Mark the region and hit M-;. Hitting M-; again removes the comment
lines again. I think you need to turn on transient-mark-mode for this
to work.
Perhaps C mode also supports the C-c C-c binding to comment a region
of code. Use C-u C-c C-c to uncomment.

There are M-/ and C-M-/. I think that M-/ is somewhat similar to
Ctrl-P, but it searches in both directions and it searches other
buffers, too. C-M-/ provides completion, whereas M-/ cycles through
the list of possibilities.
