do you use goto? [modified]

Graham Bradshaw wrote:

Not explicitly, anyway. If you've ever used a C break or continue, implicitly you have, since break and continue are simply goto's with an implicit label that is just outside or inside the current end of scope.

By that reckoning anyone using an if ... then ... else is also using a goto. The argument is not that "jump" statements in a program are not required (in any non-trivial program they are unavoidable), but that structured programming constructs rather than the goto statment lead to more understandable programs. As Dijkstra said in his original letter[^] - "The go to statement as it stands is just too primitive, it is too much an invitation to make a mess of one's program." I haven't used a goto statement since I gave up programming in Basic

As in "go to h***" when I see someone using goto. Marc

Again, not really. I've encountered situations (even recently) where I felt that a few goto statements will save me from writing a buttload of ugly nested if-if-if statements.

Doesn't bother me at all to use goto. I haven't found a c++ compiler that doesn't support them. They're not evil, just one more programming construct. If it saves me 100 or 10 or even one line of code, I'll use a goto without thinking twice.

"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.
