C++

The content of this article is the key in C ++. Most people are confused about this content, but this content is the basis of programming and must be described in detail. Number representation In mathematics, numbers only have different numerical

In c ++, inline modifiers are introduced to solve the problem that frequently called small Han numbers consume a lot of stack space or stack memory.Many people may not understand what stack space is. In fact, stack space refers to the memory space

In order not to blur the concept, we will briefly describe it hereClass DecompositionIn the previous tutorial, we focused on class inheritance. The Inheritance feature is that the derived class inherits the features of the base class and expands the

In the previous chapter, we have already touched on the overloading of the incrementing operator. At that time, we did not distinguish the difference between the incrementing first and the latter, normally, we do not see the differences between ++ a

Preface To learn c language and c ++, you first need a development platform that provides exercises. For c ++, there are many tools and platforms available, including Borland's c ++ builder and Microsoft's Visual Studio series, they are indeed very

　IntroductionPointers are characteristic of the C/C ++ language, while array names are too similar to pointers. In many cases, array names can be used as pointers. As a result, many programsDesignThe person is confused. Many university teachers, in

I remember that when I first learned C ++, I liked to study APIs. At that time, my colleague had a master who wrote some code. When I was writing a program, the machine suddenly turned off! When I was wondering, I heard his smile!It turned out to be

Day 10: Enis and Enis allow programmers to access specific functions or classes without giving up private data security. To print data members in a class using a print function, either a function is a member of the class or a friend function. Note

Why EXTERN?Global variables (external variables) are defined outside the function. Their scope is from the definition of the variables to the end of the program file. In this scope, global variables can be referenced by each function in this file.

Q: How do I use dynamic memory allocation and pointers? With new, the returned memory is allocated from the so-called heap (heap), that is, the memory area managed during the C ++ runtime. How can this problem be accessed? Is to use pointers, for

Situ zhengmei Stack objects are equivalent to local objects, and stack objects are equivalent to objects that can be shared with functions or statement blocks. Stack objects are automatically destroyed after the statement block is executed, and the

Std: bind is defined in 1 #include   There are two types of statements: 12 templateclass F, class... BoundArgs> unspecified bind(F&& f, BoundArgs&&... bound_args); And 12 templateclass R, class F,

Class AObj; Typedef int (AObj: * pfun )(); Pfun pf_protected1 = NULL;Pfun pf_protected2 = NULL;Pfun pf_private1 = NULL;Pfun pf_private2 = NULL; Class AObj{Public:AObj (){}; Static int a_static_fun (){Pf_protected1 = & AObj:

The original question titled A game company is as follows: write a thousand-bit separator algorithm, and the function prototype is char * format_thousands_separator (unsigned long val). The expected effect is 1. the user does not need to release the

We have discussed how to initialize the D3D11Device device initialization and so on. The drawing figure mentioned here will be extended in the project of the previous article and drawn on the screen. The smallest unit in 3D rendering is a triangle.

  The reinterpret_cast operator is used to process conversions between irrelevant types. It generates a new value, which has exactly the same bit as the original parameter (expressoin.   What is an irrelevant type? I have not figured out, but I have

What is pointer?The memory address of a variable or function of the pointer. It is an unsigned integer. It is a 32-bit, 4-byte system addressing range. Pointer variable:The variable that stores the address. In C ++, the pointer variable makes sense

This Code uses the WinInet class to directly open a session, read and save the webpage. BOOL CDdDlg: GetSourceHtml (CString theUrl, CString Filename){CInternetSession session;CInternetFile * file = NULL;Try{// Try to connect to the specified URLFile
