Which of the following are true?

I. A programming language which does not permit global variables of any kind and has no nesting of procedures/functions, but permits recursion can be implemented with static storage allocation

II. Multi-level access link (or display) arrangement is needed to arrange activation records only if the programming language being implemented has nesting of procedures/functions

III. Recursion in programming languages cannot be implemented with dynamic storage allocation

IV. Nesting procedures/functions and recursion require a dynamic heap allocation scheme and cannot be implemented with a stack-based allocation scheme for activation records

V. Programming languages which permit a function to return a function as its result cannot be implemented with a stack-based storage allocation scheme for activation records

The following program fragment is written in a programming language that allows global variables and does not allow nested declarations of functions.

global int i = 100, j = 5;
void P(x) {
    int i = 10;
    print(x + 10);
    i = 200;
    j = 20;
    print (x);
}
main() {
    P(i + j);
}

If the programming language uses dynamic scoping and call by name parameter passing mechanism, the values printed by the above program are

What is printed by the print statements in the program P1 assuming call by reference parameter passing?

Program P1()
{
     x=10;
     y=3;
     func1(y,x,x);
     print x;
     print y;
}
func1(x,y,z)
{
     y=y+4;
     z=x+y+z;
}
