I wrote what I've enclosed in <quote>s below in my email client, and then tried to send it, and found out that I can't post from my email client, I have to come here to post. So, the problem of getting posts as emails is solved, but I guess I have to come to google to post. I may look into Usenet unless someone can recommend a real "mail list" for a C++ newbie. (A mail list suits me much better than a forum or IRC.)

I might post more details later, but I have the problem resolved for myself (I
don't fully understand why it is this way, and this first attempt at an
explanation of what I did may not be as clear as it could be):
There are two places where you can choose how email updates are sent -- one is
on the main page of the list you are viewing (e.g., comp.lang.c++) and the
other is on the list of all the groups I am subscribed to ("my groups",
accessed from what is apparently the googlegroups home page).
On the comp.lang.c++ page, you get to make the choice by clicking on the down
arrow next to (or part of) the icon that is a human torso (help text is "My
settings") and then choosing "Membership and email settings". This is the
place where I only got the three choices for comp.lang.c++ (not including
"Every new message"), but, for the other groups I belong to, I get the "Every
new message" choice.
On the "my groups" page, all 4 choices appear, although on some groups (e.g.,
"Announcements and Alerts" it seems I can't choose among all of them (even
though none of them appear to be grayed out). Update: I lied -- the choices I can't make are gray (instead of black) -- I didn't notice that the first time I looked.
Aside on Usenet newsgroups: It is helpful to know that some Google groups (like this one) are actually Usenet newsgroups, but I don't think I have the need to
subscribe to a Usenet newsgroup server as long as I can read, post, and reply
to such newsgroups via Googlegroups.
