I want to study ethical hacking
Hello Aspirant,
To become an Ethical hacker you need to do systematically your study. You can go for c, c++, python and data structures then go for training courses in Ethical Hacking and Information Security also prepare for certifications also along with a full time degree course either B.E/B.S./B.Tech or BCA/BSC(IT/CSE).
Good Luck!
