Ten years did not write C, this can be said to re-learn, the bottom of the program is to change from W.richard Stevens's masterpiece-Networking apis:sockets and XTI, for two reasons: (1) In my development environment scientific LI Nux 7.0 on the

1. IdentifiersIn the C language, symbolic constants, variables, arrays, functions, etc. all require a certain name, and we make this name an identifier.2. The principle of naming identifiersNaming rules:1. Can only be composed of letters, numbers,

A few days ago to see such a blog " Those years, we read the professional books ," There are many people think very good books, plus their own in the C + + project also read a lot of books, feel not all the books are worth spending time to see,

Learning Summary1, the buffer is divided into full buffer (fully buffered) I/O and row buffer (line-buffered) I/O. For a fully buffered input, it is emptied when the buffer is full (the buffer content is sent to its destination). This type of buffer

Not much to say, the program is very simple, is the collection of data to sort, but the use of the knowledge point is still more, Daniel do not spray, I would like to dedicate to beginners! Go directly to the program!namespacedemo{/// ///Demo:

C Name Decoration rules1. For functions that use the __cdecl calling convention, add a dash before the function name, regardless of the parameter and return value.2. For functions that use the __fastcall calling convention, add an @ sign before and

Title: Reverses the list in O (n) and returns the head pointer of the inverted list.Analysis: The problem of solving linked lists must first consider the non-empty problem, but also pay attention to the location of termination., when reversed,

The oldest sequence and problems are very easy:is an array, which is the maximum value of the continuous segment and the whole sequence. To find out the value.First, the most complex: O (n3)Directly on the code, very easy: main.cpp// sumsequence///

1, the string problem formal definition: The assumption that the text is a length of n T[1..N], and the pattern is an array of length M p[1..m], where m2, Method: First preprocessing based on the pattern, and then find all valid offsets

The cache is primarily intended to improve the reading speed of the data. Because of the traffic bottleneck between the server and the application client, when reading the bulk data, using the cache to serve the client directly can reduce the

1. Add a NamespaceSystem.IO;System.Text;2. Read the file(1). Use the FileStream class to read the file, convert it to a char array, and then output.        public void read ()          {                      byte[] byData = new byte[100];            

the previous ExecuteReader () method, which involves the command object, returns a DataReader object, so we'll describe the Datareade object in detail. The following example uses the same data table as in the previous article for the Manager data

We hope for a universal solution, but the real situation is always bad. In the world of software programming, technology dispersion is particularly serious, and not to speak of the advantages of various languages can not be integrated, in a single
