Like any human language, C++ provides a way to express concepts. If successful, this medium of expression is
significantly easier and more flexible than the alternatives as problems grow larger and more complex.
However, you can’t just look at C++ as a collection of features; some of the features make no sense in isolation.
You can only use the sum of the parts if you are thinking about design, not simply coding. And to understand
C++ this way, you must understand the problems with C—and with programming in general. This book discusses
programming problems, why they are problems, and the approach C++ has taken to solve such problems. Thus,
the set of features I explain in each chapter is based on the way that I see a particular type of problem being solved
with the language. In this way I hope to move you, a little at a time, from understanding C to the point where the
C++ mindset becomes your native tongue.
Throughout, I’ll be taking the attitude that you want to build a model in your head that allows you to understand
the language all the way down to the bare metal; if you encounter a puzzle, you’ll be able to feed it to your model and
deduce the answer. I will try to convey to you the insights that have made me start “Moving from C to C++”.
