1 Systematically analyze the lifetimes of variables of your favorite programming language. Are global, local, and/or heap variables supported? What determines the lifetime of each variable?

2 Consider the following C program:
void
main () {

int
f;

f = fac(3);

}

int
factorial (int
n) {

int
p, i;

p = 1;

for
(i = 2; i <=>

p *= i;

return
p;

}

(a) Make a diagram, similar to showing the lifetimes of the local variables in this program. (Note that the formal parameter n is, in effect, a local variable of the factorial function.)

(b) Repeat with the above version of the factorial function replaced by the following recursive version:
int
factorial (int
n) {

if
(n > 1)
return
n * factorial(n-1);

else return
1;

}
