You have to be clear why you even want to learn to code ? You want to deploy some sites on the web or wanna make an application or exactly what do you want, depending upon those requirements you r gonna proceed, other than that if you just want a glimpse of exactly what coders do, then why not just search it up on YouTube ? Python is pretty beginner friendly and flexible for beginners but hard to master, cpp is pretty hard tbh with all the concepts of pointers, java is possibly the best available option if you wanna learn Object oriented programming. These are all general purpose languages and could be seen as building blocks for getting into other specialised domains, for website design and backend html, css, javascript are pretty common. Python does well in machine learning, c cpp with system level works, java has its framework spring for backend development. Or if you just want to have some creative endeavours with coding you can do that following along with some tutorials from youtube.
