A variable that is defined as volatile means that the variable may be unexpectedly changed so that the compiler does not assume the value of the variable. Precisely, the optimizer must carefully re-read the value of the variable each time it uses

Recently we have put together the whole project, the project is more complex. Because we do the retrieval system, so we use ASP. NET (C #), but the implementation of the algorithm is in MATLAB, so we have to use MATLAB to generate dynamic link

PDF is a more common format that is relatively stable to office.The easiest way to do this is txt, which is easy to read and write.But the PDF format is too troublesome, according to read TXT, can only get garbled, write not even think about

Reading and setting the XML configuration file is the most common operation, try a few C + + XML parser, personal feeling tinyxml is the most comfortable to use, because its API interface and Java is very similar, object-oriented very good.TinyXML

Java source code to C # five best toolsChszs, reprint need to indicate. Blog home:Http://blog.csdn.net/chszsFor some purposes, you may encounter the task of converting Java source code into C # source code. If you are understanding the source code,

Although function pointers are widely used to implement function callbacks, C + + provides an important way to implement callback functions, which are function objects. A function object (also called a "operator") is an ordinary class object that

1. What is a function any C language Program is composed of one or more program segments (small programs), each of which has its own function, which we generally call " functions ". So, you can say that the C language program is composed of

Clause 1:c++ is a language systemThe C + + language as a mature and complete language system, rather than simply the extension and extension of C. Because of its wide range of features, such as object-oriented, template, standard library,Generic

In fact, we have seen a number of standard-type data conversion between C + +, this form is used in the program to convert a specified data to another specified type, that is, a cast, such as: int a = INT (1.23), the effect is to convert 1.23 to
