Пример использования CStdioFile

CStdioFile Inputfile, Outputfile;
CFileException FileExc;
UINT nOpenFlags;
CString s;
nOpenFlags = CFile::modeRead;
if (!Inputfile.Open("Console.txt", nOpenFlags, &FileExc)) {
FileExc.ReportError();
return;
}
nOpenFlags = CFile::modeWrite | CFile::modeCreate;
if (!Outputfile.Open("Output.txt", nOpenFlags, &FileExc)) {
FileExc.ReportError();
return;
}
while (Inputfile.ReadString(s))
Outputfile.WriteString(s+'\n');
Inputfile.Close();
Outputfile.Close();
