I agree entirely with this. It's pretty much what I do. I try to slurp
in the data, sanity check it, and then place it into an area that might
be best described as a 'known good' area. For example, when I implement
a list, I sanity check the input when it's provided to be placed in the
list. If the proper interfaces are used, there is never again a need to
make sure that your pointers aren't NULL and your strings are
terminated. I do provide, for the truly paranoid, a function which
iterates through the list and sanity checks all the contents; but I
never use it.

I can see several points in the C++ language that make it attractive for
large projects with deadlines... like commercial applications. If the
programmer will not maintain it, it carries several other niceties.
However, all the benefits of C++ seem to be social, rather than
technical; likewise the benefits of OOP. OOP is really great if you have
five teams in different countries working on a project. It's a fantastic
tool for DoD work, as well. But in most computing... I don't see much of
the benefit.
I will admit that heavy Windows programming is almost required to be in
C++, much as the SDK in Windows 3.0 more or less required that you work
in C. But Delphi's got some real potential, although I hate to admit
that any Pascal derivative is anything other than garbage, and Visual
Basic is a wonderful rapid prototyping language. It also makes good blue
glue.

Just as there aren't a lot of C compilers left that translate into
assembler. ;)
Language evolves...
