Thread: using while(cin)

help, i've spent many a desperate compile trying to tweak this code to get it to run but can't get it to work. The code looks like this:

Code:

char letter;

while(cin)
{
cin>>letter;
// do some stuff
}

the purpose of the code is to pull in whatever the user types one character at a time and when they hit enter to process it. The problem is that when I try it and i hit enter it just moves the cursor down one line and waits.
