I think that all comp sci students should begin by learning to become competent in C. Aside from having the widest support across platforms, and being syntactically similar to many other languages, it's the closest you can get to understanding how computers work at a low level without dropping into asm. Frankly, knowing these things will make you a better programmer.
That said there is definitely a benefit to exposing students to higher level languages, both for productivity in solving more complex problems and understanding what the syntax and expressions of these languages have to offer. And by higher language I don't mean C++ :)
