If I might add (being somewhat experienced in C++):
C++ is an exteremely 'complicated' if you need efficiency. Whereas
C has a reasonably constant number of assemby instructions per
C instruction (I think it averages around 5), C++ has a greatly
varying number of assembler statements per C++ statement, it may
be more than 500! (If you consider for instance an 'elegant'
construction
with a derived class and such. The code becomes less transparent and
it is less easy to guess what impact a certain statement will have.
It is possible to write high performance apps like kernels and
emulators in C++, but if you are no expert in the language C++ with
all it's 'tricks', it will probably fail to perform well.
In C, this is more easy since you can see, just by counting lines,
how expensive your code is. (VERY roughly, of course, and this doesn't
mean that writing plex in C is easy, but just that you need to
be less of a wizard in C than in C++ to prevent performance problems).

In an age when employees are labeled 'human capital' and workplace
longevity
is measured in months, some companies have finally begun to realize that
a
truly loyal employee is a rare and valuable asset that should be
recognized,
nurtured, and, ideally, sold to the highest bidder.
