Absolutely, yes, I thought about that and just be done with it.
I wonder if that's the right compiler behavior though;
is it acceptable that the compiler cannot figure out that needle is always
initialized before use when you have
switch (format) {
case 'c':
needle = SOMETHING;
...
}
if (format != 'c') {
needle = SOMETHING_ELSE;
}
actually_use(needle);
?
Ciao,
