Need Help Getting New Line When Writing to File - c++

Question

I have the endl, but its not going into my file, so when I enter in more than 1 line, its all on the same line in the notepad.
I've tried:
codeFile << codeLine;
codeFile << endl;
I've also tried adding a "\n" to the string by adding a constant string to it but it doesn't work.
//Writing Coded Lines to File:
if(codeFile)
{
//Relaying Feedback to User:
cout << "File has been successfully opened/created" << endl;
cout << "\nWriting to file..." << endl;
for(int i = 0; i < lines; i++)
{
//Getting Non-Coded Line from User:
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
cin.getline(line, length);
//Creating Copy of Line:
strcpy(cline, line);
//Gathering Line Length:
length = strlen(line);
//Coding Line:
codedLine = code(length, line, cline, sAlphabet);
//Coded Line Test
cout << codedLine;
//Writing to File:
codeFile << codedLine << endl;
}
}
//Closing File:
codeFile.close();
cout << "\nFile has now been closed";
}

Cygwin mocks a POSIX system and uses Unix line endings, not the Windows line endings understood by NotePad.
Replacing endl with '\n' won't help. endl is a '\n' followed by a stream flush.
The best option is to use a different file reader, WordPad for example, that understands Unix line endings. The alternatives are to
Change your compiler toolchain to one that is not emulating a POSIX operating system, or
Brute force a Windows line ending with \r\n, but this means your code will have a similar wrong line-ending problem on a Unix -based system.
