Explanation / Answer

void displayRecord(vector &items) {
int index;
cout<<"Enter the index of the item";
cin>> index;
Item e = items[index];
cout<<"description: " << description <<endl;
cout<<"quantity: " << quantity <<endl;
cout<<"wholesalecost: " << wholesalecost <<endl;
cout<<"retailcost: " << retailcost <<endl;
cout<<"date added: " << dateadded <<endl;
}
