C-c C-q will reindent the current function.

C-M-q will reindent the contents of a "sexp".  (i.e., put point on an
opening brace, and C-M-q will reindent the innards.)

C-M-\ will reindent the current region.  (The "region" is the bit of text
between "point" (the cursor) and the "mark" (where you last typed
C-<space> or started a search, or .......   To find where the mark
currently is, type C-x C-x.  Then type C-x C-x again to get back.  Lots
of things set the mark in Emacs.)

Hint:  In a C++ buffer, type C-h m.  This will give you a list of
C++-specific commands.  Wherever you see ESC <something> you can type
M-<something> instead.
