Fundamental Data Types

Input and Output

>> operator reads console input:

cin >> pennies;
If user doesn't enter appropriate input, then the stream fails. All subsequent input also fails.
Can read multiple values:

cin >> pennies >> nickels >> dimes >> quarters;
User enters input separated by spaces or newlines, e.g.

8 0 4 3

or
```
8
0
4
3
```
Input is buffered. If you type two inputs on one line, the second one is saved for the next input statement.
