Hello there,
If you want to learn coding or Ethical Hacking, your first step is to learn the programming languages and learn how to code the basic programs. You can join any tuition or learn by watching YouTube videos. You can get plenty of videos where they teach you the basics of coding. You can find them on various websites too. Start with languages like python, C and C++, these are easy and used frequently. Once you learn how to code, you need to practice to be efficient in that. Then you can join a course for Ethical Hacking. There are various colleges offering this course. The scope for Ethical Hackers is quite good.
Hope this information helps you.
Good luck!!
