Currently. I am making a C++ project that uses ofstream in a function that is used to create a text file. You use your enter input to make a new line of text for the file ofstream rather than it passing the input off.

Currently, my familiarity with ofstream is that you can use the .write() function to pass a variable in to write. In my program, the variable I am using to pass in uses a std::getline() function to count std::cin input into filetext. The issue with this however, is that it removes the newline character once you press enter so it ends up not passing into the ofstream. (Could std::cin itself be the solution?)

Here is the code snippet of the function:

void createTextFile(std::string path) {
    std::string filename = "textfile";
    std::string filetext = "";
    std::ofstream outfile;
    int charcount = 0;
    std::cout << "What would you like to name the file?" << std::endl;
    std::cin >> filename;
    std::cout << "== WRITE MODE INSTRUCTIONS ==" << std::endl;
    std::cout << "Press enter for a new line, if you want to exit and save.\n"
                 "Type /s at the end of the file, otherwise you can type /e \n"
                 "at the end of the file to exit without saving." << std::endl;
    while (true) {
        std::cout << "> "; std::getline(std::cin, filetext);
        charcount += filetext.length();
        debug_printCharCount(charcount);

        // -------------------------
        // SAVING IF STATEMENT START
        // -------------------------
        if (filetext.size() >= 2 && filetext.substr(filetext.size() - 2) == "/s") {
            // substr gets position of the first character, up to the end of the text to look for /s

            // ----------------------------------------------------------------------->
            // Nested if statement for checking if there is a extra slash before the /s
            // -----------------------------------------------------------------------
            if (filetext.substr(filetext.size() - 3) == "//s") { // Double slashes are used just to include /s
                continue;
            } else {
                outfile.open(path);
                if (outfile.is_open()) {
                    outfile.write( filetext.c_str(), filetext.size() - 2); // INFO: c_str returns a read only pointer to the array of characters that string is.
                    break;
                } else {
                    std::cerr << "ERROR: File " << path << " could not be opened." << std::endl;
                    break;
                }
            }
        }
        // -----------------------
        // SAVING IF STATEMENT END
        // -----------------------
    }
}

Once you get to the while loop, this is where the enter button gets used for making a new line in the text file. So each time you press enter in the input. It makes an arrow like this: >

And you basically type after it for a new line to be added to the text file each time.

But from this code alone, it seems like if I input:

> Hello world!
> My name means the world to me!

It will likely write to the file as:

Hello world!My name means the world to me!

So what is the best approach here to make it to where you can utilize this enter button to make it so the text file can separate each line you type.

Hello world!
My name means the world to me!

I would also like to learn some methods to make this function better optimized. The function doesn't quite work yet since it throws errors. But I wanna figure this out alongside fixing it.
