I am reading the first chapter on graphics in the Stroustrup book. He explains that we students will need to download the files of a GUI toolkit in order to run programs containing graphics. He recommends the "Fast Light Tool Kit, FLTK" because the book's programs are based on that tool kit.
I would like some guidance as to the variety of GUI toolkits that are available and how they compare to each other. Which are compatible with VC++ Express? Which are most suitable for a beginner to C++? Which are free? Thanks in advance.
