Understanding pointers

Understanding pointers: Learning C
Understanding pointers: Learning C

A pointer is a variable that holds an address, such as the memory location of another variable. Pointers are declared like any variable, given a name and data type, but prefixed by using an asterisk. Pointers must be initialized before they're used, assigned the address of another variable or allocated chunk of memory. When used without an asterisk, a pointer variable references a memory location. When used with an asterisk, a pointer variable represents a value at its memory location.
