Things may have changed, but last time I looked at Cling you were limited in what you could do in the REPL. The main way I think it is used in practice is to slurp in a pile of C++ from files, and then inspect values in the REPL. As I say, this may have changed now.
The other thing to consider is that C is not really designed for use in a REPL. I personally use it more than any other language, but I don't personally feel that I would get much more out of it if I had a C REPL.
Having said that, C has no realtime features, and there are a lot of interesting potential applications if you have the ability to eval C code at runtime.
