alias for a variable
What does it mean that &n is an alias for n?
thanks in advance!
An alias is another name for the exact same thing. I suspect this is really a question about references.
int n; // an int variable
int& p = n; // p is a reference to n. p is not a separate int. It is
// another name for the exact same object - an alias.
It is not. &n gives a pointer to n; it is the address of n.
