Open a file in the constructor, close it in the destructor. RAII with 0 allocations.

std::vector<int> allocated and freed on the stack will allocate an array for its int’s on the heap…

I've heard that MSVC does (did?) that, but if so that's an MSVC problem. gcc and clang don't do that.

WDYM? Vector is an abstraction over dynamically sized arrays so sure it does use heap to store its elements.

Sure, but my point was that RAII doesn't need to involve the heap. Another example would be acquiring abd releasing a mutex.
