I strongly disagree. C++ has very nice tools for abstraction: higher-kinded types, dependent types (to some extent), lambdas & function objects, overloads, etc. It's a pain to design a data flow in C, but in C++ for instance it can just be something like this : https://github.com/RaftLib/RaftLib/wiki/Linking-Kernels https://github.com/RaftLib/RaftLib/wiki/Linking-Kernels or this : https://ericniebler.github.io/range-v3/ https://ericniebler.github.io/range-v3/.
