occupied by that object for a long time. This can be problematic if the resources used are important. (There will be a solution in the back). 4. Static and instance class functions (1) Classes also have static members, which can be shared among instances of a class, and do not even need to instantiate objects when using static members. UML Diagram notation: In a UML diagram, a static member of a class is represented by an underscore. (2) Static constructors When you use static members in a cla

default is private. For example, in the class clock declaration, if the public is not there, then both the SetTime and Showtime functions are private by default. Private type members can only be accessed by member functions in this class and cannot be accessed externally. Hour, Minute, and second are all private type members in the Clock class.8. A simpler member function of a class can also be declared as an inline function, which, like a normal inline function, inserts the function body of an

In order to create more realistic scenes, you use a number of different vertex caches to draw a variety of mid-range objects in your world. Another way to improve the authenticity of your graphics is to use texture mapping.============

Personally think this is a pretty good tutorial from C language to Linux system development, this is a two online document. One of them is "how toThink-a computer scientist:learning with C + +" author Allen B. Downey. The original book was issued by Green Tea Press and can be downloaded from http://www.greenteapress.com/. Another is: "Programming from t

method is a static method, which is part of a class, but is not actually placed in the source code of the class. Suppose that the money class needs a method Addtoamount (decimal amounttoadd). However, for some reason, the original source code of the program can not be directly modified, all that must be done is to create a static class, the method Addtoamount () Added as a static method. The corresponding code is as follows:Namespace Wrox{public static Class Moneyextension{public static void Ad

C ++ programming ideology learning notes-constants 1. Use the global const1. The use of const has two effects: one is to generate a compile-time constant and the other is a runtime constant.As a compilation constant, it is mainly used as a value substitution, that is, to replace the # define constant definition in C, w

Yesterday, I looked at the "C # Advanced Programming" in the object and type chapter, found that there are many omissions do not understand the place to re-understandFirst of all, what is the object, my personal feeling is: in the programming world, a program is the processing logic of a thing, and the object is the abstract concept of this logic.For example: We

Re-learning C # advanced programming (generics and arrays ), I have been busy with my work some time ago, so I didn't write it casually. Now I want to continue. I re-read the generic and array Chapters two days ago. Let me briefly explain my gains. Generic We know that arrays are a batch data format, while generics are actually a custom batch data format, whe

derived class defines a function void P (); void P () is also a virtual function because the function has the same name as the virtual function of the base class and is called in the same form . It is strongly recommended that you add the virtual keyword before the derived class void P ().If the function in the derived class is void P (int x=1); In this case, the P function is not a virtual function and masks the virtual functions of the base class called P ().We analyze each of the 4 calls in

Learning C # advanced programming together 3 -- Operator Overloading, Operator. C ++ developers should be familiar with this concept, but it is brand new to Java and VB developers. For some calculation between values, if you use a method to specify the operation rules, it will be cumbersome, then you can use the operat

.? Another garbage collection algorithm is a "reference count", the idea of which is to track the number of times all values are referenced. The JavaScript engine is no longer using this algorithm, but this algorithm can still cause problems when accessing non-native JavaScript objects such as DOM elements in IE.? The reference count algorithm causes problems when there is a circular reference phenomenon in your code.? Removing a reference to a variable not only helps eliminate circular referenc

C #. Net parallel and multi-threaded programming Task learning records !, Difference between Task and Thread: 1. The task is structured on the thread, that is to say, the task should be finally thrown to the thread for execution. 2. Tasks and threads are not in a one-to-one relationship. For example, opening 10 tasks does not mean that 10 threads will be opened.

3.8 Extension methods An extension method is a static method, which is part of a class, but is not actually placed in the source code of the class. For some reason, the original source code of the assembly cannot be modified directly.
