Passing the istream& is as reference

#1

what exactly is meant by passing the istream by reference and what is “is”. sir said it is cin only but i dont understand how since it is passed by reference so how can we change the name from cin to is.

i am confused in distinguishing the terms of istream istream& is and cin… pls explain what they all mean seperately

hello @vector.9974

while passing object as reference we are allowed to change its name.

so u can write

returnType functionName( istream &anyNameThatUWantToGive){
// ur logic
}
