This is not my experience at all. In fact, my experience is where C++ is used in GCC it became harder to read. Note that GCC was written in C and then introduced C++ features later so this is not hypothetical.

In general, I think clean C code is easier to read than C++ due to much less complexity and not having language features that make it more difficult to understand by hiding crucial information from the reader (overloading, references, templates, auto, ..).
