Dereferencing
refers to accessing the value that a pointer
points to.
To do this
“*” operator that interprets single argument
as an address and returns the contents of
the address as the value of the operation.
Usage:
n*p
EXAMPLE:
nint i = 25, *j;
nHere, j is a pointer to integer. Assume i and j are allocated memory cells at addresses 5FA62 and 5FA70, respectively. This means that the value of i is 25, &i is 5FA62 and the value of &j is
5FA70.
