. That is, in cshell, a string is any Character Sequence in two double quotation marks.
After lexical processing, it is the corresponding syntax. the lexical analysis result is the token sequence, which is the input for formal syntax analysis. That is to say, syntax analysis is similar to lexical analysis, except that the input of lexical analysis is a single character sequence and the output is a token sequence. The input of syntax analysis is a token sequence, and there may be many types of o
CentOS7 Vim Automatic completion Plug-In ---- YouCompleteMe installation and configuration, youcompleteme
Recently I installed CentOS7, a new system. to configure the encoding environment, I used neocomplcache + code_complete + omnicppcomplete to write programs using Vim. However, when searching online, you can see YouCompleteMe, which means YCM is better. I also like new things, so I decided to install YCM. However, the installation process has encountered many pitfalls. The online tutorials ha

How does python work?
We'll start with an advanced interactive interface to see how Python works inside. When you enter a line of code in the python interaction interpreter and then run it, what does the interpreter do?

I haven't written a blog for a long time. One of the reasons is that I recently used Evernote to record what I think and what I think. Another reason is that after csdn disabled the blog writing function of live writer, I am not very interested in writing in the csdn webpage editing box. Once the crash occurs, all the writing is lost, and the phone is hard to write. The title of csdn is "the largest Chinese IT community in the world, providing the most comprehensive information dissemination and

of the great benefits is that when the compiler version is updated, the newly added warnings are included in the-wall without any modifications to the project, and new warnings can take effect. This immediately detects the potential pitfalls of the same project due to a compiler version update. Another more important reason is that: The Xcode UI does not provide all the warning =_=| |. Just mentioned, it is important to note that-wall's name is all, but it is really just a confusing word, in f
The actual situation of automated software testing
The term automated Software testing (automated Software testing,ast) draws many different meanings from members of the software development and testing community. For some, this term may be the meaning of test-driven development or unit testing, but for others it may mean using capture/recording/playback tools for automated software testing. The term may also mean using scripting languages such as Per
