Find the value of Z

Question

P(X:integer,Y:integer) {
    X = 6;
    A = 8;
    return ( X + Y )
}

if the function P were invoked by the following program fragment.
 

k = 1;
L = 1;

Z = (K, L);

Then the value of Z would be?

where X=call by reference and Y=pass by value

Answer 1

Since k is passed by ref so k and x will be pointing to same memory loc.while y which is passed by value has value of l . Y= 1.

Now in p function, x or k = 6. And y remains same . Y= 1.

Therefore z = (6 + 1) = 7
