There is two types of people, those who love pointers, and those who hate them.
Pro
- you can access anything in memory.
- passing a pointer is mush easier than passing the item itself.
- Pointers are faster as they are used at low level.

Con
- Memory leak and page fault.
- Heck of comfusing to understand.
- Seg. Fault part 2.
- Had to control as they can address to anywhere.
- Can cause other programs to seg. fault!
