func()
{
     code;
     more code;
     int foo;
     even more code using foo;
     even even more code not using foo;
}

What is the scope of foo end?

now compare:

func()
{
     code;
     more code;
     {
        int foo;
        even more code using foo;
     }
     even even more code not using foo;
}
