C++ coding style and in-place operators

[rik]

All,

Do we have a preference for where in-place operators are used?  For
example, the following statement can be coded two ways.

a = a + 1;
a += 1;

In m-files there is a distinct preference for the in-place operator which
is faster as it doesn't allocate an intermediate variable.  In the C++
code, do we assume the compilers are smart enough these days to perform
that optimization?  And even if they are, do we like one style more than
the other?

Attached is a list in liboctave of opportunities to use in-place operators
that I quickly found using regular expressions.
