if u use windows and u have conio library try getpass , it wont show the pass, if u want to make ur own function (still if u use windows) try getch, it will get the ASCII and wont echo on screen then u can echo * and reinterpret the ASCII, of course maybe there are better ways to do it. On *nix i dont know sry

Just iterate through all 'pass' characters using a for loop, and replace every char with a '*'. Example: a[1] = '*', a[2] = '*' .... a[i] = '*'. It's very simple ...

Use getch() and if you want to make it so you can hit enter to end it you will need to have it ignored(its character 13 if you are wondering).

heh.. In the Borland Turbo C++ book there's a getche() that may work, get character and echo... But I have done it with getch() and checking for the integer value of 13 in the ascii character. on the visual studio 2010 beta 2 it looks like getche() doesn't have any options for what character to output when it nabs one.


When the user is typing the password I don't think it will show on the screen. That's probably what he/she wants. getch()


puts() is also in there, it lets you type a string and adds the \n to the end...

You'll need to have it cout the stars after the getch manually.

I have successfully made such a function which prints Asteriks instead of any input. Backspaces are also handled. In any case as per the rules of dreamincode I cannot hand you the code but I can guide you how I did it:

The basic algo was:

I took an array and put in a password to compare

Then asked the user to enter a password

from the conio.h library you can use the getch() function to take input without the input showing on the output screen.

You can store that input in a temporary variable

Then check to see what that input is

There is another library cctype you can use to check if the entered input is a digit or whatever you can check that here:
http://www.cplusplus...library/cctype/

And well then you can use a couple of if conditions to print whatever you wish a * or & or whatever

Try figuring out the algo for backspaces if you do not get it let me know.

I do actually believe there will be a snippet on it shortly, hopefully.
