two questions

[Frank]

1)
Is there any free software that can pretty up my C code.

2)
I remember years ago something different happens if the extension on the
code file is .c rather than .cpp.
Is that still the case and if so what is the difference.


Thanks in advance

Today is still valid...

..c files are compiled like C source files (unless you use /TP compiler flag)
..cpp are compiled like C++ source files (unless you use /TC compiler flag)

Isn't C a subset of C++??

Thanks a lot.

Not exactly. There are some incompatibilities between languages. With the last C
standard (C99) there are even more...

Take a look this

Very interesting site. I've wondered if he was still active.


Thanks

Very interesting site. I've wondered if he was still active.

Not only is he still active, he's working on the next set of upgrades to the
C++ standard, called C++0x, which will include most of the new things in C99
into the C++ standard. Most compilers already have the extra C99 stuff
already, as vendor extensions to C++.

The major remaining difference between C and C++, that won't go away, is
that C provides a lot of defaults (default int return value, default
prototype) whereas C++ forces the programmer to specify the correct
information.
