I. Moving lvaue and rvalue has an interesting phenomenon before c ++ 11: T & points to lvalue, const T & points to lvalue or rvalue. However, there is no reference type, which can be restricted to pointing only to rvalue. at first glance, this does

. During the value transfer process, parameters in the form of the called function are processed as local variables of the called function, that is, the memory space is opened in the stack to store the values of the real parameters put in by the

Recently, cocos 2dx has returned to the c ++ era. Let's take a look at it and consolidate your knowledge.   Youyuan is designed to increase the running speed of the program, but it destroys the encapsulation of the class. Youyuan function:

Class friends. C ++ proposed the concept of youyuan to address the needs of efficiency. As long as you declare an out-of-class function as a friend of the class, you can directly access any member (public, protect, private) in the category) This is

1. Static members Static members belong to the class, not the object. But it is shared by all objects. Because static members do not belong to all objects, no memory space is allocated to static members during object initialization. Therefore, in
