CString + CFileOpenWriteClose

Answer 4

CStdioFile file;
if(file.Open("cwa.cfg",CFile::modeNoTruncate | CFile::modeWrite | CFile::typeText))
{
CString strbuf;
file.SeekToBegin(); strbuf = str1 + str2 ...;
file.WriteString(strbuf);
file.WriteString("\r\n");
         file.Close();
}

Answer 5

之际先把字符串相加，然后打开文件，写
file.open();
file.writestring();
file.close();

Answer 6

ostream out("Test.txt",ios::app); //追加到文件末尾
out<<str1<<endl;
out<<str2<<endl;
out<<str3<<endl;
out<<str4<<endl;
out<<str5<<endl;
......
out.close();
