](); // from part B, function is non-virtual a. Base function b. Derived function E. pderived->function(); // from part A, function is non-virtual a. Base function b. Derived function F. [login to view URL](); // from part B, function is virtual a. Base vfunction b. Derived vfunction G. pderived->vfunction(); // from part A, function is virtual a. Base vfunction b. Derived vfunction H. delete pderived; // from part A a. Base destructor b. Derived destructor 1. Using the derived passenger classes from lab4, write a polymorphic function that can take any of the three types of passengers, and access any of the virtual functions. 2. Show how to have a base class copy constructor get called from a derived class copy constructor: 3. Convert this class to be a generic: class triple { int first; double second; string third; public: triple(int f, double s, string t) : first(f), second(s), third(t): { } int getfirst() { return first; } double getsecond() { return second; } string getthird() { return third; } void setfirst(int f) { first = f; } void setsecond(double s) { second = s; } void setthird(string t) { third = t; } }; 4. Describe, in a short paragraph, the difference between inheritance by value and inheritance by reference.
