1). Elaborate on the reasons why even parameters passed in registers may some- times need to have locations in the stack.
2). Consider the following function and call: procedure f(x, y, z) x := x + 1 y := z z := z + 1 . . . i := 1; a[1] := 10; a[2] := 11 f(i, a[i], i) print(i, a[1], a[2])
Determine the outputs of the program if arguments are passed
a) by value,
b) by reference, and
c) by name.
3). Consider the following program in C:
void foo() { int i; printf("%d ", i++); }
int main() { int j; for (j = 1; j <= 10; j++) foo(); } Check out the output in your system and suggest an explanation in terms of activation records in the stack.
