My code is reading and printing everyline and printing it two times.How can i fix it?

    string line;
    fstream inputNumbersFile("input.txt");

    if (inputNumbersFile.is_open())
    {   
        while (!inputNumbersFile.eof())
        {
            getline(inputNumbersFile, line);
            cout << line << endl;
        }
    }

Using of inputNumbersFile.eof() in loop condition is a bad idea. Just replace this loop with something like

while (getline(inputNumbersFile, line))
    cout << line << endl;
