Why use c strings in c++?

Question

Is there any good reason to use C-strings in C++ nowadays? My textbook uses them in examples at some points, and I really feel like it would be easier just to use a std::string

Answer 1

If a function needs a constant string I still prefer to use 'const char*' (or const wchar_t*) even if the program uses std::string, CString, EString or whatever elsewhere.

There are just too many sources of strings in a large code base to be sure the caller will have the string as a std::string and 'const char*' is the lowest common denominator.
