 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
