multiple inheritance with a common base hybrid inheritanceinheritance is an important and powerful feature of oop only the imagination of the person
problems with multiple inheritancethe following example presents a problem with multiple inheritanceclass aclass public void
multiple inheritancemultiple inheritance as the name suggests is deriving a class from more than one class the derived class inherits all the
multilevel inheritancein multilevel inheritance there is a parent class from whom we derive another class now from this derived class we can derive
nested classesmany a times it becomes essential to have a class contain properties of two other classes one way is to explain a class within another
object conversionsjust like initialization conversions are also done automatically when an object of a derived class is assigned to an object of the
object initializationan object of a derived class can be initialized to an object of a base class if both the classes have similar data members then
constructor and destructor function with derived classesif there are constructors included in the base class and the derived class the compiler
hiding overloaded functionswe cannot overload a base class function by redefining it in a derived class with a dissimilar argument list consider
access privileges1 if the designer of the base class needs no one not even a derived class to access a member then that member should be made
derivations1 regardless of the type of derivation private members are inherited by the derived class but cannot be accessed by the new member
protected derivationin addition to doing private and public derivations you may also do a protected derivation in this situation the private
public derivationpublic derivations are much more common than private derivations in this situation the private members inherited from the base class
private derivationif no specific derivation is listed then a private derivation is supposed if a new class is derived privately from its parent class
how to define a derived class a singly inherited derived class id defined by writing the keyword class the name of the derived class a single colon
what is inheritanceclass the vehicle which is used to execute object-oriented concepts in c has given a new dimension to this idea of reusability
reusability reusability means reusing code written earlier may be from some earlier project or from the library reusing old code not only saves
reference odditiesa reference variable can demote to any integer variable be it in an array or a member variable from structure or class reference
returning references from functionsjust as in passing the parameters by reference returning a reference also doesnt return back a copy of the
call by referencepassing variablesparameters to a function in c can be done in two ways - pass by value also called as call by value and pass by
precautions with function overloadingfunction overloading is a boon to designers since dissimilar names for same functions need not be thought of
function overloadingfunction overloading is a form of polymorphism function overloading facilitates explaining one function having many forms in
