troubles about using goto statements

[winter1970]

my CVI is CVI2013.

in a function called Send(),which is defined myself,i used goto statements to jump out of switch statements inside of for statements.

which is showed below:

int Send()

{

       for(...) //the first for

       {

             if()//the first if

            {

                   for()//the second for

                  {

                        switch()

                         {

                                  case 1:

                                  goto         Label1;

                           }//end of switch

                   }//end of the second for

             }//end of the first if

   Label1:  continue;    

     }//end of the first for

}

when i compiled it ,it showes:

" 485, 49 error: use of undeclared label 'Label1'",

"624, 1 error: use of undeclared identifier 'Label1'"

why?

With the risk of being simplistic, I would double check that a true colon is used after the label definition and not a semicolon: it's something that sometimes happens to me, they are so similar!

in my function, there is not only one "goto Label1",may be the reason of coming faults?

int Send()

{

       for(...) //the first for

       {

             if()//the first if

            {

                   for()//the second for

                  {

                        switch()

                         {

                                  case 1:

                                  goto         Label1;    ///    Number1

                                  break;

                                 case 2:

                                 ....

                                 goto      Label1;       /// Number2

                           }//end of switch

                   }//end of the second for

                  goto   Label1;         ///Number3

             }//end of the first if

   Label1:  continue;    

     }//end of the first for

}

similarly above, only defined one Lable "Label1", but have some calling"goto Lable1". Maybe it is the reason?

[RobertoBozzolo]

You may have as many goto statements as you want, that's not the problem.

But that "undeclared identifier" error on line 624 probably points exactly to Label1: line which in my hypothesis is not correctly written (e.g. the colon is missing or is replaced by a semicolon)

[ebalci]

Why don't you simply write continue instead of goto Label1.
goto's are not the best coding practice.

Can you copy and paste the exact code?  There may be something wrong in the code that's not showing up in the snippets you've posted so far.

last time,when i met the troubles when using "goto",i used flags instead of 'goto',and it works.

today,when i see your replys,i used "goto" to recode the source, and now the troubles never appeared.

so, it seems to be very confused me.

maybe, some wrong syntax caused it.

i use tortoiseSVN to record my project,and i forgot to save last "goto" codes last time ,and now it cannot to be reappeared.

thans all.
