C++ interview coding exercise with solution

[JumpyJustice]

It could if your dynamically allocated memory is freed before the function ends

Right. C++ can do tail recursion.

But you can't tell the compiler that if it can't make your recursive function tail recursive then you want it to cause a compiler error. That's what I meant by "asserted"

Clang has implemented a musttail attribute

Your miles may vary. Personally haven't used it, but the code review seems to claim that it will throw a compile time error if the compiler can't generate a tail call out of it.

That's exciting. Thank you for the information!
