Your ONE programmer knows C.

If this ONE programmer is the only ONE who will program this year, then C++ is the way to go.

If you are planning on having more programmers, especially those who haven't programmed much before, then LABView is an easy language to learn, so I hear.

OR, if your current ONE programmer is capable and willing, they could teach others how to program C++, however it is tough to find a good teacher in most students when it comes to programming C++.

Notice the ONE word I put in all caps? My little bit of advice to you: If you can, have more than ONE programmer. It's an important job that requires lots of work and skill, and for some strange reason robots won't run without it.
