class member function

Pay attention to this point Const object defaults to a local variable of the file When defining a non-const variable in the global scope , it can be accessed throughout the program, and we can define a non-const variable in a file,

ObjectiveC + + member functions are divided into static functions, non-static functions and virtual functions three kinds, in this series of articles, many mentions static and non-static does not affect the memory occupied by objects, and virtual

These two days I wrote a test of C + + exception handling mechanism of an example, feel a good demonstration of the role, posted here, to the C + + exception handling beginners to get started. This article is accompanied by C + + abnormal knowledge

Yesterday, the senior again out of the test test, let us implement similar to the string class of No mystring class, at first very headache, but really in the writing code when I was very excited to find that this process is really a very valuable

polymorphic The concept of polymorphism is a little blurry, and if you want to describe it in a clear language at the outset so that the reader can understand it, it doesn't seem realistic, so let's look at the following code: Routine 1#include

Sometimes we import C + + classes into lua, which makes it easy to get to C + + in Lua class, which is often used in game programming, this article simply introduces an implementation. 1. Lua an object-oriented implementation inside

class member Pointer This article mainly discusses the pointers of class members in C + +, which is rarely used and difficult to understand. If there are errors or omissions in the text, please point out, thank you. The need to use class member

1. precautions to compile the method see: http://blog.csdn.net/wangyaninglm/article/details/39997113   The following is the program code, online search examples: Note: 32-bit projects add 64-bit support (mainly depending on the version you compiled)

Yesterday colleagues let help write a small function, only found Cocos2d-x 3.0 and cocos2d-x 3.0rc0 difference is quite big.Find the label of this control, 3.0 more than the RC0 version of a creation function, more critical is that the label anchor

1, the introduction of the problem1). Observe the following first block of code:#include using namespace Std;class screen{public: void Test () { DUMMY_FCN (); } void Dummy_fcn () { }};This code compiles

Brief introduction:     The callback function is a C programming-based Windows SDK technology, not for C + +, the programmer can direct a C function as a callback function, but if you try to directly use the C + + member function as a callback

1 MFC overviewAs implies, the MFC application framework is based on the framework of MFC, the application framework of this program is built in the program structure of the organization is completely different from the previous Win32 SDK programming

Most applications use common inheritance for a single base class, but in some cases, single inheritance is not enough, and multiple inheritance must be used. C + + allows you to specify multiple base classes for a derived class, so that the

Window segmentation in peacetime in the use of a lot of, Windows Explorer, the code of the IDE (Visual stdio,eclipse) has a window segmentation, the following we start with a single document dimension to talk about how to split the

First, static data membersC + + allows you to define a data member of a class as a static member. A static data member belongs to a class, and the entire class has only one backup, which is equivalent to the global variables of the class and can be

1. Basic Requirements1.1 program structure analysis, easy to understand, the number of program lines of a single function cannot exceed 100.1.2 What are you going to do? It should be simple, straightforward, and code should be streamlined to avoid

C ++The member pointer is the most complex syntax structure. However, it is widely used in event-driven and multi-threaded applications to call-back functions. In multi-threaded applications, each thread calls this function by pointing to a member

In programming, we often encounter the requirement to call member functions through function pointers in a "class". For example, when a class is usedC ++When the sorting function qsort in the standard library requires a "comparison function" pointer

From http://blog.csdn.net/freeboy1015/article/details/7634950The fifth meaning of static in C + + is that class member functions that do not access non-static data members are not accessed with static adornments. This means that a static member

1 OOP Overview Object-oriented is based on three basic concepts: data abstraction, inheritance, and dynamic binding. Using data abstraction, we can separate class interfaces from implementations. Using inheritance, we can define similar types and
