C++ Programming

I have programed in C for many years. I recently undertook the task of rewriting a modeling program to have a GUI. I adopted the FLTK, a C++ framework, for the GUI portion of the program. To use FLTK, I had to learn about classes, objects, inheritance, virtual function, etc. I started reading Ullman & Signer in Chapter 7, Introducing Objects, and found these topics clearly discussed and explicitly demonstrated. My program is to be run on multiple platforms, and Ullman & Signer discuss development for multiple platforms. I posted a question on the book's forum page and received an answer in about a day. Previous reviewers have commented negatively on the format of the book and that it does not give an exhaustive treatment of C++. I mostly agree with those comments, but the book worked for me.
