Sudo Vim/etc/Vim/vimrc
Or sudo gedit/etc/Vim/vimrc

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

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.
