How to access base class's member variable in c++?

Question

I'm trying to access base class's member variable.. How to do that?

===================== Following is ClassA (parent class) ===========================

class ClassA { public: int member_Var; // Parent member_var ClassA(); ~ClassA(); void ClassA::initProcess(); }; ClassA::ClassA(){} ClassA::~ClassA(){} void ClassA::initProcess() { member_Var = 20; }

================= Following is ClassB of ClassA's subclass ================

class ClassB : public ClassA { public: int member_Var; // Subclass member_var ClassB(); ~ClassB(); void ClassB::initProcess(); }; ClassB::ClassB(){} ClassB::~ClassB(){} void ClassB::initProcess() { ClassA->member_Var = 10; // Is this correct? or How to access base instances's member variable? member_var = 100; }

You need to specify ClassA::member_Var to explicitly refer to the one in base class.

void ClassB::initProcess() { ClassA::member_Var = 10; member_var = 100; }
