Read a password from std::cin
I don't work normally with the console, so my question is maybe very easy to answer or impossible to do .
Is it possible to "decouple" cin
and cout
, so that what I type into the console doesn't appear directly in it again?
I need this for letting the user typing a password and neither me nor the user normally wants his password appearing in plaintext
on the screen.
I tried using std::cin.tie
on a stringstream
, but everything I type is still mirrored in the console.
