What a lot of people don’t get is that it’s not pointers or manual memory management or even lack of language level support for “modern features” like object oriented programming, exceptions etc. that make C a pain to use. No it is the undefined and implementation dependent behaviours. There are simply so many of them that even experienced C programmers may, at times, run into trouble.

C is essentially a portable assembler. It’s not enough to learn the language, you need to have deep understanding of the underlying hardware and compiler infrastructure.
