to be short, i need a (way/code preferably a manipulator of i stream..)to input a password(string) form the user without echoing it on screen...no library functions has to be used e.g. getpass() of the nonstandard conio.h
plz..suggest yr ideas n ask me if any doubts.
I believe this is not possible.
i have asked the same qn. to many many people...but all hav replied it as "not possible".
all i want is to toggle echoing on and off the std ostream..if this is achieved then the problem is done...
i have an idea but right now dont know how to implement it..
first the standard output buffer is changed to a local buffer.
now the string is read..it would not get echoed on the screen(std o/p device as the buffer has been changed)..
now the standard buffer is restored..
This is platform dependent issue - you need to turn it off in a terminal/shell or using a system-dependent function.
Have you tried a google? But I think laserlight is correct in his assumption. There is no standard way to do that.
Oh and congrats on your new Mod positon laserlight! :)
Is there any other way to implement this...?
hey guys i tried it in google, comp.lang.c++ etc...all say there is no standard way...but guys i found this actually in Bjarne Stroustrup's book...so there is a way of achieving this...yet it is unknown..!
What exactly did Stroustrup say?Quote:

the actual question was to create two stream manipulators that toggles the echoing on and off.
Kindly provide the relevant quote from the book.Quote:

sorry i don remember the entire question.
its on the exercise section of this book.(at the end of chapter 21.Streams)

hey did any one find the answer?
Have you provided the exact quote yet?
We're still waiting for you to cite your references.
create a manipulator that turns character echoing on and off.
That's not a question, that's a demand. We don't do that here.
I'm closing this thread. If you have a question, feel free to create a new one.
i guess bjarne (the author) demands more....
