Preface:Eigen is a C + + Template library for linear arithmetic, including: vectors, matrices, open source, and related algorithms. Powerful, fast, elegant and multi-platform support, you can use this library to facilitate the operation of some

1) The key to "polymorphic" is that when a virtual function is called through a base-class pointer or reference, the compile-time is not sure whether a function of the base class or the derived class is being called.The runtime is determined-this is

First, Introduction The Lzlib compression library provides LZMA compression and decompression algorithms in memory, including integrity checking of the data. The compression format is Lzip Second, installation

To print a report operation steps:1 Creating DataSet Datasets2 Creating the RDLC report file3 Creating a ReportViewer view in a form, specifying a specific data source4 assigns a value to the Datatablede object in the dataset.Reference code:private

#include #include #include typedef struct queue{int * pbase;// Pointer to array first element int front;//queue header element subscript int rear;//Queue trailing element subscript}queue;/*** Initialize queue, implementation queue array length is 6

Use fragmented time, first of all the knowledge points to be prepared in advance. Recently busy, preparing an article to bind C + + objects into Lua. But, do not want to easily start, hope to do enough preparation.This translation comes from

C source program is composed of functions, and there is only one main function (main () function).First, the function1. The writing format of the Custom function:返回值类型 函数名(参数类型 形式参数1，参数类型 形式参数2，…){ 函数体}For example:1Include 2 voidtest ();3 4

When copying an object, do not forget its every ingredientThe author of this section reminds us that in the case of multiple inheritance of the copy or copy assignment operator=, it is important to consider the initialization of the base class

function templates are generic function descriptions, that is, they use generics to define functions, where generics can be replaced by specific types, such as int or double. Passing a type as an argument to a template enables the compiler to

Don't let exceptions escape destructorsWhy don't you let the exception escape the destructor, and what are the problems that the exception will cause? It is clear that anomalies can lead to ambiguous behavior.The following code:Destructors are

Retrieves a string that conforms to the phonetic index in the specified string list cnstr Kanji string corresponding to the first letter of the pinyin string public static string Getspellcode (String cnstr) {String strtemp= "";int ilen=cnstr.length;

Recording I generally prefer the MCI approach and of course there is another way and DirectSound but it's going to be a lot of trouble.But it has a feature that makes me feel better, first you can choose the source of recording equipment, second it

Generics: That is, a parameterized type is implemented to manipulate multiple data types on the same piece of code. Generic programming is a programming paradigm that abstracts types using "parameterized types" for more flexible reuse.Overview of
