Class B is a protected base class of class D. Protected members of the base class B are O not accessible by the member functions of class D O inherited as protected members of the class D None of these O inherited as public members of the class D

If a base class has a non-virtual member function named print, and a pointer variable of that class is pointing to an object of a derived class, then the code ptr->print(); calls

Assuming class B has a pure virtual member function, choose the best statement below. Assuming class B has a pure virtual member function, choose the best statement below. class B is an abstract class we cannot instantiate objects of class B both of these statements are true

write the definition of a class statistics containing: three data members x, y, and z of type integer. a member function called setValues that accepts three parameters and assigns them to x, y, and z the function returns no value. a member function called getSum that accepts no parameters and returns the sum of the member variables x, y, and z. a member function called getAvg that accepts no parameters and returns the average of the member variables x, y, and z (the average should be returnsed as a double value. to do this you can use a convert function or just divide by 3.0) a member function called getMin that accepts no parameters and returns the smallest member variable. a member function called getMax that accepts no parameters and returns the largest member variable.

A member variable declared in the private section of a base class can be directly accessed within a member function of a derived class that inherits from this base class. True False

Representing a point in the plane, a class named PlanePoint has • Two data members i.e. X and Y (correspond to x and y coordinates) of integer type, • Two accessor functions named as getX() and getY() to get values of data members X and Y• A function named planeDistance() that calculates and returns the distance between two points in a planeDerive a class named SpacePoint to imagine a point in a three-dimensional space and has following additional features:• A data member Z of type integer to represent the z-coordinate of a point in space• A no-argument constructor that constructs a point with coordinates (0,0,0)• A constructor with three arguments that constructs a point with three specified coordinate values• An accessor function, which returns the value of data field Z• A function named spaceDistance to return the distance between two points in the spaceImplement both the classes and in the main() create two points with different dimensions and invoke appropriate function to display…

If a class inheriting an abstract class does not define all of its functions then it is known as? a) Abstract b) A simple class c) Static class d) None of the mentioned
