Hello RK.
If programming is what you wish to do , then there is a variety of courses you can opt for. You can start with a language of your choice and learn the very basics until you are absolutely comfortable.
Then you can go for Data Structure and Data Algorithms for higher knowledge. Once you are no more a beginner try competitive programming, which is a must for becoming a good programmer.

And this is apart from what is taught in any UG course which is CSE or IT.

Hello,
If you are that interested in programming opt CSE. You can also choose Information technology. Go through the course catalog of type college you want to join in and then pick a branch that fits you best.
Good Luck!

Computer engineering  and information technology engineering is the course for you if you want to make your career in programming.
