There are no double degrees at present. But many majors will have small majors to choose from (when they are freshmen and sophomores).
Take IB (International Business) as an example. In my sophomore year, there will be four minor majors to choose from: IBE IBM IBL IBC. In the medium term, E stands for economy, M = management L = language, and C = communication. The first two E's and M's focus on business, while the last two focus on language and communication. Many courses are the same as those of the College of Liberal Arts. But the theme is still IB business.
As for elective courses, different majors have different elective courses. For example, IB major has 6 courses every year (3 courses per semester), while FAM (Financial Management) in the same college has only two elective courses, with business as the main elective subject. The computer course you mentioned will be available in compulsory or elective courses, but it is not a pure computer course, but a business-related computer foundation (such as how to program with excel or make financial statements, etc.). ).
There is a major in computer science called CS (I can't remember, it should be something about calculation), which belongs to a major of Engineering College. This major seems to have more contact with pure computers, and there are also several elective courses that overlap with business.
I think which one to choose mainly depends on your plan bias, and the rest can be studied as an interest. There are many kinds of scholars in the school, so you can communicate more and find like-minded people ~
