You just proved the claim that there are many GUI apps written in C++ on OS X and X Window platforms, which is, incidentally, not the claim I find false. What I find false is the claim that almost all GUI apps are written in C++.

Can you find one app on your computer that is not written in c++?

[xyzzyz]

Why, of course. What's more interesting, I can find only one GUI app on my computer that is (probably) written in C++, the web browser I use.

Why do you ask?

His argument is that if he's using a Mac, a lot of them are written in Objective-C.

And if he's using Gnome in Linux, most are written in C.

But for Windows apps, commercial apps, cross platform and games, C++ leads by far.
