The VTable is created at compile-time itself. But properly
initialized at runtime, including vptr.
Virtual Mechanism is possible only with completely
constructed objects. The constructor is called when the
object is not created completely, it is not allowed.

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
