Thread: Replacing switch statements?

Hello all, i have a sort of silly question to ask.
My question is:
"What would be the best way to replace switch statements without using if?"

Also, is there a way to break out of a multiple level nested conditional operator being used as an lvalue-less statement?

Code:

int a,b,c;  /* Just exemplary variables */
a ? (b ? (c ? 1:0) : XXX ):0;   /*  Expression used for it's sideeffects */

At the point where i assign the value XXX i want to break, or goto (if possible)
The actual expression is much more complex, and would obfuscate things if i pasted it.
It is forbidden to use 'if' or 'switch' as a solution.

It is not for an assignment, i was just curious and thought it would make interesting code since then one could replace an entire switch in one and only statement.
Thanks in advance for any try on this.

Why do you want to do this?

Do not use nested conditional operators.

That is silly as it leads to code obfuscation.

Actually i am writing some obfuscated code, and the switch statements are too obvious. I just thought i could do away with conditional operators managing the entire switch, but then again i could not control execution within conditional operators. Maybe i should use a function or something. I don't know if i can 'goto' from one function body to the other using just plain 'C', although i imagine that would be very bad for the stack frame

Hm. I seem to recall replacing a nested switch in this. I think I used an FSM.

Thanks Dave_Sinkula! That was very helpful indeed!

Come to think of it -- or rather, digging it up -- it was actually nested loops.

Well, a function table can replace a switch. Just fill an array with function pointers with the appropriate array number.
