Question

I am having a hard time understanding the output of this program with shadow and deep binding.

Can someone explain it more in detail? I posted the answers below

 

x : integer – – global
procedure set x(n : integer)
x := n
procedure print x()
write integer(x)
procedure foo(S, P : function; n : integer)
x : integer := 5
if n in {1, 3}
set x(n)
else
S(n)
174 Chapter 3 Names, Scopes, and Bindings
if n in {1, 2}
print x()
else
P
set x(0); foo(set x, print x, 1); print x()
set x(0); foo(set x, print x, 2); print x()
set x(0); foo(set x, print x, 3); print x()
set x(0); foo(set x, print x, 4); print x()

 

Here are the answers to the questions.
