how to input string as password.

[sriram]

hi everybody,

i need a way other than using library funcs to in put a string as
password in c++ directly thro the cin object. if any body finds it pl
tel me.

If you mean you want a way to control what gets echoed on the terminal
while you type, then the iostream library doesn't give you that level of
control.

yes i wanna off the echoing in c++ as done by the getpass() func in c.
n that 2 without a library function.i m sure there must b an answer
for this...

n yr prg wont run as it doesn't return any value as declared in int
main();

As far as I know what you want to do cannot be done in standard C++.

main();

Incorrect.

3.6.1/5:
A return statement in main has the effect of leaving the main
function (destroying any objects with automatic storage duration) and
calling exit with the return value as the argument. If control reaches
the end of main without encountering a return statement, the effect is
that of executing
return 0;

It doesn't have to!

i dont know what compiler u use but mine says...Function must return a

1. Yes, but since there is no support for these kinds of things in
standard C++ or in the standard library you'll either have to use a
library or write all the low-level terminal communication stuff
yourself (essentially rewriting the library).

2. Try to use whole words, it does not take that much extra time and
it make it easier to understand, especially for us non native English
speakers. Some people will not reply to posts not written in as proper
English as the poster can produce.

3. Try to remove signatures when replying to posts.

The compiler I use is not relevant. What is relevant is the paragraph
that I quoted from the C++ standard, which states quite clearly the
effect of control reaching the end of main without encountering a return
statement.

If your compiler does not behave that way, then it is not a C++ compiler
(despite what it might call itself).

Also, "void main()" is not now, nor has it ever been part of the C++
standard.

thanks for your concern.
i got struck with an idea but i don hav c++ here on this pc...
i am writing the code..

#include<iostream.h>
void main()
{
char pass[10];
cout<<"Password";
cout.flush();//flushin std ostream
cin.tie(0);//untie cin from cout so there wont be flushing of cout
implicitly
cin>>pass;
cout<<pass;
cout.flush();
}

try this..n tel whether it works or not.

Is that a warning? Implementations are allowed to issue any warnings
they want, regardless of whether the construct is valid code or not.
Many give a warning for this:
if (i = 1)
{
// do stuff
}
That's not because it's nonstandard code, but because it probably
represents a programmer error. Similarly missing return statements from
main() may mean the programmer forgot.

I know of no standard C++ way to do this. Anything you come up with will be
OS specific. If you don't need anything cross platform then try asking in a
newsgroup appropriate to your OS and maybe something could be come up with.

If there is no standard way, but program must be portable, make interface to
all target specific functions, so to port on concrete platform you will make
implementation of the interface.

//input with waiting, no echo
namespace Nwin95{void getch();}
namespace Nmsdos{void getch();}
namespace Nlinux{void getch();}
