During kernel, we noticed that some functions will add _ attribute _ (unused )),Relevant explanations are found in the GCC manual:Unused: This attribute, attached to a function, means that the function is meant to bePossibly unused. GCC will not

C ++ inherits the calling sequence and virtual destructor of the destructor in the destructor. First, let's talk about the constructor. We all know that the constructor can call member variables, and the Child class in inheritance is to turn the

Synchronous Implementation of threads in Android C ++ and android threads Preface In Android C ++, thread synchronization mainly encapsulates the mutex and condition of pthread. So before learning, we recommend that you first understand the

C ++ experience and experience C ++ experience: I. constructor is never called a virtual function: In the simplest way, the C ++ object model manages virtual functions based on the virtual function table. Therefore, when calling a virtual function,

C ++ Primer Plus learning note-taking class initialization sequence base class constructor, destructor and operator functions operator = cannot be inherited by the derived class; then, when creating a derived class object, how do I call the base

C # differences with C and OC, Actually, those familiar with these languages know that these languages are completely incomparable. Due to work needs, it is necessary to revisit the C # Language recently, which will inevitably be affected by the

C/C ++ basic pen question 1.1.2 (solution of operator 10) and 1.1.2 I wrote an irresponsible blog post in the previous section and was trampled on it, causing a little loss. In fact, it is really not good to simply ask questions, because a great

1. When passing a pointer, we can use the pointer to modify the content it points externally. However, it is impossible to modify the object pointed to by the external pointer. For example, if an external pointer is passed to the function to

The default value is private inheritance. The constructor initialization expression table allows you to explicitly call the constructor of a member object. The built-in type can be initialized like an object with a single constructor. Such as
