"Switch" is just "on x GOTO" so, yeah, all the time.

Wouldn't evaluating an expression upfront to a variable and then using a switch-case provide an elegant in that case?

The only time I've ever used goto was in the QBasic days, and in Visual Basic when I was first learning that language. I've never used it in any C flavor language, and never allow it when doing code reviews at work.

1. switch works only with integral types and so it cannot be used everywhere. 2. switch uses goto internally.

under any circumstance use goto I use the following

#define BeamMeUp(_goto) goto _goto

int AtPlanet()
{
bool bToDangerous = true;

if(bToDangerous)
  BeamMeUp(scotty);
else
  Fight();

scotty:
  return ToEnterprise();

}

Goto's are evil and real programmers never use them.

I use label: … goto label whenever I have to use while (true) { … }

So the creationist says: Everything must have a designer. God designed everything. I say: Why is God the only exception? Why not make the "designs" (like man) exceptions and make God a creation of man?

To learn recursion you first need to know recursion!

Thanks allot leppie :mad: now i'm forced to make jumps :laugh:

I have less than 5 gotos in the 500K+ lines of code I have written in the last 10 years so its quite rare for me.

No, but I reserve the right to use it and not feel bad.

if uses goto internally. while uses goto internally. for uses goto internally. function calls use goto internally. Your CPU only knows goto internally. There's a reason why modern programming languages provide a collection of wrappers to hide goto from you.

I haven't used a goto in 25 years of programming, but I like the option to be available in case I need it. It's been claimed that a goto is useful for exiting deeply-nested code when an error is detected. But in the evolution of my programming style, my methods have become much shorter and only rarely have deep nesting. I can only think of two occasions a goto was necessary. One was when I encountered a bug in IBM's PL/I compiler back in the 1980s, and I needed a goto to force sequential execution. (The next statement wasn't being executed.) The other time was in grad school in the 1990s when I was implementing a system that translated a flow graph drawn on the screen into C code. Each mechanism (a box on the screen representing a library component) was assigned a label, and gotos were part of the automatically-generated template for sequencing their execution. A goto would also be useful for a rapid fix under time pressure. It's good that gotos are discouraged. They're easy and the temptation to use them is great for that reason. (I used them constantly in BASIC when I first learned to program.) But code is already complex enough without making it more complex with abrupt changes in flow.
