Write a short note on pointer operators in c

Pointers (that is, pointer values) are generated with the ''address-of'' operator &, which we can also think of as the ''pointer-to'' operator. We demonstrate this by declaring (and initializing) an int variable i, and then setting ip to point to it:

 int i = 5;

ip = &i;

The assignment expression ip = &i; contains both parts of the ''two-step process'':&i generates a pointer to i, and the assignment operator assigns the new pointer to (that is, places it ''in'') the variable ip.
