I think you can take a look at this book which has a whole bunch of sample code of the three method you want in chapter 5


The book is called Modeling Derivatives in C++, it may help you and of course save money :-). If you still have trouble, you can come back and we can discuss.

楼上热心人

Thank you very much. Actually have this book in my room, however, I am a fool on programming and the codes on the book cannot be run on Visual studio directly. Moreover, I have too many exam in this month, and I really have no time to finish, so if you can, could you do me a favour, I will be appreciate that. thanks
