  Connect Step 5: Learn multiple operation commands   To avoid repeated operations, vi has designed multiple operation commands: Operation count + operation command. This greatly improves the editing efficiency.   Example 1: delete 50 rows. We can

Previous: http://www.bkjia.com/kf/201205/130088.htmlNow let's talk about file operations and reading files in byte. It's actually very simple. I believe everyone will talk about them separately. Otherwise, everyone will not be in the mood to read

Nested Functions, also known as closure, belongs to the concept of functional language and has always thought that closure is not supported in C. Now it seems that I am wrong, but it is not supported in C standard, but GCC supports it.   Since GCC

/*Once wa n times, the error occurs at ① and must be supplemented at ②.*/# Include # Include Const int nmax= 50000;Struct BigNumber{Int data [nMax];Int len;BigNumber () {len = 1; memset (data, 0, sizeof (data ));}BigNumber & operator = (const char *

From the perspective of the name, the function pointer knows that it is also a pointer, a pointer pointing to the function entry address. Let's take a simple example to see the usage of the function pointer. 1. Call a function through a function

Yesterday, xiaowu asked me to help him write a program about the Gauss elimination method. Before that, he seldom wrote such a program related to mathematics. So he decided to give it a try, here I want to demonstrate a programming method. I used to

Volatile is a type modifier (const is also a type modifier). It is designed to modify the variables accessed and modified by different threads.Role of volatile: as a command keyword, make sure that this command is not omitted due to compiler

The cocos2d-x has a problem that even if the CCScene operation is paused, the touch is still valid and some menus and buttons are still triggered. So sometimes we need to manually shield the touch, especially when the billing screen is popped up or

Note: The title "class" does not necessarily refer to object-oriented classes, but generally refers to code files with specific functions)I have a habit of writing code. At the beginning of a project, I will first create a "tool code" Directory,

Recently I have had a lot of ideas and want to thoroughly understand all the things I have used, so that it will not become the so-called "samples are similar ". I'm a newbie. Please let me know if you have any problems. Thank you! In fact, I

Some files of the application need to be permanently stored locally so that the application supports offline functions. However, these files do not contain user data and do not need to be backed up. How to prevent these files from being backed

The previous STL container deletion operation continued, and STL was easy to use, as well as automatic memory management. Combined with appropriate generic algorithms, the programming efficiency was greatly improved, as a result, we use our programs

The previous article on Linux multi-process development explains the fork () creation process. This article describes the vfork () creation process in detail. Vfork () and fork () are different: 1. vfork () is the same as fork (). It is called once
