When you are designing a generic class to contain or otherwise manage objects of other types, when the format and behavior of those other types are unimportant to their containment or management, and particularly when those other types are unknown (thus, the genericity) to the designer of the container or manager class.

Prior to templates, you had to use inheritance; your design might include a generic List container class and an application-specific Employee class. To put employees in a list, a ListedEmployee class is multiply derived (contrived) from the Employee and List classes. These solutions were unwieldy and error-prone. Templates solved that problem.

class A { public: void f(); protected: A() {} A(const A&){} }; Examine the class declaration shown above. Why are the default and copy constructors declared as protected? 1. To ensure that A cannot be created via new by a more derived class 2. To ensure that A cannot be copied 3. To ensure that A cannot be used as a base class except when public inheritance has been used 4. To ensure that A cannot be created/copied outside the inheritance chain 5. To ensure that A cannot be instantiated as a static variable
