Given the following:

procedure Main is

X:Integer;

procedure Sub1 is

begin -- of sub1

Put(x);

end; -- of Sub1

procedure Sub2 is

X: Integer;

begin -- of Sub2

X:= 10;

Sub1

end; -- of Sub2

begin of Main

X:= 5;

Sub2

End; -- of Main

1. Assume static scoping. What value of x is printed in procedure Sub1?

b. Now repeat assuming dynamic scoping
