Statement goto can not cross variable definition?

Question

Suppose these code compiled in g++:

#include 

int main() {
    int a =0;

    goto exit;

    int *b = NULL;

exit:
    return          


        

Answer 1

There is an easy work-around for those primitive types like int:

 // ---  original form, subject to cross initialization error.  ---
 // int foo = 0;

 // ---  work-around form: no more cross initialization error.  ---
 int foo;  foo = 0;
