You’re editing a C source file and while you’re still in vim editor session and want to enable syntax highligting feature, just give the following command, pressing ESC before:

:syntax on

You can make this behaviour as default for your own future user session entering following lines in your ~/.vimrc file:

syntax on

You can even make this behaviour as a system wide default with entering above lines in /etc/vim/vimrc configuration file.
