I now want to create an application that will open a .txt file and write something in it, then refresh the .txt file and write something else in the file.

This is what I have done so far:

ofstream file("file.txt");
    system("start file.txt");
    file << "Hello";
    for (int i = 0; i < 3; i++)
    {
        sleep_for(1s);
        file << ". " << endl;
    }
    return 0;

and these are libraries and namespaces:

#include <iostream>
#include <fstream>
#include <windows.h>
#include <chrono>
#include <thread>

using namespace std;
using namespace this_thread;
using namespace chrono_literals;

You mean like a flush? – Apr 19 '19 at 17:13
file.flush() should do it, if that's what you're asking. – Apr 19 '19 at 17:15
What do you mean by refresh? Possible duplicate of https://stackoverflow.com/questions/2393345/how-to-append-text-to-a-text-file-in-c – SyntaxVoid Apr 19 '19 at 17:15
`endl` will flush the file. – Paul Sanders Apr 19 '19 at 17:17
by refresh I mean to open and close the file(to uppdate the file) – WOLFdesigne Apr 19 '19 at 17:18
I do not want to go to another row, I want to write something in several phases (to a second to show up " . ") – WOLFdesigne Apr 19 '19 at 17:24
but how do I do that? – WOLFdesigne Apr 19 '19 at 17:41
If I'm understanding you right, then you do mean flush(). – Apr 22 '19 at 05:31
