This article is not ready to introduce all of the Oracle functions, in the current situation, I do not have this time, need to learn too much, to spend most of the time on learning to use the technical aspects:), so if you are ready to learn all the Oracle functions of friends, or to focus on: Oracle SQL Reference official documents are more reliable. This article will cover a number of

Virtual function (impure virtual)The virtual function of C + + has the function of " runtime polymorphism ", which provides the implementation of virtual function in the parent class, and provides the default function implementation for subclasses .　　Subclasses can override the virtual functions of the parent class to implement the specialization of subclasses.The following is a virtual fun

In the face of C + + template, need to pay attention to, because the template of the complexity of a lot of circumstances, so the best way to learn the template I personally think that is used to learn, do not use to see all kinds of odd door strange skills, because you even see, very difficult to understand the template to achieve internal, including meta-programming AH what, But I believe very little in the work, and soon you will forget it, so, for the template, we can take the idea of where
