I like to introduce myself, in C++ circles, by mentioning I was using C++ before Microsoft had a C++ compiler. It's often interesting to watch people try to handle the concepts behind the sentence - mostly, that for some languages you can buy compilers from more than one vendor. And once upon a time, C++ existed as a language, and Microsoft sold compilers, but it didn't have a C++ one yet. Then eventually (OK, in 1992) the C product Microsoft sold became a C/C++ product (compiler, linker, debugger etc) and then the next year Visual Studio came along and with it Visual C++. And Visual C++ 1 included the Microsoft Foundation Classes 2, so that for a while the version numbers of Visual C++ and MFC were out of sync. Eventually there was a version skip to catch up (there was no Visual Studio 3). For quite a while we all worked with Visual C++ 1.52c and every speck of that version number was significant. So as you can see, the version of a product is not a simple question with one answer.
So, here we are, welcoming Visual Studio 2010. Lots of people called it Dev10 while it was under construction. But was the 10 short for 2010? It was not. It was just 10, as in the number after 9. Visual Studio 2008 was 9, and Visual Studio 2005 was 8. You can see these numbers on the shortcuts to your sln files, by the way:
OK,so VC8 means Visual C++ 2005? Basically. As long as you realize that it doesn't mean version 8 of the compiler. Because the C compiler transitioned into the C/C++ compiler, the version numbers came with it. VC8 includes version 14 of the compiler. Confused yet? If so, you're in good company. Here's a tabular explanation, though it only goes back a decade. You want more details? Wikipedia has them, of course. Me, I am going to enjoy Dev10 and watch for news of Dev11.
