There are many reasons to explain why we should be clear and readable.Program. The most important thing is that you only write the program once, but will read it countless times in the future. When you look back at you the next dayCodeYou are about to read it. When you show your code to others, you must read your code. Therefore, it takes a little more time to write and you will spend a lot of time reading it.
Let's look at some basic programming skills:
Keep the method as short as pos
Now, we use the Java language to write for the Palm OS Program The fields are not completely unified, and there are also many differences. Currently, there are several available application interfaces on the market, each application interface provides different access permissions to the current Palm OS application. Perhaps everyone is most familiar with Sun Microsystems, but it is not the only product that can write programs for Palm OS. This part of

Terminal windows and tools are often used for graphical operations on the centos system. However, opening these programs on the GUI is often complicated, for example, in a command terminal, sometimes you need to open another program when the original program runs. It is necessary to call out another terminal program. In this case, it is very convenient to set the shortcut key for the terminal command. The following describes how to set the shortcut ke
I reviewed the Linux socket programming, wrote the simplest server and client programs, and passed the test. The server-side programs adopt the loop and busy waiting mechanism, which will be changed to multithreading and thread pool mechanism later.
Server programs

Client Program

Note:
These two programs should be run on the same machine. You need to create the/home/rangaofei/c_test/directory in advance.
This afternoon I learned about socket communication programming, read a book, and find an online explanation. Although it is still dizzy, the small experiment is still successful, and I plan to study it further tomorrow.

In the article "Making crawler/spider programs (C # Language)", we have introduced the basic implementation methods of crawler programs. We can say that crawler functions have been implemented. However, the download speed may be slow due to an efficiency problem. This is caused by two reasons:

In the C language, you can call system commands and get output with the systems function, and output redirection can also save the output of the program execution to a file for use, but it is not very convenient to use. Here I introduce the implementation of Python and go language, you can save the output of other programs directly into a variable for the program to use.
