function?

I've been tasked with implementing a feature check in some existing
code and I wondered if this could be done:

function HorribleCode()
{
TypeCheck(); // if GoodCode_Data is returned, "end" HorribleCode
()
return HorribleCode_Data;
}
function TypeCheck()
{
if (HorribleCode_Data == 'bad')
{
return GoodCode_Data;
}
}

Is this possible without implementing an if-else within
HorribleCode()?

For the, "Why would you want to do this?" crowd, I don't per se,
I'm just curious if it can be done and if so, how?

Thanks for your help!

Hi,

Maybe have a look at try/catch.
Make sure an exception/error occurs when the check fails.
Maybe throw it yourself:
throw new Exception("Horriblecode found a problem");

When you don't catch the exception, all was fine.

exceptions are costly - you should not use them for something like
invalid user input, but just in cases something really went wrong, for
example, when database connection fails.

Certainly, the right way to do it is by returning an appropriate value
(or returning and setting and setting a pass-by-reference parameter).
You can have multiple return statements in a function.
