Variable arrays are already supported in C99, but not supported in VC, but flexible arrays (special variable-length arrays) are supported. What is a flexible array, how to use it. Please look at the code below. #include

With the popularization of the network and the rapid increase of the number of users, the market demand for tiered switches has expanded rapidly. However, many of the tiered switches in the scalability, flexibility, manageability and so on, there are a lot of unsatisfactory places, especially the expansion of flexibility is poor, it is difficult to meet users fast, smooth and flexible to achieve network expansion needs. In view of this situation, as o

PrefaceMyBatis, as we all know, the semi-automatic ORM framework, originally called Ibatis, and later seemed to be the 10 Apache software fund hosting it to Goole Code, renamed the MyBatis, the function is more powerful than before. It's a relatively fully automatic, durable framework hibernate, more flexible and lightweight, which I still have a deep understanding of.One of the powerful features of MyBatis is the dynamic SQL capability, can save us a

The dnw source code in the previous article uses such a struct: Struct download_buffer {uint32_t load_addr;/* load address */uint32_t size;/* data size * // size = address (4 bits) + size (4 bits) + Data + verification (2 bits) uint8_t data [0]; // an array of 0 lengths pointing to data/* uint16_t checksum; * // the two following the array are check bits }; Data [0] is a zero-length Array Used for flexible expansion of struct. Allocate memory space:

too large or too small to display. When the screen is too small, the content block is fixed to a specified width, a horizontal scroll bar appears at the bottom of the screen, and when the screen is too large, the content is fixed to the maximum width, so as not to stretch too open, affecting the readability of the text.Unfortunately, most versions of Internet Explorer do not support these two property values. This problem can be solved by IE's unique expression.6.

"Preface" often see two arrays in C language, summarize.First, a flexible arrayReference: https://www.cnblogs.com/veis/p/7073076.html#include 　　As we can see, the size of the _softarray structure is 4, and it is clear that the next int variable size in the 32-bit operating system is exactly 4, which means that the array in the struct does not occupy memory. Why does it not occupy memory, we usually use an array to explicitly indicate the size of the a

Browse the previous article about cool shell today. So I checked the information and found out the "zero-length array", that is, the flexible array. The record is as follows. A zero-length array is generally found in a struct, and a zero-length array is directly declared. For example, char str[0];It cannot be compiled. On the Internet, the zero-length array is usually placed at the position of the last member of the struct, but I tried to put it in t

How to Write standardized, flexible, stable, and high-quality HTML and css codeGolden Law Always follow the same encoding specification. No matter how many people participate in the same project, make sure that each line of code is written by the same person.Syntax: 1. use two spaces to replace tabs. 2. the nested element should be indented once (two spaces); 3. for attribute definitions, make sure that all double quotation marks are used.

The traditional solution for layout, based on the box model, depends on the Display property + Position property + Float property. It is very inconvenient for those special layouts, for example, vertical centering is not easy to achieve.The Flex box model introduced in CSS3 is a new feature that lets you say goodbye to floating and perfectly vertically centered.Although the current CSS3 on the PC side of the compatibility is not so perfect, but on the mobile side has been basically implemented c

The simplest and most flexible javascript date-to-string tool functions I have ever seen We know that the Date object in javascript does not provide a Date Formatting Function. Converting a Date object to a format like 20:35:11 is a common requirement in projects. I recently saw a piece of code in our project, which is very short and shared here. Date. prototype. format = function (format) {var o = {M +: this. getMonth () + 1, // monthd +: this. g

PHP obtains the FILE path (flexible application _ FILE __). _ FILE __indicates the complete path and FILE name of the returned FILE. If it is used in a include file, the include file name is returned. Starting from PHP4.0.2, __file _ always contains an absolute path. In _ FILE _, it is the complete path and FILE name of the returned FILE. If it is used in a include file, the include file name is returned. Starting from PHP 4.0.2, __file _ always conta

Flexible background management rights based on MongoDB design MongoDB is a document-based NoSQL database that is now a community of fire, with a natural advantage in storing flexibility in the document (the same set can be any form of row data, and of course we're not going to rot with that flexibility:) ), with impressive performance and high availability of replica sets! This permission granularity exists in the scope and the individual concept, can

Best design: Allows users to freely control the text size of any page. Users in the browser can customize the default text size, if the use of PX, users themselves in the browser settings to change the text size, the page will not change. We cannot exclude visually impaired users (such as myopia) and older users will not do so.Using the REM unit of CSS3, the nesting problem of em relative to the parent element ratio is avoided, and PX units are added in order to be compatible with the lower vers

Flexible handling of mysql Data Import errors is often used to resolve SQL file import to the database. It may be the restoration of the database from the mysqldump script or the database migration. Such an SQL file usually contains many statements. If an error occurs in a statement, the entire import task is terminated. What should I do in this situation?
