X-no-archive: yes
Newbie C++ programmer reads the following statement from the C++
'Deitel & Deitel' textbook:
"Reference variables can be used as local aliases within a function.
They must be initialized upon declaration, and cannot be reassigned to
other variables thereafter. All operations supposedly performed on the
alias is actually performed on the variable."
So my question is... what the heck is the point of using a reference
variables as an alias? It seems so much simpler to use the variable
itself instead of using an alias. I don't get it.
