good first book to learn c++??

Decent hold on C++ by next week? Tall order, especially seeing as you have to do manual memory management and the joy of pointers neither of which Java has (as far as I am aware).

You could start by reading http://www.cplusplus.com/ though.

 

just google C++ for Java programmers

 

I've used many books, but have found Deitel & Deitel to have the most detailed, while being the most understandable out of all the books. They are thorough and cover everything. I just recently bought C++ How to Program 6th edition by Deitel & Deitel as a reference. It's a wonderful book, and unlike most books, they start you off with the core of C++ in classes and the concept of object oriented programming. They provide LOTS of examples, case studies and a long term project throughout the book.

Check it out for yourself, here's the book directly from their site but perhaps you can find it in a bookstore. I'd recommend checking it out first in person, because it's a really good book, you'll understand once you read it. Not filled with technical jargon that uses terminology as though the authors assume you understand.

I suggest you start with www.cplusplus.com ,too. But as you progress through the language you will see that you can never, EVER say that you know good C++. There are always things to discover and things to master. I doubt that even Bjane Stroustrup has taken advantage of all C++ features to a big extent.

2 weeks is a very tight deadline in my opinion.
