This is related to a chapter from beautiful code. And in that chapter I read about the nested ifs.
The author was talking about deeply nested ifs as originator of bugs and less readable. And he was talking about replacing nested ifs with case statements and decision tables.
Can anybody illustrate how to remove nested ifs with case (select case) and decision tables ?
Well, not directly an answer to your question since you specifically ask about switch/case statements, but here is a similar question.
Invert “if” statement to reduce nesting
This talks about replacing nested if’s with guard-statements, that return early, instead of progressively checking more and more things before settling on a return value.
