See K&R2, page 50, or Deitel & Deitel (5th edition), page 85, or Harbison &
Steele (4th edition), page 223 - or if you have some other reference book,
simply look up += in your C book's index. If you don't have a C reference
book, get one - preferably one of the above, or "C Programming: A Modern
Approach" by K N King (which I don't actually have, but apparently it's
very good).

This is functionally equivalent to the three statements below:

i = i + 1;

i++;

++i;

Specifically, it is a shorthand notation for the first one. Others are:

x /= y; (for x = x / y
x -= y; (for x = x - y
x *= y; (for x = x * y
x %= y; (for x = x % y
x >>= y; (for x = x >> y
x <<= y; (for x = x << y
x &= y; (for x = x & y
x |= y; (for x = x | y
x ^= y; (for x = x ^ y

These shorthand operators are called as assignment operators.
Look them up in your textbook or reference.

yes they are very good

Yes, you are right. I should have said "effectively" instead
of "functionally", and qualified that it was only for the particular
case presented by the OP.

Meaningless.

If you want to post a followup via groups.google.com, ensure
you quote enough for the article to make sense. Google is only
an interface to Usenet; it's not Usenet itself. Don't assume
your readers can, or ever will, see any previous articles.
