I appreciate that anything that can be done by a switch statment, can be done by an if else statement.
But are there stylistic rules for when one should use the switch rather than if else statment.

Well,
switchfeels “lighter” in many cases than anif/else ifladder, in my opinion. Basically you don’t have that much syntax with braces and parentheses in the way of your code. That being said,switchinherits C’s syntax. That means you havebreakand only a single scope for variables unless you introduce new blocks.Still, the compiler is able to optimize
switchstatements into a lookup table and perform compile-time checking for literals when dealing with enumerations. So, I’d suggest that it’s usually preferable to useswitchoverif/else ifif you’re dealing with numeric or enum types.
