So what really is input? It is a stream or sequence of bytes that sends data into the main memory of a computer.

This can be through external devices or network connections!

This isn't quite C++ code. We'll get on to inputs in C++ very shortly. But for now can you see what we're doing. We're inputting data.

The text input is a sequence of bytes from our fingers, through our keyboards into the memory of our computers and the program!

We need to stream the string to cout.
