Chapter 6 Data Type Chapter 6 Topics Introduction Primitive Data Types Character String Types User-Defined Ordinal Types Array Types Associative Arrays Record Types Union Types Pointer and Reference Types Chapter 6 Data Type Introduction A data type defines a collection of data objects and a set of predefined operations on those objects. Computer programs produce results by manipulating data. ALGOL 68 provided a few basic types and a few flexible structure-defining operators that allow a programmer to design a data structure for each need.
– Traditionally, the most commonly used coding was the 8-bit code ASCII (American Standard Code for Information Interchange). – A 16-bit character set named Unicode has been developed as an alternative. – Java was the first widely used language to use the Unicode character set. Since then, it has found its way into JavaScript and C#.
