Protected. Protected access modifier is similar to that of private access modifiers, the difference is that the class member declared as Protected are inaccessible outside the class but they can be accessed by any subclass (derived class) of that class. Example: #include <bits/stdc++.h>. using namespace std;In C++, to override a base class method in a derived class, we first have to declare that function as a virtual function in the base class. After that, we can redefine …A class that declares or inherits a virtual function is called a polymorphic class. Note that despite of the virtuality of one of its members, Polygon was a regular class, of which even an object was instantiated ... Virtual members and abstract classes grant C++ polymorphic characteristics, most useful for object-oriented projects. Of course ...Using namespace. Namespaces are used at the very least to help avoid name collision. In Java, this is enforced through the "org.domain" idiom (because it is supposed one won't use anything else than his/her own domain name). In C++, you could give a namespace to all the code in your module.Example 2: Add Members of Two Different Classes. // Add members of two different classes using friend functions #include <iostream> using namespace std; // forward declaration class ClassB; class ClassA { public: // constructor to initialize numA to 12. ClassA() : numA(12) {}Dec 12, 2009 · 6. Classes in C are most often simulated by structs combined with function pointers. Non-virtual functions can be passed alongside a pointer to the struct, like so: int obj_compare_funct(Obj *a, Obj *b); int result = compare_two_objects(obj1, obj2, obj_compare_func); But the real fun starts when you embed the pointers in the struct; this means ...
