This task is about arrays.

For hashes or associative arrays, please see Creating an Associative Array.

For a definition and in-depth discussion of what an array is, see Array.



Task

Show basic array syntax in your language.

Basically, create an array, assign a value to it, and retrieve an element   (if available, show both fixed-length arrays and
dynamic arrays, pushing a value into it).

Please discuss at Village Pump:   Arrays.

Please merge code in from these obsolete tasks:

\\\\\\\\\\\\\\\\\\ Array implementation \\\\\\\\\\\\\\\\\\\\
 
A number array has a first element pointer.
 
A location is a number.
 
To create a number array given a count:
Put a number's magnitude times the count into a size.
Assign the number array's first element pointer given the size. \ allocate memory for the array
 
To destroy a number array:
Unassign the number array's first element pointer. \ free the array's memory
 
To get a number from a number array at a location:
Put the location times the number's magnitude into an offset.
Put the number array's first element pointer into a number pointer.
Add the offset to the number pointer.
Put the number pointer's target into the number.
 
To put a number into a number array at a location:
Put the location times the number's magnitude into an offset.
Put the number array's first element pointer into a number pointer.
Add the offset to the number pointer.
Put the number into the number pointer's target.
