Class inheritance defines an object's implementation in terms of another object's implementation. Type inheritance describes when an object can be used in place of another. #include <iostream> #include <vector> using namespace std; class AlarmListener { public: virtual void alarm() = 0; }; ...

A Constructor in C++ is a special member function having the same name as that of its class, which is used to initialize some valid values to an object’s data members. It is executed automatically whenever an object of a class is created. The only restriction that applies to the construct...

These prototypes are not for normal use - they are akin to base classes in a prototypal inheritance system like JavaScript's. If you duplicate a prototype question the question type will become unusable, as CodeRunner doesn't know which version of the prototype to use. Upgrading from earlier ...
classis additionally allowed to be cast to pointer or reference to unambiguous base class (and vice versa) even if the base class isinaccessible(that is, this cast ignores the private inheritance specifier). Same applies to castingpointer to memberto pointer to member of unambiguous non-virtual ...
