Concept: The complex function of an entity is separated from the entity, and this complex function is diverse.For example, clothing factories (entities) have the function of making clothes, each garment has a different manufacturing process, thus

Pointers and const As with references, you can also point a pointer to a constant or a very good amount. Like a constant reference, a pointer to a constant (pointer to const) cannot be used to change the value of the object it refers to. To store
