The metadata mode is a design mode that prevents the appearance of a large number of identical or similar objects. Generally, the objects that appear cannot be the same. They may be very similar, but some of them may be in different States, in this

C call C ++ Link Library: 1. Write c ++CodeWhen writing a function, you must add an interface to C, that is, extern "C" 2. Because C cannot directly call a function in the form of "class. function", C ++ needs to write an interface function for

1. Int sprintf (char * buffer, const char * Format [, argument]...); For example: CPP Code IntSS; CharTemp [64]; String STR; Ss = 1000; Sprintf (temp,"% D", SS ); String S (temp ); //

I searched the internet for a long time and used 5 or 6CodeIt's always a waste. They are all under the guise of resumable data transfer ~~~ Finally, we returned to the first mydownload. I would like to express my sincere thanks to this anonymous

1. Replace # define value with Const.2. Const in C ++ is an internal connection by default. (C by default, const is an external connection. Extern must be used if an external connection is to be reached in C ++. )That is to say, const is visible

Two rtti usage methods:1. The first type is typeid (), which is similar to sizeof and looks like a function, but is actually implemented by the compiler.The typeid () parameter is an object reference or pointer that returns a reference to a constant

From: http://blog.csdn.net/lai123wei/article/details/6933340     ConstIt defines the static value that is often assigned during object initialization. It cannot be changed later. It is a compilation constant. StaticDefines static variables.

Macros should never be used. Only inline functions are used. Any function defined in the class automatically becomes an inline function. You can also use the inline keyword to convert functions defined outside the class into inline functions.

Reference is like a constant pointer that can be automatically referenced indirectly by the compiler. It is usually used in the parameter table of the function and the return value of the function, but can also be used independently.When a reference

From: http://blog.csdn.net/lai123wei/article/details/7321575 1. What are the differences between static and non-static variables? Static variables : Static variables are declared using the static modifier, which is created when the class

In the following cases, you need to apply a reference to a Java object in a local method to convert data types: 1) in the Java method, pass the parameter to the local method. 2) create a Java object in the local method. 3) return the result to

A very simple CSV file read/write class.   View code Using System; Using System. Collections. Generic; Using System. IO; Using System. text; Namespace Csvdemo{ ///   /// Csvutil is a helper class handling CSV files. ///  

Back to directory The question is very interesting. In the C # world, there is an implementation called "display implementation", which is actually an interface implementation method. Generally, all the implementations we use are implicit

The "inheritance" feature of C ++ can be improvedProgram. Because "inheritance" is too useful and easy to use, it is necessary to prevent the misuse of "inheritance ". We need to set some rules for "inherit: 1. If the classA And classB

1.A Brief Introduction to youyuan Functions 1.1 why do I need to use a friend function? Reduces system overhead and improves efficiency when data is shared between classes. If a function in Class A is to be a member of Class B (for example, the

1. Why should we introduce Virtual inheritance? Virtual inheritance is a special concept in Multi-inheritance. The virtual base class is designed to solve multiple inheritance issues. For example, Class D inherits from Class B1 and B2, while Class
