Given that iptr is a pointer variable, the chunk of memory allocated
for iptr contains the address of a chunk of memory allocated for an
integer.
Thereafter, iptr, without an asterisk, refers to the location of an
address; *iptr, with an asterisk, refers to the location of the
integer identified by the address:
iptr refers to the address of the byte where a
pointer to an integer object begins; here, the
value of iptr is 88, an address
