Hi Mahdi, I don't know any website that offer the answers free. The answers are on the Pearson's website but it is only for "Instructors". You can also find the answers on chegg but it is not free. There is also an incomplete set of answers on github (its free though).
The answers are posted here FREE and with explanations where necessary. This page is updated as new answers are posted. So, bookmark this page/add it to your favourite sites and check back often. I'll try and post the answers to the next few chapters as soon as possible.
I do not have problems with the assignments although it takes me longer to solve some. I would like to know the answers to the exercise questions that do not have answers in the book. Do you know of any website that offers these answers?
