Hello, Adarsh!

It depends upon your choice!

At first, you will have to decide that- in which things you have an interest. depending upon that you can choose your engineering course or branch. If you will get the branch according to your choice then will enjoy engineering, otherwise fell like a burden!

If you will see according to today's tradition, economically and requirement Computer Science Engineering(CSE) will be better for you.

Roles are varieties for Computer engineers in IT sector, but their primary role is to apply the knowledge of mathematics and science to design and develop software to be used by clients or users. There are network engineers , system management professionals besides the computer engineers .

All the best!

Hope this helps!
