Vim settings for displaying row numbers, syntax highlighting, and automatic indentation

In ubuntu, the vim configuration file is stored in the/etc/Vim directory. The configuration file name is vimrc.

In fedora, the vim configuration file is stored in the/etc directory. The configuration file name is vimrc.

Enter the following command on the terminal to edit the vimrc configuration file:
Sudo Vim/etc/Vim/vimrc
Or sudo gedit/etc/Vim/vimrc

1. display the row number

Add a new line at the end of the file and enter SET nu

2. syntax highlighting
Find "syntax on" in the file and remove the double quotation marks. Double quotation marks indicate the meaning of the comment.

3. Automatic indent

Add a row at the end of the file and enter SET autoindent.
After adding a row, enter SET cindent
Autoindent indicates automatic indent, and cindent indicates automatic indent for C language syntax.

NOTE: If Vim does not take any action after the preceding settings are configured, upgrade Vim to the latest version. Generally, you only need to enter the following command on the terminal: sudo apt-Get install Vim

Have a good time using vim!

Next we will show you how to learn C in Linux. C in Linux, the compiler is GCC. You can use Vim on the terminal to input the source code of C.

Save it to hello. C and run it on the command line:

# GCC hello. C-O hello

In this case, an executable Hello file is generated and entered in the command line:

#./Hello

You can run the C source code you just compiled.

C ++ can also be compiled in Linux, and the C ++ compiler in Linux is g ++. Note:

The header file of C ++ is iostream rather than iostream. H. You also need to add the namespace STD, for example:

// Hello. cpp

# Include <iostream>

Using namespace STD;

Int main ()

{

Cout <"helloworld! "<Endl;

}

In this way, the compilation can be normal. In this directory, the terminal inputs:

# G ++ hello. cpp-O hello

In this way, a hello executable file is generated, and the./Hello command is used to run it.
