Is autosummrisation tool is easy to make in c++?

Answer 1

I think you're asking the wrong thing? If you're wondering if it's possible to create it with C++, then yes, it's possible to do. Clearly you don't care if it's easy or not, because it's something you want and are going to make, right?

Answer 2
