I have had a fair amount of experience in SCHEME, a derivative of lisp,
and therefor have a pretty good understanding of object oriented code.

As part of a graphics class I need to write an interactive graphics program,
I have implemented the first part in straight C, but I realize that it
would be much more efficent to code in C++, as to the niceness of
using objects in a graphics interface.

I am worried about two issues though, the program will be quite long,
supporting
2D and 3D animation, so there will be a question of how easy it is to debug
the code that C++ produces.  Also, is there any tradeoff in the speed of
accessing lists of objects, as opposed to accesing the structures in an
array in straight C.

Finally, even though I have an extensive background in C and object oriented
code, what kind of learning curve should I expect learning C++.
