A simple example of a Linux Java program communicating with a C language program through a socketthis morning, I experimented with a Java program communicating with a C language program through a socket. Because did not learn Java, so just write the C language side of the code, the Java side of the code is from the Web

sizeof result of the struct data structure, such as the following program:#include void main () { struct a{ char A; Short b; int c; }; " size of struct A =%d \ n " sizeof (struct A));}The output is: 8 bytes.If we make a slight change to the position of the variable declaration in the struct (without changing the variable itself), look at the following procedure:#include void main () { struct a{ short

In C language, you can use the static keyword in the global scope: variable or function modified by the static keyword, only in this ". c file "is visible, while in other ". file C is invisible. For example, if the static function func is defined in the global scope of t1.c,

The examples in this article describe DataBindings usage in C #. Share to everyone for your reference, specific as follows: In C # operation of the database process, for the general text control, such as Textbox,label, and so on, we assign value directly using a similar textbox.text=**** way to do, this way is indeed the easiest way in a sense, but for the more complex space, For

tree on G. The algorithm starts with u={u0} (U0∈V), te={}. Repeat the following actions:In all u∈u,v∈v-u edges (u,v) ∈e, an edge (u0,v0) with the smallest weight value is merged into the set TE, and V0 is merged into U until V=u.At this point, the TE must have n-1 bars, t= (v,te) is the minimum spanning tree of G.The core of the prim algorithm: Always keep the edges set in te form a spanning tree.Note: The prim algorithm is suitable for dense graphs, whose time complexity is O (n^2), its time c

These two days I wrote a test of C + + exception handling mechanism of an example, feel a good demonstration of the role, posted here, to the C + + exception handling beginners to get started.

The presence of C language pointers makes the control of hardware and the flexibility of C language greatly improved.However, there are many difficult problems in the use of pointers.#include #include//The function here is an example of a pointer doing a parameter, knowing that this feature can compensate for the ability of a

In the afternoon to engage in MVC and ExtJS date format conversion encountered problems that we have from. NET Server-side serialization of a DateTime object is the result of a string format, such as '/date (1335258540000)/' strings. The integer 1335258540000 is actually a number of milliseconds from 00:00:00 to this datetime intermediate interval of January 1, 1970. JavaScript uses the Eval function to convert this date string to a Date object with a time zone, as follows with var date = eval

Problem DescriptionTomorrow will be the English exam, Wowapps is Midnight Oil recite the words. Wowapps found the word difficult to recite, the back one forget. After careful study, Wowapps found that the reason why the word is difficult to recite is because of the appearance of a character, destroying the beauty of the whole word, resulting in poor memory. Wowapps decided to destroy these discordant characters on behalf of the Moon!! (Applause!!) But the exam has entered the countdown, and Wowa

An application example of indefinite parameter in C language: indefinite parameters as a special skill of the middle-C + + language was praised by many people, but in fact this technology has not been applied much. I don't see much application except formatted output. The main reason is that this technology is more cumbersome, side effects are more, and in genera

into three steps: server listening, client request, and connection confirmation. A server listener is a server socket that monitors the network in real time, instead of locating a specific client socket, but waiting for a connection. A client request is a connection request initiated by a client socket. The target is a server socket. Therefore, the client socket must first describe the socket of the server to be connected, point out the address and port number of the socket on the serv

This article describes the C language of the generic programming method, share for everyone to use for reference. The specific analysis is as follows: First, generics programming allows you to write fully generalized and reusable algorithms that are as efficient as algorithms designed for a particular data type. In C, this type of generic programming can be achieved through a number of means. Here's a meth

(1) if a C + + program uses a header file with the suffix ". h", then you do not have to declare the namespace in the program, only the file contains the header file, (2) the C + + standard requires the system to provide a header file without the suffix ". Instead of using the suffix ". h" in the header file, prefix c with the corresponding header filename in
