Derived classes inherit the member functions of the templated base class, which are not accessible by default, and are named for the templated base class.
The reason is that the customization of the template may cancel some functions, so that they cannot be accessed by default in order to detect errors at compile time.
Derived classes access templated base clas

Virtual functions:Purpose: To cause late bindingImplementation Method: Use the virtual keyword when declaring a function
Pure virtual functions:Objective: To provide abstract InterfacesImplementation Method: Virtual int Foo () = 0;Feature: If a class contains pure virtual functions, the vtable of the class is incomplete, so the object of the class cannot be generated. Such a class is called a pure abstract base class.

I finally figured out the problem, why didn't the Cellid of the WCDMA base station obtained by Google map mobile edition, MobileTrack, and FieldTest of network optimization be the CellTrack91 or the number in the base station table... This problem is very difficult to say. I have known it before, but I have never studied it in depth, because it does not affect my use. But I was bored lying in bed before I w
subways, basements, indoor, suburban, road, etc., is also a headache. Traditionally, due to the limitations of technology and equipment, operators and network design departments often use the common base station plus repeater to solve these problems. The disadvantage of this approach is that it will bring about increased interference, high drop rate, maintenance difficulties and so on. How to use a technical means to make the network appear "soft" ch
