I somewhat agree with that, but unlike in most other modern languages, type-safety is not enforced, thus you can't call it a pure type-safe language even though you can write programs in type-safe way. Same with low/high level -- you can use C++ as low level (C with classes) or as high level according to modern C++ standards (C++11, C++14) and best practices. There's no strict classification, I just wanted to highlight C++ similarities with C.
