There are a couple of ways to deal with this:
1. Replace this:
int i = 0;
with this:
int i;
i = 0;
2. Put some more of these { } in the code.
That is, replace this:
goto there;
// ...
int i = 0;
// ...
there:
With this:
goto there;
// ...
{
int i = 0;
// ...
}
// ...
there:
In general, classes with constructors MUST be initialized,
so the general rule is good. With the work arounds above,
it is not hard to obey the rule for simple variables.
