Hiding user input

[raydona]

I am writing a program, console not Windows application, where a password has to be entered and then confirmed. I do not want the user's password to be displayed while it is being entered. In other words when the user enters the character, say, R I wish X to be shown on the screen. How can I go about coding this? I would be very grateful for all help.

I don't believe there is a standard or platform-independent way to do this. You might want to look into using getch if that exists on your platform. Here is an example that works with VC++ 7.1:

#include <iostream>
#include <string>
#include <conio.h>

int main()
{
    std::cout << "Enter password: " << std::flush;
    int c = 0;
    std::string password;
    while (true)
    {
        c = getch();
        if (c == '\r')
        {
            std::cout << std::endl;
            break;
        }

        password += static_cast<char>(c);
        std::cout << '*' << std::flush;
    }
    std::cout << "Your password is: " << password << std::endl;
}
