A Label Can Only Be Part Of A Statement And A Declaration Is Not A Statement Struct

takes a minute: Sign up Why do I get “a label can only be part of a statement and a declaration is not a statement” if I have a variable that is initialized after a label?

C Declare Variable In Switch Case

the following simplified code: #include int main () { printf("Hello "); goto Cleanup; Cleanup: char *str = "World\n"; printf("%s\n", str); } I get an error because a new variable is declared after the label. If I put the content (mainly initialization) after the label in a {} block, compilation succeeds. I think I understand the reason for the block in case of a switch, but why should it be applicable in case of a label ?

Got one that's confusing to me. I'm running XIDE v2.05, with XC16 v1.21 on a PIC24F16KL402 target. Compiler optimization is set to 1.Ths issue is, with a switch:case statement. And depending a label on where I declare variables, I get errors.Consider this code fragramentswitch (InCmd) {case 'b':int Num = 1;InCmd = InCmd;:which compiles with the following errors:../Test-002.c:715:13: error: a label can only be part of a statement and a declaration is not a statementHowever if I do the following in code:switch (InCmd) {case 'b':InCmd = InCmd;int Num = 1;everything compiles without errors.Long story short is immediately after a case statement, a variable cannot be defined. a label can Any time this happens an error occurs. However, If I do anything in code that is not defining a variable (calling a function, doing math on existing variables, etc.) the code compiles just fine.Any ideas what's gong on here?Thanks,Dan #1 10 Replies Related Threads Chris A Super Member Total Posts : 684 Reward points : 0 Joined: 2010/07/20 04:37:07Location: 0 Status: offline Re: Switch Statement. 2014/05/09 07:34:49 (permalink) 0 Nether should compile. This is 'C' not C++ and that only allows you to define a variable in a function at the start of a block unless i'm out of touch :-(You can always add {... } after the case if you want to make Num local to that case. #2 malaugh Super Member Total Posts : 135 Reward points : 0 Joined: 2011/03/31 14:04:42Location: San Diego Status: offline Re: Switch Statement. 2014/05/09 07:54:16 (permalink) 0 Chris is right. They are both wrong and neither should compile. the correct version isint Num;switch (InCmd) {case 'b': Num = 1;InCmd = InCmd; post edited by malaugh - 2014/05/09 07:55:49 #3 dkemppai Starting Member Total Posts : 75 Reward points : 0 Joined: 2012/04/30 11:23:04Location: 0 Status: offline Re: Switch Statement. 2014/05/09 08:01:16 (permalink) 0 Chris,Your response was a bit of a surprise to me.
