Why do we actually need Private or Protected inheritance in C++? http://stackoverflow.com/questions/374399/why-do-we-actually-need-private-or-protected-inheritance-in-c a base class class Base class Derived1 private Base class Derived2 protected Base Is it really useful c inheritance private protected..
What are access specifiers? Should I inherit with private, protected or public? http://stackoverflow.com/questions/5447498/what-are-access-specifiers-should-i-inherit-with-private-protected-or-public Allowed b 20 Allowed c 30 Not Allowed Compiler Error class Derived2 public Derived void doSomethingMore a 10 Not Allowed Compiler..

In a templated derived class, why do I need to qualify base class member names with “this->” inside a member function? http://stackoverflow.com/questions/7908248/in-a-templated-derived-class-why-do-i-need-to-qualify-base-class-member-names-w class Base0 public int nd template typename T class Derived2 public Base0 non dependant base public Base T dependant base.. is instantiated for example f in f this . At the point of Derived2 f definition there is no variable function or type name f known.. int . The consequence of this is that the class template Derived2 has a complete base class Base0 but an incomplete forward declared..
