First, the explicit keyword in C ++ can only be used to modify the class constructor with only one parameter. Its function is to indicate that the constructor is displayed, rather than implicit, another keyword corresponding to it is implicit,It

C ++ copy constructor (deep copy, light copy) For common objects, copying between them is very simple, for example:Int A = 88;Int B =;Different from common objects, class objects have complicated internal structures and various member variables.

1. Override refers to the function of a derived class that overwrites the base class function. The features are as follows:(1) different scopes (located in the derived class and the base class respectively );(2) The function name is the same;(3) The
