12. In C, explain the difference between the & operator and
the * operator.
& is the address operator, and it creates pointer values.
* is the indirection operator, and it dereferences pointers
to access the object pointed to.
Example:
In the following example, the pointer ip is assigned the
address of variable i (&i). After that assignment,
the expression *ip refers to the same object denoted by i:
int i, j, *ip;
ip = &i;
i = 22;
j = *ip; /* j now has the value 22 */
*ip = 17; /* i now has the value 17 */
