The horror of C + + language

Turn from: http://coolshell.cn/articles/1724.html

Linus once (September 2007) in the newsgroup gmane.comp.version-control.git and a Microsoft Engineer (Dmitry Kakurin) in a dispute between C or C + +, The Microsoft engineer at the time was primarily working on Git's Windows version, but he found that Git's source code was written in C rather than C + +, so he posted a kakurin in the Linux community expressing dissatisfaction with Linux, which was straightforward:

Pure C as opposed to C + +. No idea why. Please don ' t talk about portability, it ' s BS. (Pure C Write, not C + +, do not know why, please don't tell me is for transplant sex, this is completely nonsense.) ）

Linux father Linus Torvalds immediately posted, in the post, Linus words very direct, direct that C + + is a very scary language, he said in the post:

*you* are full of bullshit. C + + is a horrible language. It's made more horrible by the fact, a lot of substandard use it. (You're the absolute nonsense.) C + + is a very scary language, and more frightening than it is a lot of unqualified programmers are using it.

Linus this point of view I am more agree with, I personally also in a few years ago, "STL string writing Copy" and later in some articles expressed in C + + is indeed not a very mature language, this view has been around me. This is because its learning costs are too high, the compiler and class behind you do a lot of things you do not know, and, C + + is very easy to make mistakes and many unexpected problems occur.

Of course, this article is not to continue to denounce C + +, nor to review an earlier event. We only talk about technology here. Yesterday, I saw an evil example of C + + on the Internet, here to give you a share, let you see C + + programming language of the horror and evil side. The following example is more sinister than the "#define private public".

Please look at the code below, can you tell me what it will output. (Note the highlighted line in the main function)
