Bjarne Stroustrup Reveals All On C++
An anonymous reader writes "Bjarne Stroustrup, the creative force behind one of the most widely used and successful programming languages — C++ — is featured in an in-depth 8-page interview where he reveals everything programmers and software engineers should know about C++; its history, what it was intended to do, where it is at now, and of course what all good code-writers should think about when using the language he created."
I was kind of interested in the comment that C++ required a proper compiler rather than just a pre-processor macro package. From the fog of my memory I remember many of the early commercial C++ offerings being mostly a pre-processor package, were those really just C with Classes compilers rather than true C++ ones?
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
First, read the printable version of the article on one page. The original version is one paragraph per page, surrounded by ads and related dreck.
There's really nothing new there. It's the usual Strostrup stuff. He's still in denial about C++ being the cause of most of the buffer overflows, system crashes, and security holes in the world.
The fundamental problem with C was the "array=pointer" concept. If array sizes were carried along with arrays, we'd have far less trouble. Even FORTRAN has conformant array parameters. That should have been fixed in C++, but it wasn't, and as a result, we had two more decades of buffer overflow problems. This isn't a performance issue, by the way; Modula 3 got it right, but Modula 3 disappeared for non-technical reasons - Compaq bought DEC and closed down the software R&D operation.
C++ is also the only language that has hiding ("abstraction") without memory safety. C has neither; almost all later languages (Java, Delphi, all the scripting languages) have both. C++ stands alone in this unsafe place. Nobody ever repeated that mistake. So subtly incorrect calls to objects can result in the object overflowing.
Yes, some of these problems can be papered over with templates. The C++ committee is full of templateheads, focused on template features that few will use and fewer will use correctly and productively. That crowd is still struggling to make auto_ptr work.
