EOF while scanning

hi. i wud like to scan the inputs until EOF ...how would i do that

On the assumption that "scan the inputs" means something, you would do ... whatever it is you intend to do ... until it fails. (Technically, it could fail for other reasons, like bad input, but you can check afterwards whether .eof is true.)

ignore the cases for bad input...i just need to identify end of input

untlii end of input

cin>>x;

should i do
while(.eof==true)
cin>>x;

let me have the code to do it

You need to read while the read is good. So while (cin >> x).

it doesnt work
fine do u know wat does rawinput()[-1] in python do...tat ll solve me the prob..
if yes i shud be able to do in c++

As a matter of fact, it (the while statement, I mean) does in fact work. You are typing EOF yourself with Ctrl-Z on Windows/Ctrl-D on *nix, yes? If you just want one line, that's something else. (Edit: You may have to press enter after EOF, of course, if you are typing this yourself.)
