Question

Can someone explain the output of this pseudocode code to me?

Also S(n) is set_x() and P() is print_x()

I will rate!

sider the following pseudo code:
x : integer : =1
y: integer : =2
procedure set_x(n: integer)
X:=n
procedure print_x ( )
write_integer (x)
procedure add
x :=x+y
procedure fun(A: function; n: integer)
y: integer : = 3
if y>n
else
add ()
procedure foo(S, P: function; n: integer)
x : integer := 5
if n in {1,3}
else
A()
else
set_x(n)
S(n)
if n in {1, 2}
print_x()
P()
fun(add, n)
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
a. what will the program print if the language uses static scoping
b. if the language uses dynamic scoping, what will the program
shallow binding?
c. if the language uses dynamic scoping, what will the program
binding?
