I suggest you read a book on the basics of C++; this isnt the place to learn the fundamentals.

yeah but..

i am reading a book the book simply states that you use mypointer->dosomething to dosomething!

fundamentals? Does that mean its a hard concept or easy concept?

It means its part of basic C++ that every C++ programmer needs to know, and this is not the place to learn about them.

Try looking here here. It took about 45 seconds to find that on Google. Im sure youll find tons of other good links by searching Google as well.
