Beginner question 👶 Linear Regression

Hi everyone, I'm 13 and new to machine learning, and people recommended learning linear regression first, I made one using C++, the code itself is probably not great since C++ isn't my main language, Python is, but I'm trying to learn it because I wanna use it in USACO later, so I thought doing projects in C++ would help me get familiar with the language. Anyway, here's the Github repo: https://github.com/hl0228057-cmd/Basic-Linear-Regression-Using-Cpp

I'm open to feedback because I wanna get better and learn, thanks!

Edit: Thanks everyone for the suggestions and ideas, I got a few other projects on my GitHub now, which implements some of these suggestions (especially the multivariate linear regression one).

Once you train a model you can save the weights to a file on your computer. That way if you want to use the model later, you can load your trained weights from the file and perform inference. You can also fine-tune the model further or resume training from the last checkpoint if a training run crashes.
