Well,

to set the maximum number of characters per line with auto-fill-mode
is:
    C-u nn C-x f

were "nn" is the number of characters, i.e. 70 in your case. But
observe that:

 1. This requires auto-fill-mode to be on (a minor mode toggled on/off
    with M-x auto-fill-mode)

 2. auto-fill-mode is a mode intended for *text*, I *think* it will
    only be a nuisance in a programming mode like C++.

Read about 'set-fill-column' function. This is probabely what you
want.

I cannot tell you how but as almost anything in Emacs is tweakable it
would certainly be possible to hook-on a function that after each
keyboard press checked if the current column was greater then a
certain number, and if it was, BEEP at the user. Would be very
annoying though... :)

(defun annoy ()
   (if (>= (current-column) 70)
       (beep t)))

(add-hook 'post-command-hook 'annoy)
