return 0;
}
We can look at this code line by line.

The file we want to include is then specified inside the <> angle brackets. Here, we are including a file called iostream.h. This file handles the input and output of data to the console/screen.
On the second line, the // double slash marks the initiation of a code comment. Comments in code are not...
