First introduce a principle LSP (Liskov Substitution Principle), if Class D inherits Class B in public, then all B objects can be used anywhere, D objects are just as useful.For overloading and rewriting, I'm sure we all know something about it.

ATo achieve consistency operator new must return the correct value, must call the New_handling function when it is out of memory, must be prepared to deal with 0 of memory, and avoid accidentally masking the normal form of new.void* operator new

Base The base keyword is used to access the members of the base class from a derived class: Invokes a method on the base class that has been overridden by another method. Specifies the base class constructor that should be called when creating

The previous simple discussion of C + + object model, always feel not deep enough, is near idle to further mining C + + object memory layout. Main discussion: Single inheritance, multiple inheritance, virtual function of diamond inheritance

In C + +, derived virtual functions cannot be called from the constructor of a class because the virtual table is not yet fully established. But it seems to be possible in C #, isn't it? Why is there such a difference? Indeed, there is a difference

A lot. NET class provides two different ways to control the events of some systems. That is, either add an event handle, or override the base class's virtual function. Why do you offer two ways to do the same thing? In fact, it's very simple,
