How would the number 2321 be spanned through memory? and the answer is:

1st byte 9 and 2nd byte 17

What do they mean by this? I've looked through the section again and do not understand the question or the answer.

Also it asks:

What would be the result of the following operation:

int Result, a, b, c;

a = 9;

b = 1;

c = 2;

Result = c-- + (b++ - --b) * a + c

They have the answer as 11, but I have the answer as 21. Can someone explain to me how they have that answer and what I did wrong. Here is what I did:

first I did my post and prefix operation which make the problem like this:

result = 2 + (1 - (-1)) * 9 + 1

result = 2 + (2) * 9 + 1

result = 2 +18 + 1

result = 21

The b gets added 1 to the taken directly away again right??? since it is a negative 1 then it is added to to make a 0 and then taken from to make a negative 1 again and then 1 - negative 1 is prositive 2.

The c's are 2 and 1 which make 3 right? I'm confused.

Thanks for any help.

Nice board!
