Variable declaration after goto Label

Question

Today I found one interesting thing. I didn\'t know that one can\'t declare a variable after a goto label.

Compiling the following code

#include <         


        

Answer 1

You want a semi-colon after the label like this:

 #include 
 int main() {
     int x = 5;
     goto JUMP;
     printf("x is : %d\n",x);
 JUMP: ;     /// semicolon for empty statement
     int a = 0; 
     printf("%d",a);
 }    

Then your code compiles correctly for the C99 standard, with gcc -Wall -std=c99 -c krishna.c (I'm using GCC 4.6 on Debian/Sid/AMD64).
