concept of algorithms. Then C is not important, wrong! Algorithm is the basis of programming, good design if there is no good algorithm, just as not. Moreover, "C plus good design" can also write very good things.This time to share with you is my little text on the use of functions in C, I hope to help students with doubts better use this powerful language features.In high school, we all asked for the expression of mathematical function, in fact, the

A lot of people are asking me in the tech League, how to learn a variety of programming languages; Of course everyone has everyone's learning methods, I personally think that doing anything interest will determine your motivation to learn, once from the ASP to PHP to the current Java development, all the way to learn to actually find programming these things pay

calculation, so for large-scale problems. There is the advantage of recursion, which is also the core of dynamic programming algorithm.This paper determines the three elements of dynamic programming, and the whole solution process can be described by an optimal decision table, and the optimal decision table is a two-dimensional table. When a row represents the stage of a decision, the column represents the

, ActiveX now has the ability to use across platforms. In fact, ActiveX means "If your program is connected to its working environment, it can go to the Web page and run in an ActiveX-enabled browser" (IE solidifies support for ActiveX, and Netscape needs a plugin). So, ActiveX does not restrict our use of a particular language. For example, let's say we're already an experienced Windows programmer who can skillfully use languages like C + +, Visual Basic, or Borlanddelphi to create ActiveX almo

Function-Type programmingThe recent study of Python has been a bit of a snub, and the recent learning attitude and learning efficiency is really bad, and the current condition is improving.Today, I took a brief summary of the functional programming of Python, which I have previously learned, and share it with you, and also welcome and thank you for your comments.

as $*, but with quotes , and returns each parameter in quotation marks. The $-displays the current options used by the shell, as is the SET command function. $? Displays the exit status of the last command. 0 indicates no errors, and any other value indicates an error. In the afternoon to organize the two blog, is the Linux shell script based on the theoretical study finished, more details only when we met in slowly pondering it.

this problem is: The main class file you have created is not placed under the compiler default access path, The workaround is to refactor the program's compilation path.A shallow copy and a deep copy are known after class through access to information. A shallow copy is a bitwise copy of an object that creates a new object with an exact copy of the original object's property values. If the property is a base type, the copy is the value of the base type, and if the property is a memory address (

number of clusters, you can merge a two clusters, the choice of two clusters generally have two quantifiable methods: merging the nearest centroid, or merging two to make SSE The center of mass with the smallest increment.?Two points\ (k\)Mean value algorithmIn order to overcome the problem that the k\ mean algorithm converges to the local minimum value, someone proposes another algorithm called the mean value of the binary \ (k\) . The algorithm first takes all the points as a cluster and then
