C++之父元旦专访（8+13个问题，关于C++的学习&使用和未来）

临近元旦的一个月，Bjarne在通信中答应接受一次访谈。高兴之余，为访谈的问题犯了难，我不想做成一个个人的访谈；我希望这次访谈能够代表更多的人，最好能够代表国内C++社群的一些典型的声音，同时我也希望问题是经过深思熟虑的，由真正了解C++的人提出。

所以，当时我便在blog里面放了一个问题召集的声明，并在TopLanguage讨论组上置顶了一个帖子。向大伙征集好问题。一个月后我们有了一个问题集，我又邀请云风和孟岩各提了一个问题。

经过整理，一共有8+13个问题。前8个问题是关于C++的学习和使用。后13个问题是关于C++的未来。Bjarne在收到问题集之后称赞问题很好，并很快作了回答:-)

我相信这是一次非常特别的访谈，因为两个原因：1. 并非代表我一个人的观点，而是来自许多人（问题贡献者附于相应问题的后面）。2. Bjarne的以往的很多访谈更多倾向于技术和现状；但我们这次的访谈几乎不谈技术，而是着眼C++中最大的问题：学习和使用。以及另一个更大的主题：C++的未来。

 

以下是访谈全文。中文版预计见于下期程序员杂志。

 

Bjarne Stroustrup is the designer and original implementer of C++ and the author of "The C++ Programming Language" and “The Design and Evolution of C++”. His research interests include distributed systems, design, programming techniques, software development tools, and programming languages. He is actively involved in the ANSI/ISO standardization of C++.

Dr. Stroustrup is the College of Engineering Chair Professor in Computer Science at Texas A&M University. He retains a link with AT&T Labs – Research as an AT&T Fellow. Member of the National Academy of Engineering. ACM fellow. IEEE Fellow.

Part1: On Learning and Using of C++

1. Why do you go to TAMU to teach programming? What’s your favorite thing about the university? – xingranliuyun

It was time for a change and I felt I had something to teach. I had friends at TAMU and it was one of the few universities that seemed serious about growing and improving. Some of the most enjoyable work has been designing and giving a first programming course to 1^st year students.

2. Undeniably, the biggest problem of C++ is learning. Language-lawyer is a phenomenon that appears almost solely in C++. Many C++ programmers wasted so much time fighting against the language details, of which some are essential and some are unnecessary. C++ has many traps which we have to bear in mind before we can safely use it; C++ has so many pitfalls which leads to a tremendous amount of language tricks (some might call them “idioms” or “techniques”); they, together, lead to a very steep learning curve. Confronted with so many complexities, how can one learn and use C++ effectively from a practitioner’s perspective? -- pongba&liujiang

You may be accurate about the complexities of using C++, but then you may also be underestimating the trickery involved in learning and using other languages. Some problems only surface when the user population gets large and diverse. Also, C++ is used in a huge range of application areas and often the alternative to C++ is to learn several languages
