From Java to C++
WHEN I WROTE THE FIRST VERSION OF THESE NOTES in 1996, Java was still a very new programming language. Although it had already caused a lot of excitement, it's long-term prospects were not entirely clear. Now, in the year 2000, I think it is clear that Java is an important language and will remain so for the long term. However, it is true at least for now that most "serious" programming is done in C and C++. Fortunately, these languages share a lot of features with Java. The older language, C, has no object-oriented features. C++ is a much larger language, which extends C with classes, objects, and other features. This chapter serves as a brief introduction to C++ for someone who already knows Java. The coverage here is very incomplete, and is meant only as a starting point for learning about C++.
You'll find that a lot of the basics ("programming in the small") are almost identical in Java and C++. However, both the programming philosophy and the large-scale structure of programs ("programming in the large") in C++ are quite different from Java.
In the first and second editions of this text, this material on C++ was a full-fledged chapter in the text proper, rather than an appendix. It changed very little between the first and second editions, and is completely unchanged (except for section titles) between the second edition and the third.
Contents of this Appendix:
- Section 1: C++ Programming Fundamentals
- Section 2: Pointers and Arrays in C++
- Section 3: Classes and Objects in C++
