How can I add space between operands and operator in emacs?

How can I add space between operands and operator in emacs?

[Zhou Lei]

Hi friends, how can I add a space between operands and operator, like this: from
"a=c+++3;" to "a = c++ + 3;"? I use GNU Indent for C code, but GNU Indent cannot
deal with something for C++. What should I do? Thanks.

M-% +++ ret ++ + ret !

Since addition is a commutative operation you could have written a = 3 +
c++;
What is the operator precedence of inc and binary +?

Here's an example of something even more perverse:

char*f="char*f=%c%s%c;main()
     {printf(f,34,f,34,10);}%c";
     main(){printf(f,34,f,34,10);}


or, more on topic:

((lambda (x)
       (list x (list (quote quote) x)))
      (quote
         (lambda (x)
           (list x (list (quote quote) x)))))

Both programs print themselves and were called quines by Douglas
Hofstadter, after the logician:

Ok, I'd better use M-| astyle to do that rather than using emacs...  Thanks for
your explanation.
