Programming peeve of the Day

if (condition)
{
return;
}

// Do something else

what about this annoys you?

Forogar

Obviously it should have been:

if (!condition)
{
// Do something else
}
else
{
return;
}

Your rewrite is how it should be done. Now get off my lawn.

cheers Chris Maunder

...erm, your code is not the same logic. You have inverted it.

I would never do it the same, but I can understand it as a hint and that is ok. Of course

if (condition) return;
// Do otherwhise

would be more appropriate On the other hand: Is it really worth to discuss such little things?

You're absolutely correct. Let's discuss this, instead: if (condition) { return; } else { // Do something else }

Ah ok I see you have a problem with 'if ... else' ;P [Edit] Is see in your profile "In real life, a research chemist." Yep, better stop programming. This because programming follow strict rules while chemistry has only exceptions ;P

Is snot.

if ( !condition )
{
// Do something else
}

return ;

Why? It's not as clear as to what the code will do. Plus, returning from inside an if is bad form.

when you refactor some code and are too afraid to remove else clauses.

I like single exit points... That code would drive me nuts too...

What's wrong with returning from inside an if? The rule about only returning at the end of a function leads to convoluted code where a flag is repeatedly used to bypass stuff just to reach the end of the function. Pure dross.

I believe to be totally proper it should be;

if ( !condition )
{
// Do something else
return;
}

return ;

As opposed to it not being clear when and where something can be returned.
