Which one of the following features of OOP is used to derive a class from another?

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?

Which of the following are an advantage of OOP?

Static variable can be initialized more than once

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

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

Which of the following is not an example of multiple inheritances?----------

The concept of derived classes is involved in,
