Rust. For sure, otherwise stick with C. Having programmed in C++ for a long time (but no more!), I think it has too much baggage (compiler support / versions / platforms etc) and the ecosystem isn't as good as Rust's. C is just C and you need to know it from a first-principals point of view, but it's terribly unsafe compared to Rust (kind of like driving in a 60's convertible with no seatbelts or ABS).
