Chapter 6 – Exploring Conditional 
Program Flow

1. No. The purpose of an if()… else… statement is to provide a branch so that either one or the other branch of the statement will only be executed.
2. Not every instance of an if()… statement can be replaced with a switch()… statement because the conditional expression of an if()… statement can consist of multiple conditions resolving to a single Boolean value, whereas a switch()… statement generally tests for single values.
3. Yes, but it is sometimes awkward and less expressive than using a switch()… statement.
4. The best way to prevent the dangling else problem is to use brackets ({…}) for each branch of the if()… else… statement.
