Question 49
|
Program PARAM (input, output);
var m, n : integer;
procedure P (var, x, y : integer);
var m : integer;
begin
m : = 1;
x : = y + 1
end;
procedure Q (x:integer; vary : integer);
begin
x:=y+1;
end;
begin
m:=0; P(m,m); write (m);
n:=0; Q(n*1,n); write (n)
end
The value of m, output by the program PARAM is:
|
1, because m is a local variable in P
|
|
|
0, because m is the actual parameter that corresponds to the formal parameter in p
|
|
|
0, because both x and y are just reference to m, and y has the value 0
|
|
|
1, because both x and y are just references to m which gets modified in procedure P
|
|
|
none of the above
|
Question 49 Explanation:
0, because global m is not modified, m is just passed to formal argument of P.
Correct Answer: B
Question 49 Explanation:
0, because global m is not modified, m is just passed to formal argument of P.
