Netbeans (and probably most other IDEs) will.

I have used Netbeans to format C/C++ code.  It has a wide variety of
custom settings.  The Netbeans ANSI style/format (with a few custom
settings) produces source code which is very close to the way I write
code. There are also options for Linux and GNU styles.

Netbeans also has a GCC/GDB interface for writing and debugging C/C++
apps.  It is usable, but I mostly use it only for Java, and for source
code formatting.

If you go to the add-ons, there is a C module.  Once it is
loaded the functionality is included.

Netbeans 7.x and later are all I've used, but they've all
had it.

You can also directly download the C/C++ version:
https://netbeans.org/downloads/

63MB on Windows.  62MB on Linux.

   It's not online,  but I would recommand emacs. You  press [Alt]-x &
tap indent-buffer. You can also bind  a key to that command, but since
it's not  really used, I  would not. You  may set different  styles of
indentation. K&R, GNU, etc. You can also indent a region.

   For  an  online  tools, I  don't  really  know  for  C. I  went  on
prettyprinter.de  & it  does  the job.  Not perfect,  but  a search  &
replace removes unnecessary spaces.

(not available in my Emacs -- indent-region, yes, but not indent-buffer)

But I don't think this does what the OP wants.  Emacs indents line by
line, so if the line breaks are gone, or you've got odd lines already
(such as if (x) y = x; else x = y; all on one line) it won't split the
statement and indent the result.  The commonly used indent command has
the same restriction.

That requirement got snipped so it's easy to have missed it.  I wonder
if the suggestion to use NetBeans has the same flaw.

   Sorry, you're totally right. I took that function from a portion of
preclude.

   You're right again.  There are a lot of tweaks  in my config files.
There's  gnu indent.  It's pretty  powerful,  but that's  not part  of
emacs.

   Again sorry. I've  edited my config file some time  ago, so I don't
remember all what I did.

That's an understandable goal, but the tools I've used that had anything
close to that ability, didn't go quite that far. The tool I'm most
familiar with is GNU indent: it will insert line breaks where required
by the style rules that it is applying, including maximum line lengths,
and will remove line breaks that are prohibited by that style, and will
break up overly long lines - but it will not merge short lines. Without
such mergers, the normalization you're hoping to achieve won't happen.
Personally, I don't mind, because I sometimes insert more newlines than
be explained by any hard-and-fast style rule, in order to emphasize some
aspect of the structure of my statements that isn't covered by any of
those rules.

Hmm – does that mean discarding all comments?

Will you also want to detect variations of sequencing e.g.

    int a, b;
    int a; int b;
    int b; int a;
    int b, a;

and similar?

Note: the standard considers comments to be white space, rather than
tokens, so two files can have the same sequence of tokens even if they
are commented differently. Therefore, you'll need to make appropriate
changes to your description of the desired behavior.

Consider:

int main(void) /\
* comment *\
/
/\
/ comment\
  comment
{
}

but maybe you deal with joined lines at another layer of processing.
