Ordered List as Array

The list of integers could be placed into an array. In assembly language an array of integers is declared using the directive .word followed by a list of comma separated integers. Often the array is preceded by a word that holds the size of the array.

        .data
size:   .word  5
list:   .word  1,2,3,5,7

In practical programming a list of integers would probably be implemented as an array. Arrays have many advantages. But they also have disadvantages. Sometimes the nodes of the data structure come in several sizes, or the length of the list is highly variable. Then a linked list may be the best implementation.
