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?

For classes with common behavior, you can save effort by placing the common behavior in a __________

C++ compiler does not allow to dynamically allocate memory for objects

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

The statement objA=objB; will cause a compiler error if the objects are of different classes

Consider the code below, class Fred { public: Fred(); ... }; int main() { Fred a[10]; Fred* p = new Fred[10]; ... } Select the best option,
