Yes, this is standard C. The current C standard is C99.
Unfortunately, the current standard is not (yet?) as widely supported
as the previous one, C90. Mixing declarations and statements can
still cause portability problems if you care about platforms that
don't have C99 compilers (or at least C90 compilers that support
mixing declarations and statements as an extension).

We must do something. This is something. Therefore, we must do this.

I know Keith, but you will
NOT
have any of those problems using lcc-win32 !!! (

I care about standards and implemented that quite a
while ago.

Fair enough. Still a risky habit to get into, if one ever uses a
different compiler.

Yes, jacob, we know that.

I do have one major problem with lcc-win32: it only works in a single
environment. Others may find it useful in spite of that. I don't.

Great, but in the real world many of us still have to deal with
pre-C99 implementations, and it would be foolish to ignore that fact.

Fortunately that particular C99 feature, though it's nice to have, is
not essential. It's easy enough to restructure your code so that all
the declarations precede all the statements in each block. The
resulting code (assuming no other problems) is legal in both C90 and
C99.

Thanks for the complete re-editing of my original program.
You're right: I must learn to use more functions in programming and
master many other techniques. But you know, programming isn't only a
science is mainly an art to be learnt step by step from other artists!
Thank you indeed
