to simplify operations on blocks of data and clarify data relationships. Structured data simplify parameter passing and reduce maintenance.The authors then discuss the benefits of using table look-ups instead of complicated conditional statements. The authors discuss three techniques to look up an entry in the table:
- Direct Access - The author discusses two ways, directly using data as a key to table and the other is fudging the table-lookup keys.
- Indexed Access - This works similar to handling of virtual memory address to physical memory address in operating systems.
- Stair-step Access - The entries in a table are valid for ranges of data. The authors also provide some suggestions on using the technique effectively.
(ADTs) such as:- Hide implementation details
- It's easier to improve performance
- Changes are localized
- The program becomes self-documenting
