[請益] call by value, call ref, call by name
有一題問call by value, call by ref, call by name的值
我試寫了，想問高手我的答案是正確的嗎？
function confuse(x,y,z)
{
x=x+2;
z=z+y;
printf(x,y,z);
}
main()
{
x=1;
y=2;
z=3;
confuse(x,x+y,z);
printf(x,y,z);
}
call by value，我的答案是(3,3,6)
(1,2,3)
call by ref, 我的答案是(3,3,6)
(3,3,6)
call by name,我的答案是(3,3,6)
(3,3,6)
不知道對不對？
另外題目有問到這個程式語言的scope？這什麼意思？
