What is the language that will be using in the CS courses mainly?
Check the course catalog online for descriptions. You may be able to choose one of several for a course beyond the intro courses. Once you finish your degree and enter the workforce you may be learning more computer languages on your own as they apply to the workplace. I know my son has. It seems that once you know how things work it is fairly easy to add different languages. Some months ago there was an article I read that had a chart that showed where several CS languages are used- it depends on the country and the field for which are most popular.
