This comment only fans the flames of language war, it doesn't contribute to the discussion.
But your thoughts are still valid and contribute to the conversation.
You literally cannot give any examples of correct C code as a solution to a problem: literally, experts will disagree with you.
I've had experts tell me that cplusplus.com/reference gives horrific examples you should never follow. The newest addition of The C++ Programming Language says that the examples are not meant to be production code you can actually use as-is. (I can dig this up later if you want.)
C and C++ are more debates in the form of a language than languages per se.
I would think you're being downvoted because there aren't really any language wars around the choice of C/C++ - it's not like PHP vs Ruby or Python or something. You're imagining a war where there really isn't one.
Usually people writing C or C++ don't have much of a choice, and usually people choose these languages due to the requirements. For example, writing embedded microcontroller code that will run on a $0.70 chip. What are you going to do, write it in Rust?
Nobody would dream of telling Linus Torvalds to refactor the Linux kernel into some other language - it's not just a ridiculous suggestion, it's like asking the United States to move to a different continent - it's a total non sequitur, it's not even in the realm of possibility.
Basically the advice "you should avoid writing C if you can" is totally uncontroversial, and for I would say 99% of people who woke up today, January 15th, 2016, a weekday, and wrote C code, the answer to "can you avoid it" is no. (Not just due to their position/employment but due to the very requirements of the project itself.)
Sure you should avoid writing C and C++ when you can, but for some classes of problems that is "never."
Haskell comes to mind. There's a denomination and a religion. I'm not sure that the gospel runs to hundreds of pages, but there are many prophets who tell you that you need to know category theory, so for that sect, yes, it's hundreds or thousands of pages.
Lisp also has a denomination and a religion, but the sacred texts may be shorter.
I challenge you to show me one!
My impression is that Haskell "experts" here say some variant of "of course all this is obvious because category theory" (implying "you have to know category theory or you're an uneducated heathen") at least three times as often as they say "you don't really need to know category theory".
