modern_pascal_introduction.pdf下载

There are many books and resources about Pascal out there, but too many of them talk about the old Pascal, without classes, units or generics. So I wrote this quick introduction to what I call modern Object Pascal. Most of the programmers using it don’t really call it "modern Object Pascal", we just call it "our Pascal". But when introducing the language, I feel it’s important to emphasize that it’s a modern, object-oriented language. It evolved a lot since the old (Turbo) Pascal that many people learned in schools long time ago. Feature-wise, it’s quite similar to C+ + or Java or C#. • It has all the modern features you expect — classes, units, interfaces, generics… • It’s compiled to a fast, native code, • It’s very type safe, • High-level but can also be low-level if you need it to be.
