Yeah right.
If your account is "hacked" you should immediately inform an administrator, who can restore your email address and reset your password. I will lock that account seeing as you have given up on it.
The homework section is here for people to ask why they are having problems with their assignments, not so they can post lists of questions and covertly demand the answers to them. That's why you are encountering resistance.
The questions you have posted are simple ones, so if you are just going to copy answers off the web I suggest you use the Wikipedia. You won't learn anything from the exercise, but at least you'll be aware of a good resource.
