    Question Password, color

    Hi there,

    I having a school project on c programming. There is some part i don't how to do. Like how to put color to my text. And when like

    printf("Enter your password: ");
    scanf("%s",&passsword);

    Display:
    Enter your password: 1234

    can any on teach mi how to do this:

    Display:

    For the password part, try the FAQ.

    For the color part, search the boards.

    for getting string for an stream, use fgets().

    But they want unbuffered input, so standard functions won't do the job I'm afraid. They'll need getch() or an equivalent of some sort (as per the FAQ already mentioned).
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Hammer I meant, not about the **** and yes about the
    scanf("%s",&password);
    this is unbuffered too?

    Always when I write scanf("%s",&myStr); here, people always tell's me to change to fgets... wierd.

    That's buffered. Scanf (and variations of it) store any keypresses into a buffer, and when the enter key is pressed, they then deal with the buffer.

    Ok, so Hammer tought that I'm talking about the **** input, that ofcourse, it's not with fgets, he'll need getch() or getchar() or whatever, I was talking about scanf("%s",&password);

    That's it

    I see, we're getting a little mix up in our thoughts

    All standard input functions use buffered IO, fgets(), scanf(), getchar() etc etc.

    With regards to this:
    >>scanf("%s",&password)
    I would suggest that maybe password is already a char array, and therefore the code would look more like this:
    >>char password[100];
    >>scanf("%s",password);
    Note the & is not present as password is already a pointer being an array.

    But hey, I could be wrong, I've only got one line of code to go by..

    [edit]
    (I'm not promoting scanf(), btw, merely correcting the code in this thread. Check the FAQ for better ways to get strings from the user, if you don't know them already )
    When all else fails, read the instructions.

    Well hammer I have no idea
    Hmm, always when I ask the best way to get a string from a stream people tell me to use fgets()
