what will happen if we print the following...

[Shraddha]

for( ; ; );
printf("Hi");

 

[=?iso-8859-1?q?Erik_Wikstr=F6m?=]

for( ; ; );
printf("Hi");

If you can't figure this one out you really should study your book a
bit closer.

 

[James Kanze]

for( ; ; );
printf("Hi");

It does nothing, and tekes forever to do it.

In many shops, putting a semicolon on the same line, after the
for, will also get you fired. If you want to write an empty
loop, at least put the empty statement on the following line,
either:

for ( /* ... */ )
;

or

for ( /* ... */ ) {
}

(or whatever bracing style the local conventions calls for).

Even better is:

for ( /* ... */ )
/* do nothing */ ;

/* do nothing */ ;

If the company accepts loops without braces. I use:

for ( /* ... */ ) {
}

But all my control statements use braces, always. And while an
empty set of braces is fairly visible, you're right that a
single ';' doesn't show up very well, and something more doesn't
hurt.
