In computer science, primitive data types are a set of basic data types from which all other data types are constructed. [1] Specifically it often refers to the limited set of data representations in use by a particular processor , which all compiled programs must use.
This is a list of well-known data structures. For a wider list of terms, see list of terms relating to algorithms and data structures. For a comparison of running times for a subset of this list see comparison of data structures.
Data types may be categorized according to several factors: Primitive data types or built-in data types are types that are built-in to a language implementation. User-defined data types are non-primitive types. For example, Java's numeric types are primitive, while classes are user-defined.
A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b.In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need not be the case.
In computer science, a composite data type or compound data type is a data type that consists of programming language scalar data types and other composite types that may be heterogeneous and hierarchical in nature. It is sometimes called a structure or a record or by a language-specific keyword used to define one such as struct.
Object handling was completely rewritten for PHP 5, expanding the feature set and enhancing performance. [42] In previous versions of PHP, objects were handled like primitive types. [42] The drawback of this method was that the whole object was copied when a variable was assigned or passed as a parameter to a method.
all non-object types, including (e.g.) booleans and numbers: all object types, including (e.g.) arrays C++: all data types, except reference types, array types and function types: arrays and functions C# [5] all non-object types, including structures and enumerations as well as primitive types: all object-types, including both classes and ...
In C and C++, untagged unions are expressed nearly exactly like structures , except that each data member is located at the same memory address. The data members, as in structures, need not be primitive values, and in fact may be structures or even other unions.
