Autograd project [P]

Hello, I'm a 3rd year Highschooler interested in machine learning and for the last few weeks have been working on a small project meant to learn the basics of machine learning. I have implemented a simple tensor library and autograd in c++. It's very simple but i want some advice on people who are interested in machine learning and c++. Any advice and or constructive criticism is welcomed. (sorry for any mistakes english isn't my first language) github.com/Ak0-m/autograd_in_cpp
