    Question simple username password program

    I need to write a simple username password program, and I would like the characters to appear on the console as * not the character typed. I would really like some help with this, thank you.

    Okay, you have to show what you have done so far - them's the rules - its not a hire board
    Thought for the day:

    You need to use some kind of library for that, unfortunately. If you are on *nix, I think readline will be able to do it:

    The GNU Readline Library
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    Well... get started, work the problem as far as you can, then if you run into trouble post your code and we'll see what we can do...

    It is important to note that there is no standard C way of doing this, however:
    FAQ- How do I get input without the user pressing enter?
    Salem and Andr0id like this.

    Is there a standard way to not show any characters at all during the input ?

    If you mean standard, as standard C; the answer is no. Once you actually want to mess directly with any stream you have entered OS specific behaviour because you have to "look behind the curtain" to interact with the OS and/or hardware.

    Thank you this was exactly what I needed. I didn't post code because i had no idea where to start, all I expected was some pseudo code. This was much better thank you all for the help.
