 Objects (such as values of variables) are stored at a specific location in the computer's memory.  These locations are called memory addresses.  Pointers are variables that store the location of a specific memory address.  They are primarily used to to access arrays and create data structures.
 
 
 

• Introduction to Pointers

• Declaring a Pointer

• int object;
• int *object_ptr;

 
• Pointer Operators

• * Dereference -- given a pointer, obtain the object referenced
• & Address of -- given an object, get its address
• thing -- a variable
• &thing -- pointer to the variable thing, i.e. the address of where "thing" is stored
• thing_ptr -- a pointer to the location at which the value of variable "thing" is stored
• *thing_ptr -- the "thing" variable

• Arrays and Pointers

• working with pointers and arrays -- syntax

• Examples

• thing.c
• pointer_array.c
