A regular expression (sometimes abbreviated to "regex") is a pattern used to match character combinations in a string.
For example, a regular expression can be used to search for all text lines in a paragraph that contain word "red" and display those lines where the match is found.
The switch statement allows us to make a decision from the number of choices.
If a match is found to a case label, the program executes the associated statement.
If no match is found with any of the case statements, only the statements following the default are executed.
