For the following code, show the output for the 5 output statements (#1..#5) under the parameter passing methods stated.

Assume static scoping

PROGRAM EX1;

int i; // global

int A[3]; // global {array starts at 1}

PROCEDURE P1 ( int x, int y)

BEGIN

y := 2;

i := 3;

PRINT(x, y) // #1 function prints the values of both x and y

END;

BEGIN //main

A[1]:= 7; A[2]:= 13; A[3]:= 11;

i := 1;

P1(A[i], i); // first call

PRINT(i) // #2

PRINT_A(A); // #3 assume function that prints the values found in the array A

P1(i, A[i]); // second call

PRINTT(i) // #4

PRINT_A(A); // #5 assume function that prints the values found in the array A

END.

a) x is passed by name and y is passed by reference.
