Because there are limits to the indention in emacs...
namely that it will not fix misplaced braces in C/C++

I.e. if you prefered style is K&R

if ( thing ) {
        ....
}

and the code is indented as

if ( thing )
{
        ...
}


(Or vice-versa).


I generally find that Gnu Indent with a suitably setup rc file
is very useful for doing this type of indenting / conversion.

(It is also a lot quicker to run it over large numbers
of files).

Perhaps it can be combined with the other suggestions of format.el
to do what you require.
