- Pointers store addresses of variables, allowing indirect access and manipulation.
- Use & (address-of) to get a pointer to an object.
- Use * (dereference/indirection) to access the object a pointer points to.
- Passing pointers to functions enables functions to modify the original variables.
- NULL pointer indicates a pointer that points to nothing, often used for error handling.
- Pointers are powerful but dangerous; they are essential for effective C programming.
