 POINTER Definition
We define POINTER |
POINTER - (1) In programming, think of a pointer as an address. The address can point to just about anything, including another pointer. Ultimately, if you follow the trail of pointers you'll probably find some data--pointers are most often used to point to data. The purpose of pointers is so that when you are programming you can pass around a small address that points to some data, instead of passing the actual data around. (2) Pointers can also refer to the icon on the screen that you move around with a mouse or other pointing device. In a GUI environment you need a pointer to point to things so that you can select them. |
