    Red face Filling the cin stream with a default value

    I would like to fill the cin stream with information so that you can edit values without typing them all again. Is this possible?

    No, not in standard C++.

    Look at the GNU readline library, though.

    Are you talking about files? If not, then please be a little more clear.

    The cin stream is the standard input stream that takes input from the console

    Re: Filling the cin stream with a default value

    But what do you mean by filling, exactly?

    Re: Filling the cin stream with a default value

    It is so the old value can literally be deleted, like with textboxes but without the mouse support

    Re: Filling the cin stream with a default value

    Sounds more like curses than readline, then.

    Either way, standard C++ doesn't support such things. cin is a linear stream - you cannot even seek in it.
