What is value semantics?Value sematics indicates that copying an object is irrelevant to the original object, just like copying an int. The built-in types of C ++ (bool/int/double/char) are both value semantics, complex
The value semantics corresponds to "object semantics/object sematics", or "reference sematics". Bec
C + + compilation takes a lot of effort to make the use of class and the original class (primitive types) consistent. For example, an array application:A a[100] ;//A is classint b[100] ;Although a is an object of a user-defined class, it is no different than an array of integers. Let's look at the semantic differences.A is the Pod class (a class with full value semantics)If a is a PODwith value semantics

The semantics of HTML tags
Web standards are now popularly called "div+css" or "layer layouts." I have no objection to this Bingyi. But it's a myth: a lot of the use of div tags as a structural element. In fact, this is a more advanced div abuse (Jeffrey Zeldman mentioned in the book "Web Refactoring").
HTML provides us with a fairly rich tag, each of which has its own meaning. I think at design time, in addition to following HTML syntax, you should t
"=" as the right value. But the assignment object is I or J, both are lvalue values.Before c++11, the right value cannot be referenced, and the maximum is to bind a right value with a constant reference, such as:const int a = 1;Syntax symbols for left and right values:The declaration symbol for the lvalue is "", and for the left value, the declaration symbol for the right value is "". However, if a temporary object is passed to another function through a function that accepts an rvalue, it beco

Semantics is actually a string assigned to the shader input and output, which expresses the meaning of this parameter. These semantics allow shader to know where to read data and where to send it. After DirectX10, there is a new semantic type, the system

Another important aspect of separation structure and performance is to make semantic markup to construct document content. The presence of an XHTML element means that part of the tagged content has a corresponding structural meaning, and there is no reason to use other tags. In other words, don't let CSS make an HTML element look like another HTML element, such as

Pointer and its semantics and Application
This article is an appendix to the "C ++ from scratch" series. As friends once and again think that the pointer in the "C ++ from scratch" series is too simple, and the various concepts proposed are mixed, in addition, pointer is rarely used as an important concept in C ++, therefore, this article focuses on the basic concepts of numbers, addresses, and pointers proposed in the C ++ from scratch series, and pr
For example :. w100 {width: 100px ;}. w200 {width: 200px ;}. w300 {width: 100px ;}. m100 {margin: 100px ;}. m200 {margin: 200px ;}. m300 {margin: 300px ;}...... My understanding is: Since labels need to be semantic, the class id should also be semantic rather than completely serving the style. It is very convenient to do so, for example :. w100 {width: 100px ;}. w200 {width: 200px ;}. w300 {width: 100px ;}. m100 {margin: 100px ;}. m200 {margin: 200px ;}. m300 {margin: 300px ;}......
