Depending on the context you want it, you can either read the output
of the command into the current buffer with

:r !g++ --version

or you can put it in a variable to be manipulated:

:let my_var=system('g++ --version')

Note that this will give you the complete output, so you'd have to
throw away the bits you don't want.
