Password Asterisks

I am writing a Visual C++ program that executes from the command line that requires the user to input a password. How do I get the password to show up as asterisks instead of plain text as the user is typing it in?

read the threads on the faq board. and/or search these boards for password or similar because we have done this loads of times.

Code:

---

#include "stdio.h"
#include "conio.h"

#define TRUE  1
#define ENTER  0x0D  // Enter Key
int main()
{
        // Yeah, yeah, i know = { NULL } isn't good to use
        char str[80] = { NULL };
        int  idx = 0;
        printf("\n\n Type your life away\n ---");
        printf("\n Input [hidden] : ");

        while(TRUE)
        {
                char ch = getch();

                if(ch == ENTER)
                        break;
                else
                        putchar('*');

                str[idx] = ch; idx++;
        }
       
        printf("\n You entered    : %s\n\n", str);

        return 0;
}
