Hi, I have the following problem:
I use "getch" to monitor keypresses and the I use "cin" to input a
string.
When I type in 'y', the 'y' character appears, so I need to hit backspace
before typing the string.
c = getch();
cin >> str;

Hi,
How do I read a char from stdin before the '\n' is pressed?
for example I know that I can use getch() to read a single char from the
user input, but suppose I wanted to read before the carriage return is
pressed.
for example I type a char and the following actions is done before the
'\n' is pressed.
