- A switch statement offers another way…to execute different code depending on a condition.…Before looking at real code, let's take a look…at the basic structure of a switch statement.…It consists of the keywords switch followed…by a pair of parentheses containing…the value you'd want to test.…The body of the switch statement goes between…a pair of curly braces.…Inside the braces, the case keyword precedes the value…that you wanted match…and the value is followed by a colon.…If the value pass to the switch statement matches,…any code that follows is executed.…
In effect, this is the same as a conditional statement…using if and testing whether var equals value1.…And on its own, it's a rather cumbersome approach.…But you can test for multiple values by adding break…at the end of each case and repeating the pattern.…At the end of the switch block,…you can add default followed by a colon…and any code that you want executed…if none of the values match,…Default has the same meaning as the else block…at the end of a conditional statement.…
