GRE Computer Science Question 13
13. Consider the following pseudocode.
program main ()
begin
integer a, b, c, i
a = 6
b = 7
c = 8
i = fun(a, b, c)
print i, a, b, c
end
integer fun (integer x, integer y, integer z)
begin
if (x greater than 6) then
y = 25
z = x + y
return y + z
end
If fun uses call-by-reference, what values would be printed as a result of executing the pseudocode?
i a b c
(A) 6 20 8 7
(B) 6 20 13 7
(C) 20 6 7 8
(D) 20 6 7 13
(E) 56 6 25 31
