I suggest you read a book on the basics of C++; this isn't the place to learn the fundamentals.

[ThePentiumGuy]

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?

[Volte]

It means it's 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. I'm sure you'll find tons of other good links by searching Google as well.
