• C++ defines main as: "int main()" or "int main(int argc, char* argv[])". There's nothing in the code that limits us to Visual C++ and its non-standard "void main()" extension.
• Using std::getline (defined in "string") we avoid using a char* buffer as we have to with std::basic_istream<...>::getline.
• Invoking s.c_str() on something we write out using iostreams anyway might incur the following overhead: a char* buffer that can contain the contents is allocated, the contents of s is copied over into it, a terminating null character is added and this buffer is returned. This is because the contents of std::string isn't guaranteed to be null terminated.
