I just don't understand it, in this post for example http://tenaciousc.com/?p=1787 he is talking about poking around in the kernel, but then he develops a Windows-only C IDE? Qt is perfect, I don't understand what the problem is.

Is it that hard to imagine that maybe he's primarily a Windows user and has previous experience in C# and not Qt?

Hm, to me it is. If he knows C, he will know C++ too. Qt makes cross platform development trivial. Linux is a C stronghold. He knows the in&out of the Linux kernel, knows gdb and the gcc. He is making a C IDE, so why not program it in C with GTK+ if not Qt. Yes, all that stuff makes it hard to understand to be Windows-only.

What?

The two languages are only barely related as used in industry. Tons of people use C every day who wouldn't think about touching C++.

  C++ is rarely used compared to straight C in:
  OSes 
  Micro-controllers 
  Libraries

Lots of users of C also think C++ is a horrid mistake for many application development efforts (hard to find engineers who do C++ right enough vs most other languages).

And those same C people have rarely programmed in GUI environments as well.

I agree that C++ is horrible, but I was under the impression that everyone who knows C would have at least learned C++ before discarding it, making it possible to at least use C++ libraries.

Naw, tons of EE's know enough C to not have to do assembler, but don't get C++ at all. Lots of other people know C because they do extensions for their preferred language. Lastly people know enough C++ to know they don't know C++ well enough to release software in it.

C++ is vastly different from C. I know C, yet I don't know C++.

When I need a GUI I still use Tcl/Tk, nowt wrong wi' the old ways and it works a treat on Windows too.
