Problem 1 (2.5 points) (Scopes and Binding). Consider the following pseudocode, assuming nested subroutines and static scope. procedure main g : integer; procedure B(c : integer) x : integer; procedure A(n : integer) g := n; procedure R(m : integer) write integer(x); x := x/2; –– integer division if x > 1 then R(m + 1) else A(m); –– body of B x := c + 4; R(1); –– body of main B(3); write integer(g); (a) What does this program print? (b) Show the frames on the stack when A has just been called. For each frame, show the static and dynamic links. (c) Explain how A finds g.
