Intelligent switches have become very important devices in networking. Here we analyze the smart features of ProSafe smart switches. The increasing network scale or complexity makes management more difficult, greatly reducing network performance and user satisfaction. With basic management features, you can increase network performance and reliability, accelerate fault resolution, enhance security, and cont
Smart Pointers-what, why, which?
What are they?
Smart pointers are objects that look and feel like pointers, but are smarter. What does this mean?
To look and feel like pointers, smart pointers need to have the same interface that pointers do: they need to support pointer operations like dereferencing (operator *) and indirection (operator-> ). an object that lo
Smart contracts are a key underpinning of blockchain technology, but they are still misunderstood in many ways.
The HTML markup language allows information to be published and connected through a Web page, but in the complete deployment of the blockchain it is no less revolutionary than the invention of the HTML markup Language. Smart contracts can use cutting-edge blockchain to design our world, and may re
Reference counting smart pointerI. Introduction
Since the C ++ language does not have an automatic memory reclaim mechanism, the programmer must manually delete the new memory each time. When the programmer forgets to delete, the process is too complex and eventually leads to the absence of delete, exceptions lead to premature exit of the program, and the absence of delete execution is not uncommon. Using Smart
Chapter 2 Smart Clients
The transformation of software from the host system to the C/S structure not only brings about reasonable allocation of system resources, but also brings about a new client experience, in particular, the extensive use of graphic interface systems (mainly Windows operating systems) provides a high-quality, Responsive user experience, and has good support for developers and platforms. However, it is very difficult to deploy and m
Why does a smart pointer still need release? Isn't it necessary to manage the reference count? Why?ProgramMember to release?
The reason is that the smart pointer object releases the interface pointed to when the object is destroyed, but if you destroy the com library before the function exits, you need to release it in advance.
For example:
: Coinitialize (null); // If Initialization is performed here
PS students know that there is such a thing, called smart object.
What exactly does it have in the egg?
A, smart object differs from a normal layer, which retains the source content of the image and all its original attributes.
In other words, no matter how you scale the selection of smart objects, it will not lose the original information.

The most prominent feature of a smart switch is its ability to expand management capabilities to comprehensively improve network performance and responsiveness, allowing users to enjoy a free network environment. The increasing network scale or complexity makes management more difficult, greatly reducing network performance and user satisfaction. With basic management features, you can increase network performance and reliability, accelerate fault res

C + + smart pointer is mainly on the basis of ordinary pointers encapsulated a layer, so that users of the use of pointers more convenient and rest assured that in the process of use without worrying about the pointer because of the problem caused by the exception.
