-A pointer can point to a typed object or to **`void`**. When a program allocates an object on the [heap](https://wikipedia.org/wiki/Heap) in memory, it receives the address of that object in the form of a pointer. Such pointers are called *owning pointers*. An owning pointer (or a copy of it) must be used to explicitly free the heap-allocated object when it's no longer needed. Failure to free the memory results in a *memory leak*, and renders that memory location unavailable to any other program on the machine. Memory allocated using **`new`** must be freed by using **`delete`** (or **`delete[]`**). For more information, see [`new` and `delete` operators](new-and-delete-operators.md).

-Certain arithmetic operations can be used on non-`const` pointers to make them point to another memory location. Pointers are incremented and decremented using the **`++`**, **`+=`**, **`-=`** and **`--`** operators. This technique can be used in arrays and is especially useful in buffers of untyped data. A `void*` gets incremented by the size of a **`char`** (1 byte). A typed pointer gets incremented by size of the type it points to.

 The following example demonstrates how pointer arithmetic can be used to access individual pixels in a bitmap on Windows. Note the use of **`new`** and **`delete`**, and the dereference operator.
