yes common lisp uses GC.

what about C ?

" The Boehm-Demers-Weiser conservative garbage collector can be used as
a garbage collecting replacement for C malloc or C++ new. It allows you
to allocate memory basically as you normally would, without explicitly
deallocating memory that is no longer useful. The collector
automatically recycles memory when it determines that it can no longer
be otherwise accessed. A simple example of such a use is given here."

you must be a newbie.

Hmmm.

Seriously, my once a month statement is to read Baker:

"Henry Givens Baker Jr. is an American computer scientist who has made
contributions in garbage collection, functional programming languages,
and linear logic. He was one of the founders of Symbolics, a company
that designed and manufactured a line of Lisp machines. In 2006, he was
recognized as an ACM Distinguished Member."

He is notable for his research in garbage collection, particularly
Baker's real-time copying collector, and on the Actor model.

Baker received his B.Sc. (1969), S.M. (1973), E.E. (1973), and Ph.D.
(1978) degrees at M.I.T.
"

just google for 
Henry baker +lisp +GC

 .

When I program in C I do not use GC, I use exit.
