The Basics Of Input/Output Operations In C++ Using Iostream
WebThe class template basic_ifstream implements high-level input operations on file-based streams. It interfaces a file-based streambuffer ( std::basic_filebuf) with the high-level interface of ( std::basic_istream ). A typical implementation of std::basic_ifstream holds only one non-derived data member: an instance of std::basic_filebuf WebNormally, for binary file i/o you do notuse the conventional text-oriented <>operators! It can be done, but that is an advanced topic.
