I have a base class and a derived one and 开发者_运维问答I want to change base functions while keeping them static as they should be passed to other functions as static.
I have开发者_高级运维 4 WinForm app. Form1 inherits from baseForm, Formv2 inherits from Formv1, v3 from v2, v4 from v3. There are about 2 thousand controls spread across many tabs that contain tabs.
Why static_cast cannot downcast from a virtual base ? struct A {}; struct B : public virtual A {}; struct C : public virtual A {};
I understand the need for virtual inheritance when using multiple inheritance -- it solves the Dreaded Diamond Problem.
Does using virtual inheritance in C++ have a runtime pe开发者_StackOverflow社区nalty in compiled code, when we call a regular function member from its base class? Sample code:
Based on http://en.wikipedia.org/wiki/Virtual_inheritance class Animal { ... }; // Two classes virtually inheriting Animal:
I am considering using virtual inheritance in a real-time application. Does using virtual inheritance have a performance impact similar to that of calling a virtual function? The objects in question w
I am developing a test-framework. There are a number of test-suites, each is a class with a set of member functions for each individual test.
Suppose a class Y publicly inherits a class X. Is it possible for a class Z to privately inherit Y while publicly inheriting X?
While I learn how to implement a final class in C++, I find such a statement: \"the most derived class\'s ctor needs to directly call the virtual base class\'s ctor.\"
