Regular expressions are constructed analogously to arithmetic
expressions, by using various operators to combine smaller expressions.
-Note that the regular expression can be enclosed/delimited by either " or
-' which is useful if the regular expression includes a white-space

The fundamental building blocks are the regular expressions that match
a single character. Most characters, including all letters and digits,
