Question:
Input and Output
Input and Output are necessary functions with any code.
Define I/O and identify some of the elements needed in C++ that would use input or create output.
Remember that input is not just from your keyboard and can be from a file or database.
Additionally, output isn't necessarily to a screen or a printer and can be to a file or a database.
If you can't think of any examples from the text or your own experiences, visit this Sample C++ Source Code website. You can use examples for any situation or device.
