Data abstraction, or abstract data types, is a programming methodology where one defines not only the data structure to be used, but the processes to manipulate the structure – like process abstraction, ADTs can be supported directly by programming languages ? To support it, there needs to be...
Abstract Data Type View -- What Described in a language-independent way Example: A Stack is a collection of data items where the last added item must be removed first (LIFO) Basic operations: Add an element to the container Remove an element from the container Check if an element is in t...

Common problems in writing an abstract Too long Too much detail Too short Failure to include important information Too long If your abstract is too long, it may be rejected - abstracts are entered on databases, and there are usually a specified maximum number of words. Abstracts are often too...

It can and should briefly state the problem, the method used to study the problem, and the principal data and conclusions. Often, the abstract supplants the need for reading the full paper; without such abstracts, scientists would not be able to keep up in active areas of research. This ...
