Starting from the introduction of basic concepts, this paper discusses the data structure and functions used in the operation of date and time in C/A + +, and expounds the timing, time acquisition, time calculation and display format. This article

It is really convenient to connect to the database by BDE aliases, but we cannot create aliases for those databases that are not identified. And most of the time, when we give the program to someone else to actually put it into use, the path to the

The persistence of an object is a core function of a type. This is one of the basic elements that no one will notice until you ignore its support. If your type does not properly support serialization, you will add a lot of work to developers who

with wings to fly, lack of flexible code is like a bird with a broken wing. Can not fly, there is less of the spirit of the smart. We need to bring the code to the warm sun, let turn cold wings to fly again. With examples, by applying OOP, design

Example IntroducedAn enumeration is a specified constant whose underlying type can be any integral type other than Char.If the underlying type is not explicitly declared, the Int32 is used.Programming languages often provide syntax to declare

The smart pointer contains two kinds of "shared_ptr" and "unique_ptr", because the two kinds of pointers are implemented differently, so the way to pass the deletion is different; "shared_ptr" of the transfer of the deletion (deleter) way is

The beta version of the Visual C + + 2008 Feature Pack is already available for download. This feature Pack expands the VC + + class library that is published with Visual Studio 20,081, with the most significant number of extensions to the MFC

In the current development process, we often use extension methods to reduce the amount of code in a single file and reduce the chance of exclusive locking of files in collaborative development. Extension methods enable you to add a method to an

The smart pointer behaves like a pointer, but does not provide added functionality. For example, Item 13 explains how to use the standard auto_ptr and tr1::shared_ptr pointers to automatically delete resources on the heap at the correct time.
