value reference

The reference folding principle and perfect forwarding are related, it can be said that the latter is based on the former characteristics of some of the implementation, specifically to look at.To understand the perfect forwarding, you need to

Objective In a project sucked in in order to use shared memory and custom memory pools, we define functions ourselves and MemNew automate constructors for non pod types within functions. Call the custom function where you want it MemNew . This

Objective All the means are to solve the existing problems. Std::move and Std::forward are the characteristics of c++11 in order to solve the problems left in c++98/c++0x, although it is more complicated from the understanding, but it is a better

[C ++ 11] _ [primary] _ [left reference declaration and right reference Declaration]Scenario: You can see the right value reference in the remove_reference struct &. What is the use of the right value reference here? We often find that int & and int

Reference the right value of C ++ 11 and std: move      New Type:   What are int and int? All are types. Int is an integer type, and int & is an integer reference type. Int & is also a type. Two quotation marks (&) are a new reference type proposed

Problem leads Today, Aikilis asked me two questions:1 is the code below legal? (i > 0 i:j) = 1; 2 How to use a prototype for Quest (Bool,type,type) function to achieve the three-character function. On trial, the answer to the first question is yes,

In C + +, there are three major function copy controls (copy constructors, assignment operators, destructors), while in c++11, move constructors are added to move assignment operators. I would have ventured to name them six functions well. first,

1. What is copy control of a class? When we define a class, we usually need to consider the following items to make the class type we define as easy as the built-in type (char, int, double, etc: Q1: use this class object to initialize another object

The reference cannot be empty Cannot define a reference that does not refer to anything -int& r = NULL; Error But "Wild references" or "dangling references" do exist. -int & r = *new int (1); ++r; cout Delete &r; ++r; Not defined The solution

1. Scope for statement C++11 introduces a simpler for statement that can easily traverse all elements of a container or other sequence Vector VEC = {1,2,3,4,5,6}; for (int X:vec) { cout 2. End return type To introduce a trailing

Vector is Cocos2d-x 3. X releases the list container, so what it can hold is the object pointer created by REF and subclass, where T is the template, indicating the type that can be put into the container, in the Cocos2d-x 3. in x, t indicates the

The first thing we need to know is that when you return a value, a pointer, a reference (less than eight bytes can be taken out of the register) It is important to note that, for example, the address of a local variable is returned in the following
