Understanding pointers: C: Data Structures, Pointers, and File Systems

A pointer is a variable that holds a memory location, the address of another declared variable in a program. Pointers are declared as variables, but with the asterisk operator prefix. Pointers are used in two ways: without the asterisk, the pointer represents an address, with an asterisk, a pointer represents the value stored at its address. The ampersand operator is used to obtain the address of a variable. Always initialize pointers before you use them.
