, normal pointers do not have constructor and destructor, so we must write a class to add a layer. Packaging , The simplest is like this :" Class my_intptr{Public:Int * m_p; My_intptr (int * P) {m_p = P ;}~ My_intptr () {Delete m_p ;}}; ............ My_intptr Pi (New INT );* (PI. m_p) = 10; ............ "Here we can safely use my_intptr without worrying about memory leakage: Once the PI variable is destroyed, we know that the memory block pointed to by PI. P will be released. However, it w

For ordinary users, browsers need us to really operate a few places, but the favorites has always been a must not open the issue. Whether favorites can be freely imported and created directly affects the user's experience in using the browser, let's take a look at how smart 2345 Smart browsers are in favorites Management today. When it comes to favorites management, the first thing we think about is import

Smart pointers to c++11Original link: To c++11 smart pointers, forwarding please indicate the source. long-awaited begins. The last article "from the Auto_ptr" in detail summed up the c++98 standard in the auto_ptr, but with the arrival of C++11, Auto_ptr is no longer, is about to become history; good things are always welcome, as everyone is using "quasi" Standard library boost shared_ptr;c++ Standards

Switches are constantly evolving along the speed, multi-layer switching, and intelligent exchange directions. A new trend is that intelligent exchange at the edge access layer drives the development of intelligent exchange from the core of the network to the edge. In the past, the network architecture only adopted layer-3 routes of smart switches and layer-4 to layer-7 Smart switches at the core. On the edg

Clause 8: familiar with the rules for using smart pointersIn chapter 1, we came into contact with the general interface reference counting rules (Clause 2 ). Before starting this chapter, let's take a look at the rules that smart pointers should follow. The rules used by smart pointers are more complex than those used by interface pointers, but take into account

As a smart hardware and smart home enthusiasts, I understand that the current smart lamp mainstream technology has Bluetooth, ZigBee, WiFi and so on, so bought a representative of each technology products, and made some trial summary. Summary of the technical, if there is no understanding of technical terms, interested readers can search on the web to understand.

Reprinted from http://www.elecfans.com/analog/20111024225773.html Overview Smart locks refer to locks that are more intelligent than traditional mechanical locks in terms of user identification, security, and management. It is the execution part of the locks in the smart access control system. Currently, common smart locks in applications can be classified by use

Photoshop sharpening filters have the USM sharpening, further sharpening, sharpening, edge sharpening and intelligent sharpening five kinds. The "USM Sharpening" filter is to sharpen the image by enhancing the contrast of the edges of the image, and the greater the sharpening value the easier it is to produce black edges and white edges; And the "sharpen", "sharpen" and "Edge sharpening" filters are the software set default values to sharpen the image, the result is beyond control, the more sh

For a long time, my work was almost always a WEB application. When I was building a smart client application, I was very confused at first and didn't know how to build such an application. How do I handle data access? How does a smart client application communicate with a server? And I've invested a lot, I've got some tools that can significantly reduce development time and cost, and I really want to conti

Intel Smart Connect technology abbreviation Isct,intel for intelligent connections, this technology provides an "instant" networking feature that can "update" Application data over the Internet when the platform is in sleep (standby) mode. This means that the technology is to regularly wake up the computer from sleep, but do not open the screen, networking for a period of time so that the program has the opportunity to update, and then automatically r

Can Halow promote WiFi to become the first choice for smart home connection? In January 4, 2015, the Wi-Fi Alliance released a new low-power WiFi technology HaLow, which claims to be perfect for smart homes. Halow uses a 900 MHz frequency band. Compared with the previous 2.4G and 5GWiFi, Halow features lower power consumption, stronger wall-crossing capabilities, and longer coverage distance. This technolo

In April 23, 2014, Xiaomi, who entered the routing field with Internet thinking, released two routers in Beijing Zhongguancun Software Park, a high-end vro with a built-in 1 TB hard drive, A vro with no built-in hard disks. Of course, the h
