This is my first term at CSULA but I've been programming for a while. The 'right' programming language to learn is dependent on which field you are aiming for (i.e. websites, software, or databases). In my past projects, I have mainly used C++ and Java. As a recommendation, focus on learning concepts like flow control, looping statements, and other programming concepts because each language is slightly different in how they implement them. 

Side Note: Java is a easy to learn and understand so it would be a good place to start.
