| Class | Use |
|---|---|
std::ifstream and std::wifstream |
File stream for the input of data of type char and wchar_t. |
std::ofstream and std::wofstream |
File stream for the output of data of type char and wchar_t |
std::fstream and std::wfstream |
File stream for the input and output of data of type char and wchar_t. |
std::filebuf and std::wfilebuf |
