A well written program in a compiled language like C++ will
always execute much faster than a similar program written in
Mathematica code. But I strongly believe this type of comparison
isn't useful. The execution speed advantage of C++ is more than
offset by the development time for the program.

=46or any non-trivial program written in Mathematica code, you
will be making use of Mathematica function that would have to be
re-written in C++ code. And even if this is not the case, things
that take several lines of C++ code tend to take much fewer
lines of code in Mathematica. This is an inherent advantage of
using a higher level functions available in Mathematica and not
available in C++.
