1) The assignment states that "The phases must be completed in order",
since looping is easier to implement, can that come before arrays?

2) Is boolean input required?
ex. bool x;
x <-- in();

3) Any tips for allocating space for dynamically sized arrays ?

Yes. Some phases are dependent on previous phases, but your free to do the
bonus in any order. I expect that many of you will do the recursion and
the looping bonus...Only a few will try for the array bonuses.

Yes.

First off, here is the only way to get a dynamic array:

void a ( int x )
begin
int b[x];
end;

Dealing with this is not that hard. Just compute the expression and
allocate space on the stack...Unless you done something tricky, I don't
think the code is any different than handling:
begin
int b[1+3+5];
end;

...but I haven't got around to the array bonus yet.

Yes.

In the CS241 newsgroup, Chris Ingram indicated that "There is no "in" for
booleans." (Posting Jul 10 8:29PM). Can I get a clarification?

[Troy Mark Gonsalves]

I'm sticking with my answer.

But you don't have to verify that the values
the user types are 1 or 0....That should make things simple enough.

I was under the impression that input can only take a decimal input and a
single character as the specs state.

"Execution of the statement consists of reading either a number expressed
in decimal or a character from the standard input stream and storing it in
the specified variable."

Unless you want to treat 1s and 0s as true/false values, it seems like you
cannot input a boolean.

We already treat true and false as 1 and 0 for output...I see no problem
with doing the same for input.
