<code>switch</code> can contain a <code>default</code> clause for various reasons: to handle unexpected values, to show that all the cases were properly considered.
|
|
For readability purpose, to help a developer to quickly find the default behavior of a <code>switch</code> statement, it is recommended to put the <code>default</code> clause at the end of the <code>switch</code> statement. This rule raises an issue if the <code>default</code> clause is not the last one of the <code>switch</code>'s cases.
