								In a `switch`  statement you may not be able to specify all possible values as `case`  statements. Instead, you can add the `default`  statement which will be executed if no matching `case`  statements are found. Think of it like the final `else`  statement in an `if/else`  chain.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								A `default`  statement should be the last case.
