Okay, I think this reply helps frame your stance much better. You are not necessarily proposing no C ever, but saying at least start a new project with a C++ compiler / IDE and if there are reasons to use C code or rules like "don't use dynamic memory allocation", when there is a substantial reason, then that is acceptable

There is no connection between C++ and dynamic memory allocation. Most of my C++ programs allocate memory at startup, then run for weeks or months (on machines with 200+ GB of RAM) never allocating ever again. C programs routinely allocate dynamic memory, except where there is reason not to; likewise C++.

So, no, there is never a reason to confine yourself to the C subset, in a new program. "for (auto e : v)" is universally better than "for (i = 0; i != N; ++i)". Zero cost, better code.

But I would never, ever suggest using an IDE, under any circumstances, for any language.
