The C++ standard for the F-35 Fighter Jet [video]

TL;DR

- no exceptions

- no recursion

- no malloc()/free() in the inner-loop

i.e. standard practice for every C++ code base I've ever worked on

What industry do you work in? Modern RAII practices are pretty prevalent

What does RAII have to do with any of the above?

0 allocations after the program initializes.

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.
