The cin object provides the programming input
counterpart to the cout object.
Simplifying for the purposes of this course, let's say that
the cin object can be used to:
- Read data from the computer keyboard
- Deposit that data into variables that have been created
within the program.
For example, the boldface statement in
- Reads three values typed by the user at the keyboard,
(separated by space characters), and
- Deposits those values into the variables named first,
second, and third in that order.
