declare variable in switch?

Why can't variables be declared in a switch statement?

switch (i){
 case 'i': int i; break; } //it works


switch (i){
 case 'i': int i;i=0; break; } //it also works


switch (i){
 case 'i': int i=0; break; } //it ain't

That code you presented will work just fine. Have you tried it? — Johannes Schaub - litb, Jan 16 '11 at 13:28

Dunno the error, but this also works for me in Objective-C (strict superset of C, although I don't believe that ¹) and I do this always, even when I simply return something:

switch (i) {

  case 'i': { // <- curly brackets
    int i = 0; break;
  } // <- curly brackets

}

^{(1 Because a variable can be named id in C but not in Objective-C)}

True. I always use Clang which always defaults to C99 so I'm used to it. – Jan 16 '11 at 13:16
