Since class 'Derived' is derived from 'Base' and consequently should be granted access to its protected members, the compiler complains about member 'X' being protected. class Base { protected: int X; }; class Derived : public Base { public: int Get(void) const; int Get(const Base & cl) const; }; int Derived::Get(void) const { return X; } int Derived::Get(const Base & cl) const { return cl.X; } >How-To-Repeat: Compile the program above. >Fix: Workaround: make base class member public >Release-Note: >Audit-Trail: >Unformatted:
