Previous review

The previous section describes the basic environment configuration of C Programming in linux and the selection of related tools.

But we can use vim for 10 Daniel and 9 Daniel. In linux, do not rely on the graphic interface to play c. Okay, say goodbye to Ide. The command line is the king of c.

In this article, I would like to thank Sun He for his technical support and the loving c-bull.

Vim plug-ins (provided by Sun He) are mostly used in this article at http://www.vim.org.

 Pointer string

　　Since I have never played c since graduation, I have said that pointers are the focus of c. But as an address variable, why not directly operate on the variable itself. At the end of this article, we will announce

Vim configuration file

~ /. Default configuration file of vimrc
~ /. Vim/plugin/directory of users' default script files
~ /. Vim/ftplugin/directory for storing script files of the user's default file type

Test vim

Run the vim command as root on the terminal to display the vim homepage.

: R filename reads the content of a file and writes it to the current editor.

Press I to enter the insert mode

After editing: w save

After editing, Press esc to exit insert mode and enter normal mode.

Enter sh to go to shell.

Compile and run

Text Information Configuration

Set nu (written to the configuration file. vimrc) displays the row number.
Ctrl-g (use commands in normal mode) to display the file information and the current line.
Statusline. vim (plug-in) adds the bottom status bar.

Code indent Configuration

Filetype on (written to the configuration file. vimrc) makes vim sensitive to the file type.
Autocmd FileType c, cpp, h: setlocal cindent cinoptions =: 0, g0, t0 (written to the configuration file. vimrc) to set the c indent style. For details, see h cinoptions-values.
Autocmd FileType c, cpp, h: setlocal et sta sw = 4 sts = 4 tabstop = 4 (written to configuration file. vimrc) sets the indentation distance to four spaces.
= (Use commands in normal or visual mode) typographical code according to the indent style.
<(Use commands in visual mode) indent to the left.
> (Use commands in visual mode) indent to the right.

Syntax highlighting

Filetype plugin on (written to the configuration file. vimrc) the syntax highlighting plug-in for various languages has been added to the installed vim. You only need to open the plug-in related file types.

Quick Positioning

Gd (use commands in normal mode) jumps to the local variable definition.
GD (use commands in normal mode) jumps to the global scalar definition.
* (Use commands in normal mode) search for and jump to the word where the cursor is located.
G * (use commands in normal mode) is similar to *, but the search target does not contain the \ <and \> word boundary symbols.

G # (use commands in normal mode) function is close to #, but the search target does not contain the \ <and \> word boundary symbols.

Mark location

M {a-zA-Z0-9} (using commands in normal mode) makes a tag at the current position, marking a name that can use any character between a-z or A-Z, such as entering ma, is to mark the current position as. Note that a-z is a single file tag and cannot be used across files, while a A-Z0-9 is a global tag and can be used across files.
'{A-zA-Z0-9} (use command in normal mode) jumps to the tag of this file.
: Marks [{a-zA-z0-9}] (use command in normal mode) to view the content of the specified tag, view all without writing a tag number.
: Delm {a-zA-z0-9} (use command in normal mode) to delete a tag.

Full-text search

Ctrl-w o (use commands in normal mode) only displays the current window.

Function list
Taglist. vim () List ins.
Let Tlist_Use_Right_Window = 1 (written to the configuration file. vimrc). If you want to display the list on the right, add this configuration. The default value is left.

Ndd // Delete n rows including the current row down
U // undo the previous operation
U // undo all operations on the current row

Search:

/Vpser // search for a vpser string under the cursor
? Vpser // search for a vpser string from the cursor
N // search down the previous search action
N // search for the previous search action

Jump:

N + // jump n rows down
N-// jump n rows up
NG // jump to the row whose row number is n
G // jump to the bottom of the file

Set row number:

: Set nu // display the row number
: Set nonu // undisplay the row number

Copy:

Yy // copy the current row to the cache, or use "ayy copy," a as the buffer, and a can be replaced with any letter from a to z, you can complete multiple replication tasks.
Nyy // copy the N rows of the current row to the buffer. You can also use "anyy replication," A is the buffer, and a can also be replaced with any letter from A to Z, you can complete multiple replication tasks.
YW // copy the characters starting from the cursor to the end of the word.
Nyw // copy the N words starting from the cursor.

: % S/old/new/g // replace all old files in the current file with new

Edit Other resources:

: E otherfilename // edit the file named otherfilename.

Modify the file format:

: Set fileformat = UNIX // modify the file to Unix format. For example, ^ m will appear in the text file under Windows in Linux.

Objective answer

C parameters are passed by value. One function of a pointer is to achieve similar reference effects. In addition, you can use a pointer to directly operate the memory!

Sun he explained:

Each thread has a fixed stack size. Generally, the stack of the main thread is usually 8 MB by default, and the memory is referenced by pointers. The stack memory is usually used and the stack is limited, it is also affected by the lifetime. Therefore, there are more scenarios where the heap is used than the stack. Some things have a long lifetime. If more than one function is called, The heap memory is used.

The "tag list" plug-in is a source code browser plug-in compiled for VIM. It must be supported by ctags. You can list functions, global parameter lists, and macros on the left. (Sorted)

1. Download The taglist.zip file and decompress it to $ home /. in the vim directory, or in the $ home/vimfiles or $ Vim/vimfiles directory, after this step, you should have these two files (the directory structure should be retained)

Plugin/taglist. vim-taglist plug-in file
DOC/taglist.txt-document (HELP) File

2. Go to $ HOME/. vim/doc, $ HOME/vimfiles/doc, or $ VIM/vimfiles/doc.
Directory, run Vim, and run in command line mode ":Helptags. "Command to process the taglist help file. If you do not have this step, you will not be able to get the taglist help prompt

3. If the ctags tool is not in your PATH search PATH, you need to set the Tlist_Ctags_Cmd variable in $ HOME/. vimrc to indicate the ctags PATH.

4. If you are running VIM of the terminal/console version and terminal does not support changing the window width, you need to change the window width at $/HOME /. vimrc sets the variable 'tlist _ inc_winwidth' to 0,

5. Restart vim

6. You can use ":Tlisttoggle"To open/close the taglist window, you can use ":Help taglist"Command to get more information about using the taglist plug-in

Remove highlight

Method 1: nohlsearch
Method 2:/awertgvcxz (find a string that certainly does not exist)
After the highlighted search (: set hlsearch) is set, you can disable the highlighted search permanently through: set nohlsearch.
Display. You can also temporarily disable the highlighted feature by using nohlsearch. The highlighted feature is automatically restored during the next search. From: http://9esuluciano.javaeye.com/blog/137333
