Better: bind this function only in c-mode and c++-mode. No test needed
in the command itself.

  C-h v c++-mode-map RET
  C-h v c-mode-map RET

and C-h f looking-at RET. You don't even need to get it in a string.

(if (save-excursion
      (beginning-of-line)
      (looking-at ".*return;")) ; adapt ...
  ...
...)

C-h i m eli TAB RET ;-).
