ReferenceVariable Areferencevariableisanalias,thatis,anothernameforan alreadyexistingvariable/memoryinstance. Onceareferenceisinitializedwithavariable,eitherthevariable nameorthereferencenamemaybeusedtorefertothevariable. Thereferencevariableoncedefinedtorefertoavariablecan’t bechangedtopointtoothervariable.

DefiningReferenceVariable Referencevariablesaredefinedbyusing&symbolinthedefinition. Sincetheydonothaveanystorageoftheirownandarejust anothernameforthe existingstorage,theyneedtoinitializedbeforeusingthem. Fore.g. intx;

int&y=x.

TheexisitingmemoryXwillnowalsohaveanothernameY.

ReferenceVariableVSPointerVariable YoucannothaveNULLreferences.Youmustalwaysbeableto assumethatareferenceisconnectedtoalegitimatepieceof storage. Onceareferenceisinitializedtoanobject,itcannotbechangedto refertoanotherobject.Pointerscanbepointedtoanotherobjectat anytime. Areferencemustbeinitializedwhenitiscreated.Pointerscanbe initializedatanytime....
