Even better, perhaps:

(add-hook 'find-file-hook
          (lambda ()
            (when (string-match "\\.cpp\\'" buffer-file-name)
              (set (make-local-variable 'compile-command)
                   (format "g++ %s"
                           (file-name-nondirectory buffer-file-name))))))
