Your chief Software designer has shown you a sketch of the new Computer parts system she is about to create. At the top of the hierarchy is a Class called Computer and under this are two child classes. One is called LinuxPC and one is called WindowsPC. The main difference between the two is that one runs the Linux operating System and the other runs the Windows System (of course another difference is that one needs constant re-booting and the other runs reliably). Under the WindowsPC are two Sub classes one called Server and one Called Workstation. How might you appraise your designers work?

Static variables act like a global variable in the context or scope of the class

A non-virtual member function is defined in a base class and overridden in a derived class; if that function is called through a base-class pointer to a derived class object, the derived-class version is used

Which of the following is the best approach if it is required to have more than one functions having exactly same functionality and implemented on different data types?

The concept of derived classes is involved in, 

If you define a vector v with the default constructor, and define another vector w with a one-argument constructor to a size of 11, and insert 3 elements into each of these vectors with push_back(), then the size() member function will return ______ for v and _____ for w

 _______ remain in memory even when all objects of a class have been destroyed

Which part of an object exhibits its state?

What problem(s) may occur when we copy objects without using deep copy constructor?

this pointers are not accessible for static member functions

Given the following class class Base{ int Age=33; } How you can improve above class with respect to accessing the field Age?
