This article from: http://mail.ustc.edu.cn /~ Bywang/programm/vc/sx/8.html   Before reading this article, we assume that you have:1. Know how to create an App Wizard for a single document2. Familiar with C ++ classes, function overloading, and other

 The forced transformation of C-style is as follows: (T) expression or T (expression) // function-style) There is no essential difference between the two forms. CStyle transformation works well. However, such conversion characters can also be

After learning MFC for a while, I used to imitate other people's programs. I don't know why, but these problems must be solved later. It is always impossible to get through it in a confused way, so I searched some functions on the Internet and

C ++ virtual functions 1 #include 2 using namespace std; 3 class Base{ 4 public: 5 void m() 6 { 7 cout f();29 base->m();30 } The above is based on the Base class, And Sub derives the Base. At the same time, two functions f () and

Objective-c syntax (3): objective-c syntax Anonymous objects in oc Oc is rarely used here, because it is not suitable for the memory management of oc, but may appear in the interview test, which requires understanding. Do not write it like this in

I encountered a problem today. After debugging for a long time, I found that the misuse of class pointers and the fuzzy understanding of class pointers and class objects are the more basic things I have, the easier it is to have problems. Remember

Destructor usage:1. Each destructor (without virtual) is only responsible for clearing its own members. 2. There may be a base class pointer pointing to the case where it is indeed a member of a derived class.For the second case:Correct execution:

The first is the use of Mknod manual Create: # mknod the second is self - Create device node: using udev (Mdev) to automate the creation of device files, first of all ensure that Udev (Mdev) is supported and configured by BusyBox.Specific UDEV

Q: What is C-style conversion? What is Static_cast,dynamic_cast and reinterpret_cast? What's the difference? Why pay attention to it? A: The meaning of a transformation is to change the representation of the variable by changing the type of the

The example in this article explains the transformations between the base class and the derived class in C + +. It will help to understand the object-oriented programming of C + +. Note here: The premise of this example is that the derived class

Use standard C++ type conversions: static_cast , dynamic_cast ,, reinterpret_cast and const_cast .static_castUsage:static_cast (expression)The operator expression converts to a type-id type, but there is no run-time type check to guarantee the

Although the C language has been learned, but some of the basic C + + is not very understanding, but also need to master. Vaughn also began to talk about C + + design mode, must quickly see, or will be white nest drops money. For memory leaks, my

We know that in the same class you cannot define two functions that have the same name, the number of arguments, and the same type, or else it is "duplicate definition." However, in the inheritance hierarchy of a class, functions that have the same

Polymorphism is a basic attribute of object-oriented, including static polymorphism (compile phase) and dynamic polymorphism (runtime phase). Static polymorphism mainly refers to the polymorphism of different function parameters, which is a

From: http://read.newbooks.com.cn/info/50236.html The forced transformation of C-style is as follows: (T) exdivssion // cast exdivssion to be of type T Function-style forces the transformation to use the following syntax: T (exdivssion) // cast

Use the Standard C ++ type conversion characters static_cast, dynamic_cast, reinterpret_cast, and const_cast.   1 static_cast Usage: static_cast (expression) This operator converts expression to the Type-ID type, but does not check the runtime type

Statement by netmd: I am not original, from the Internet, and a collection of two posts. I personally think this is more complete. ---------------------------------------------------------------------- Q: What is C style conversion? What are

Class {......} class B: Public {.....} (1) A * pA = new B (2) B; A & RB = B; (1) is a base class pointer pointing to a derived class instance? What is the significance of doing so? What does (2) mean? What is the purpose and meaning? Please provide

Many books have discussed the issue of forced type conversion. The most detailed issue is the design and evolution of C ++, the father of C ++. The best solution is not to use a C-style forced type conversion, but to use the standard C ++ type
