Reading a password from std::cin

Question

I need to read a password from standard input and wanted std::cin not to echo the characters typed by the user...

How can I disable the echo from std::c

If you don't care about portability, you can use _getch() in VC.

#include 
#include 
#include 

int main()
{
    std::string password;
    char ch;
    const char ENTER = 13;

    std::cout << "enter the password: ";

    while((ch = _getch()) != ENTER)
    {
        password += ch;
        std::cout << '*';
    }
}

There is also getwch() for wide characters. My advice is that you use NCurse which is available in *nix systems also.
