Inheritance offers the following advantages --

Developement model closer to real life object model with
hierarchical relationships
Reusability -- facility to use public methods of base class
without rewriting the same
Extensibility -- extending the base class logic as per
business logic of the derived class
Data hiding -- base class can decide to keep some data
private so that it cannot be altered by the derived class

class CTest { public: void someMethod() { int nCount = 0; cout << "This is some method --> " << nCount; } }; int main() { CTest *pctest; pctest->someMethod(); return 0; } It will executes the someMethod() and displays the value too. how is it possible with our creating memory for the class . i think iam not creating object for the class. Thanks in Advance... Prakash
