One idea is to type M-i instead of TAB.  (Mnemonic: TAB is C-i.)  M-i
advances to the next tab stop.  Tab stops are defined in
tab-stop-list -- use C-h v tab-stop-list RET for more information.

Another idea is to use align.el.  Mark these three lines and type M-x
align RET.  Or perhaps M-x align-regexp RET = RET.

This is somewhat complicated.  The variable c-basic-offset controls
how many columns does Emacs indent in such a case.  The variable
indent-tabs-mode controls whether Emacs uses tab characters (plus
spaces) to move to that column, or just space characters.  The
variable tab-width controls how wide a tab character is.

Actually, c-basic-offset is a simplification.  See the key combination
C-c C-o for more information.  (C-h k C-c C-o or try it.)

All of them need to be set up correctly for your environment.  In the
above example, c-basic-offset needs to be 4, indent-tabs-mode needs to
be t, and tab-width needs to be 4.  Then the "int res=0;" line will be
indented with a single tab character.
