You can also write object-oriented code in C. You don’t get all the C++ goodies and it’s ugly, and you have to manually pass the this pointer (I’ve seen
selfused for this, in order to make it compatible with C++), but it works. So technically, you don’t need global state in pure procedural languages for the very same reasons you don’t need it in object-oriented languages. You just have to pass the state around explicitly, rather than implicitly like in OO languages.
