    Question Masking Characters In Scanf

    i am at present working on an ATM paper in the IEEE transcation
    the problem is i need t mask the characters that appear on the screen with a "*" when the user is entering the pin

    i know that getpass could be used, but that only displays a blank
    screen

    can you please provide me a code that can mask a character simultaneouly as the user is entering a pin
    you can also mail your reply at shyam.cool@gmail.com

    This cannot be done in a standard way. I think that if you use a console API (is that the right term?) like curses/ncurses you should be able to do that. I also think that there are win32 console functions that may let you do it but I'm not sure about that.

    BTW: This board is here for a reason. No one is going to email a reply. If you go to your user control panel you should be able to 'subscribe' to a thread so that an email is sent to you every time a reply is posted.

    [B]but if you look at VB
    we can easily mask the characters in a text box
    perhaps there is a seperate library file in VB which
    just allows us to do that????
    by the way, what languge is used to write softwares for ATM's???
    i believe it must be in C

    any questions any type in programming

    a ready made answer

    Why are you moving to a new line in the middle of a sentence? Stop hitting enter.
    When no one helps you out. Call google();
