 Youcanaccessclusterelementsbyunbundlingthemallatonceorbyindexingoneatatime,
dependingonthefunctionyouchoose;eachmethodhasitsplace
 Unlikearrays,whichcanchangesizedynamically,clustershaveafixedsize,orafixednumberof
wiresinthem.
 Youcanconnectclusterterminalswithawireonlyiftheyhaveexactlythesametype;inother
words,bothclustersmusthavethesamenumberofelements,andcorrespondingelementsmust
matchinbothdatatypeandorder.
