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. # (Use commands in normal mode) search for and jump to the word where the cursor is located. 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.

D (used in the taglist window) deletes files from the list. + (Used in the taglist window) Expand the file. -(Used in the taglist window) collapse the file. = (Used in the taglist window) collapse all files. X (used in the taglist window) shows or hides the normal window.

File ListNERD_tree.vim (plug-in) Horizontal Split Window (multi-row window ). Let NERDTreeWinPos = 'right' (written to the configuration file. vimrc). If you want to display the file tree on the right, add this configuration. The default value is left. : NERDTree (use commands in normal mode) to display the file list.

Other vim commands (refer to vi (vim) Tutorial)

Open, save, and close a file:

Vi filename // open the filename file w // save the file w vpser.net // save it to the vpser.net file q // exit the editor. If the file has been modified, run the following command: q! // Exit the editor without saving: wq // exit the editor and save the file

Insert text or line:

A // Add text I to the right of the current cursor position // Add text A to the left of the current cursor position // Add text I to the end of the current row // add text at the beginning (first line of non-null characters) O // create a new row on top of the current Row o // create a new row under the current row R // Replace (overwrite) the current cursor position and several subsequent texts J // merge the row where the cursor is located and the next row as a line (still in command mode)

Move the cursor:

Use up, down, left, and right direction keys

Command mode: h to left, j down, k up, l to the right. Space key to the right, Backspace to the left, Enter to the next line first,-to move to the previous line first.

Delete:

X // Delete the current character nx // Delete the n-character dd starting from the cursor // Delete the ndd of the current row // Delete the n rows including the current Row u // cancel the previous operation U // undo all operations on the current row

Search:

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

Jump:

N + // jump n rows n-// jump n rows nG // jump to n rows G // jump to the bottom of the file

Set row number:

: Set nu // display 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. Y ^ // copy the content from the cursor to the beginning of the line.

Y $ // copy the content from the cursor to the end of the row. P // paste the content in the clipboard after the cursor. If the preceding custom buffer is used, we recommend that you use "ap" for pasting. P // paste the content in the clipboard before the cursor. If you use the custom buffer above, we recommend that you use "aP for pasting.

Replace:

: S/old/new // replace the old: s/old/new/g that appears for the first time in the row with new // replace all old: n in the row with new, m s/old/new/g // use new to replace all the old values in the n to m rows: % 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.
