Just personal tastes. std::string is little more convenient.

Usually char array (C style) used, when its needed to read, write big text fast.

    Read in char* buffer, then std::string s = buff.

        scanf() is C function, it does not know C++ class string. The only way to read C++ string is to say where to write data, but it is unsafe. So, there is no direct way.
