Whats a switch statement and how is it run?
- The statement looks at a expression, such as a variable, and then evaluates each case to see if it fits the expression. Break makes it so that it does run to the next expression. Default is at the end for something that doesn't match anything.
- switch ($variable){
- case "condtion to match": '
- code to be executed if n=label1;
- break;
- default: code to be executed if n is different from both label1 and label2;}
