Most likely C/C++, Java, or it's also possible that they will be teaching Python.
C and C++ are close to the hardware languages with fast efficiency. I believe that Java is pretty similar to C/C++, and everybody knows why everybody likes Python so it's permeating university.
In Introduction to Computer Science I learned C,
and in Introduction to Computer Science 2, I learned C++. This course was much harder than the first.
I've also taken Introduction to Informatics at my university, and the course was all about Python.
You learn how to program in a computer language, yes, but it's mostly focused on logic of programming and how you can implement it ... not so much on the perks of a particular language.
