Study the following program written in a block-structured language:
Var x, y:interger;
procedure P(n:interger);
begin
x:=(n+2)/(n-3);
end;
procedure Q
Var x, y:interger;
begin
x:=3;
y:=4;
P(y);
Write(x) __(1)
end;
begin
x:=7;
y:=8;
Q;
Write(x); __(2)
end.
What will be printed by the write statements marked $(1)$ and $(2)$ in the program if the variables are statically scoped?
- $3, 6$
- $6, 7$
- $3, 7$
- None of the above.
