      Just for curiosity, could you add #include <string> and try:

      // enter the temperature in Celsius
      int celsius;
      string celsiusString;
      cout << "Enter the temperature in Celsius:";
      getline(cin,celsiusString);
      celsius = stoi(celsiusString);

        @SGaist

        With console I mean the application output of QT.
        As I said it shows the text "Enter the temperature in Celsius:" correctly but doesn't do nothing when I write a number and press enter key.

          @itzalak2 As far as I know you cannot enter there anything. Check the "Run in terminal" checkbox in Run settings of your project.

            Thanks to all. Definitively you can't input anything through the console so I have to use the terminal.

            One thing I find horrible is that when I run a simple app, QT launches the terminal but there is a very long message and I was asking if there is a way to avoid it.

            I attach a capture, there you can see what shows the terminal when is launched by QT.

            terminal

              @itzalak2 What is the problem with this message? It is just what QtCreator is doing in the terminal to start your app. It will not be there if you start your app manually.

                Yes, I know, but I would like not to show this loooooong message because it fills the 50% of the terminal screen. Is it possible to hide this message?

                Thanks for the help.

                  Like @jsulm wrote, it won't appear if you run it from a normal terminal.

                      @icebergenergy
                      Doesn't sound like anything related to this issue.
                      Assuming release\writeToDat.exe is your executable and the right path to it, have you looked to see whether you already have that executable running, perhaps left over from when you ran it outside of Creator? Use Task Manager to have a look at what processes are running. Restart your PC and see whether error has gone away.
