Question 1 is really simple:
foo is wrong, thus cannot compile :-(
In one case foo expects a number, in the other recurse with empty stack
(with no input parameter).
Even fixing this, if you don't change some other thing, you would have
infinite loop.
This is what you wrote in C(++):
void f(int n) {
if (n != 5)
f();
}
what is f prototype ? :-)
