CPointer

(C) Pointer

A pointer is a type that holds an address.

When a pointer is uninitialized, it should point to 0 or NULL.

You initialize a pointer using the function malloc, which reserves free space for the dynamically allocated  ?instance and returns the address to it.

C does not free this memory on its own. Therefore, you have to call  ?free to do so.

Reading/writing from/to an uninitialized pointer results in an  ?access violation.
