. Generic structureIn fact, the generic structure and the generic class are almost identical, except that the generic structure has no inherited attributes: NET platform provides a generic structure that is (nullable type) nullableInt? X1; NullableIn the above example, X1 and X2 are defined as equivalent.Non-null types can be converted to nullable types. (Always successful and can be converted implicitly)Nullable types can be converted to non-empty types. An exception is thrown when the value of

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

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

Direct3D to update the entire display (because the function can show only a portion at a time), as shown in the following code:g_pd3ddevice =pre-initialized device objectif (FAILED (g_pd3ddevice->present (null,null, NULL, NULL))) { // Error occurred}That's it! 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.============

PrefaceBecause the company needs to do a Linux under the development of QT, coupled with direct contact with some QT, then began to cramming.Previously useful Qt wrote a 2048 game, about 3 April, that will be 2048 positive fire, think of oneself in the computer also did a ~ then silently wrote a, the interface is ugly, but perfectly formed ~ next time thinking and some code again induction, and then write to the blog.Although writing a small thing, but the foundation is still very thin, so in or

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

.? 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

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
