A virtual function is a memberfunctionin the baseclassthat we expect to redefine in derived classes. For example, classBase{public:voidprint(){// code} };classDerived:publicBase {public:voidprint(){// code} };
As we have seen in the above examples, method overriding is achieved by using both abstract and virtual keywords. Some key points to be remembered for implementing method overriding are:The overridden method should always be declared as abstract, virtual or override in the base class. The non-...
Access Specifiers in Method Overriding The same method declared in the superclass and its subclasses can have different access specifiers. However, there is a restriction. We can only use those access specifiers in subclasses that provide larger access than the access specifier of the superclass. F...

In a class hierarchy, A subclass can contain a method with the same signature and return type as in its superclass, then the method in the subclass is said to override the method in the superclass. However in certain situations, the subclass need to modify the implementation (code) of a...
