In computer science and computer programming, a data type (or simply type) is a classification identifying one of various types of data.
Contents
Description
Data type determines:
- The possible values for that type
- The operations that can be done on values of that type
- The meaning of the data
- The way values of that type can be stored
Type systems
Data types are used within type systems, which offer various ways of defining, implementing and using data types.
Type safety
Different type systems ensure varying degrees of type safety.
Programming language support
Almost all programming languages explicitly include the notion of data type, though different languages may use different terminology.
Common data types
Common data types include:
