C - Pointers4
- Since pointers are variables, they can be used without de-referencing.
- For example, if ip and iq are pointers to integers, then iq = ip, copies the contents of ip into iq, thus making iq point to whatever ip pointed to.
- Unary operators * and ++ associate right to left.
++*ip or (*ip)++; // increments what ip points *ip++; // increments the ip before de-referencing
