Jquery implements smart forms and jquery smart forms
Currently, many website registration modules can check whether the format is correct in real time. This greatly enhances the user experience and is very beneficial to development.
The following code uses jquery to instantly check the format of a form field (including the Field Length and email format). At the same time, it checks the event again when subm
Use JavaScript + Ajax to implement Baidu Smart Search box and ajax Smart Search
First, view the result after implementation. after entering a value, a drop-down list containing a will appear. When we click a value, the value will appear in the search box. The main requirement for implementation is ajax + js.

The File command can identify the files of a given file type, such as:filelf.gz, whose output is:Lf.gz:gzip compressed data, deflated, original filename,Last Modified:mon 23:09:18 2001, Os:unixWe use this to write a script called Smartzip , which automatically extracts compressed Files of bzip2, gzip, and zip types:#!/bin/bashFtype= "$ (file" $ ")"Case ' $ftype ' in"$1:zip Archive" *)Unzip "$";;"$1:gzip Compressed" *)Gunzip "$";;"$1:bzip2 Compressed" *)Bunzip2 "$";;*) echo "File" can not is unco
Another solution for BS/CS is the smart client in. net.
This is also a method highly praised by Microsoft. It combines the advantages of the BS and CS modes,
Still use winform mode to develop the client ......

In this paper, the concept and usage of the intelligent pointer in C + + are explained in detail, which helps readers to deepen their understanding of the intelligent pointer. Details are as follows:
First, Introduction
Because the C + + language does not have an automatic memory recovery mechanism, the programmer will manually delete each new memory. The programmer forgets to delete, the process is too complex, resulting in no delete, and the exception causes the program to quit prematurely,

Understanding smart contracts is critical to understanding blockchain technology. Let's take a look at what is a smart contract first.
The smart contract is the 1990s era of the concept proposed by Nick Saab, almost the same age
1. The role of intelligent pointers
The use of heap memory in C + + programming is a very frequent operation, and the application and release of heap memory are managed by the programmer. Programmers manage heap memory themselves can improve the efficiency of the program, but the overall management of heap memory is troublesome, C++11 introduced the concept of intelligent pointers to facilitate the management of heap memory. Use of common pointers, easy to cause heap memory leaks (forget to rel
ObjectiveThe recent period of time to look at the code, the use of C + + smart pointers, found that they can not understand the code in the expression of what meaning, so dedicated to take a time to make up their own this lack of knowledge.Reference book "in-depth application c++11: Code Optimization and Engineering Application"Smart pointersThe C++11 provides 3 smart
C + + Smart Pointer detailed
First, Introduction
Because the C + + language does not have an automatic memory recovery mechanism, the programmer will manually delete each new memory. The programmer forgets to delete, the process is too complex, resulting in no delete, and the exception causes the program to quit prematurely, and it is not uncommon to not execute the delete.
Using smart pointers can effecti
First, the concept of smart pointersThe smart pointer is a class, not a pointer , and the smart pointer automatically frees the system resources that are used by the contained pointer when it is no longer in use, rather than manually releasing it.Principle: The smart pointer encapsulates the AddRef () function and the

To address the problem of C + + memory leaks, C++11 introduced smart pointers (smart Pointer).The principle of smart pointers is to accept a well-applied memory address, construct a smart pointer object stored on the stack, there is an important principle in C + +, at the end of the function (whether it is normal retur
a class to add a layer of packaging, the simplest is like this: "Class My_intptr{Publicint* 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 leaks: Once the PI variable is destroyed, we know that the memory block pointed to by PI.P is bound to be freed. But it would be too much trouble to access its members every time you use MY_INTPTR. To do this, you can
What is a smart client? To fully understand how a Smart Client combines the advantages of a fat client with a thin client, it is useful to analyze the history and basic principles behind the fat/thin client application model, and review the advantages and disadvantages associated with them.Fat client application In the middle of 1990s, the number of fat client applications developed for Microsoft (r) Window
normal pointer has no constructors and destructors, so we have to write a class to add a layer of packaging, the simplest of which is like this: "
Class My_intptr{Publicint* 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 leaks: Once PI is destroyed, we know that the block of memory that PI.P points to is bound to be released." But it would be too much
