In computing, object code or object module is the product of an assembler or compiler. [1] In a general sense object code is a sequence of statements or instructions in a computer language, [2] usually a machine code language (i.e., binary) or an intermediate language such as register transfer language (RTL). The term indicates that the code is ...
Object file. An object file is a file that contains machine code or bytecode, as well as other data and metadata, generated by a compiler or assembler from source code during the compilation or assembly process. The machine code that is generated is known as object code . The object code is usually relocatable, and not usually directly executable.
Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [ 1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ).
For example, an object can be a programming language variable, data structure, function, or method. In object-oriented programming (OOP), an object is an abstract data type with the addition of polymorphism and inheritance. An object-oriented system integrates code and data as objects that each have state (data) and behavior (code).
Executable and Linkable Format. An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections. In computing, the Executable and Linkable Format[ 2] ( ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared ...
In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object ( prototype-based inheritance) or class ( class-based inheritance ), retaining similar implementation. Also defined as deriving new classes ( sub classes) from existing ones such as super class or base class and then forming them into a ...
Objective-C derives its object syntax from Smalltalk. All of the syntax for non-object-oriented operations (including primitive variables, pre-processing, expressions, function declarations, and function calls) are identical to those of C, while the syntax for object-oriented features is an implementation of Smalltalk-style messaging.
Generic programming is about abstracting and classifying algorithms and data structures. It gets its inspiration from Knuth and not from type theory. Its goal is the incremental construction of systematic catalogs of useful, efficient and abstract algorithms and data structures. Such an undertaking is still a dream.
