Summary: Multiway Decisions

This lesson summarizes the major points made in this chapter.

An if statement can contain other if statements. Together, such if statements are said to be nested.
When an else clause contains an if statement, it often is clearer to write the clause as an else if clause. Such a construct is a multiway if statement that provides several mutually exclusive choices.
In the absence of braces, an else clause is paired with the nearest preceding unmatched if.
A switch statement provides multiple courses of action according to the value of an expression whose data type is integer, character, enumerated, or String.
