In computer programming, subprograms (functions) will "return" to the higher-level programs, which called them; return ends the current task. Wikibooks has more about this subject: Computer programming Computer programming (often simply programming) is the craft of implementing one or more interrelated abstract algorithms using a particular programming language to produce a concrete computer program. ...
In computer science, a subroutine (function, procedure, or subprogram) is a sequence of code which performs a specific task, as part of a larger program, and is grouped as one, or more, statement blocks; such code is sometimes collected into software libraries. ...
In common language, a task is part of a set of actions which accomplish a job; the sense is that useful work is getting done. Task analysis is the analysis or a breakdown of exactly how a task is accomplished, such as what sub-tasks are required. ...
In C++, return <X>; (where <X> is an expression) is a statement of code which tells a function to return the execution, of the program, to the calling function, and report the value of <X>. If the function does not have a return type (returns void), the return command can be used without a value to just break out of the current function and return to the calling one, as is the case in most versions of BASIC. C++ (pronounced see plus plus, IPA: /siË plÉ™s plÉ™s/) is a general-purpose computer programming language. ...
An expression in the very basic sense is the noun form of the verb express. ...
The term statement can have several meanings: In programming, a statement is an instruction to execute something that will not return a value. ...
Source code (commonly just source or code) is any series of statements written in some human-readable computer programming language. ...
BASIC is a family of high-level programming languages. ...
Certain programming languages, such as Perl and Ruby allow the programmer to omit an explicit return statement, specifying instead that the last evaluated expression is the return value of the subroutine. Values returned by the program when it terminates are often captured by Batch Programs. Perl, also Practical Extraction and Report Language (a backronym, see below), is an interpreted procedural programming language designed by Larry Wall. ...
Ruby is a reflective, object-oriented programming language. ...
Syntax
Return statements come in many shapes. The current syntaxes are most common:
As used in Java and C++: Java is a reflective, object-oriented programming language developed initially by James Gosling and colleagues at Sun Microsystems. ...
return value; As used in Smalltalk: Smalltalk is an object-oriented, dynamically typed, reflective, programming language designed at Xerox PARC by Alan Kay, Dan Ingalls, Ted Kaehler, Adele Goldberg, and others during the 1970s, influenced by Sketchpad and Simula-97. ...
^ value As used in Lisp: Lisp is a reflective, functional programming language family with a long history. ...
