I'm really not sure how to title the question briefly. Situation: In C++20. There is a Base as an interface, which specifies all the features ( ...
I wonder if there is any benefit of using CRTP over virtual function polymorphism if I never invoke the function from the base class (i.e., virtual di ...
Consider the following code: Do the header files of Type_A and Type_B have to be included or is it safe to forward declare those types? Note that t ...
I have the following piece of code: #include <iostream> class AnimalRepository { public: virtual ~AnimalRepository() = default; virtu ...

Suppose that you have an abstract template class IParser that has a virtual method called parse that should parse a string and return an object of tem ...
I have a base class A, which does some preliminary stuff. There are 2 subclasses B and C, whose behaviours are slightly different from each other. The ...
As far as I understand, objects of concrete types D with virtual member functions should be used through pointers to their (possibly abstract) base cl ...
I am using an LCD library from mbed, called TextLCD, and want to modify it so that it can act as the concrete class for an Interface LCD Class. In th ...
Consider: This is my code. Why can I call Base::foo() in the Derived class if I already redefined it in Derived class. Why doesn't the compiler del ...
I'm writing a hierarchy of classes of C++, let's say A, B inheriting A, C inheriting A, and D inheriting B. Now, all of these classes must have a met ...
I have the following Header/Source files: It is crucial, that the "fallback"-Version of func has the same name as a virtual function but differen ...
By using objects of the following structure(some bits simplified): In some cases a segfault is being thrown. In my understanding, this structure s ...

I'm writing a C++ state machine for Cortex-M4. I use ARM GCC 11.2.1 (none). I'm making a comparison between C and C++ output assembly. I have the fol ...
I have two questions here. Is it necessary to add the virtual keyword in the derived class? Is there any difference between returning a pointer ...
I have a lot of different child classes (15+) that all have the same function centerAt defined inside of them. Those child classes each inherits a dif ...
