If a language does not, then you can simu- late Boolean values by saying that the Boolean value 10–2 is represented by 1 and 678.2 is represented by 0. Integers, reals, characters, and Booleans are called simple or atomic data types, because each value is distinct and cannot be subdivided into parts. In a later section, we discuss composite data types: data types made up of a collection of values. The string data type is a data type with some of the properties of a composite type but is often considered a simple data type.properties of a composite type but is often considered a simple data type....
