An address-of operator is a mechanism within C++ that returns the memory address of a variable. These
addresses returned by the address-of operator are known as pointers, because they "point" to the
variable in memory.

The address-of operator is a unary operator represented by an ampersand (&). It is also known as an
address operator.

Address operators commonly serve two purposes:
1. To conduct parameter passing by reference, suchas by name

2. To establish pointer values. Address-of operators point to the location in the memory because
the value of the pointer is the memory address/location where the data item resides in
memory.
