1. Local Variables:A local variable is a variable in a method of a class;2. Instance variables:Instance variables are also variables that are independent of the method in the class, but do not have static adornments, also called object variables3. Class

create another class, change the value to public, and then use it to "hide" the value member in the original object?The reason is that the C ++ language only ensures the same access section in the class (that is, the part between an access permission modifier public/private/protected and another modifier) non-static member v
