Language construct

Last updated

In computer programming, a language construct is "a syntactically allowable part of a program that may be formed from one or more lexical tokens in accordance with the rules of the programming language", as defined by in the ISO/IEC 2382 standard (ISO/IEC JTC 1). [1] A term is defined as a "linguistic construct in a conceptual schema language that refers to an entity". [1]

While the terms "language construct" and "control structure" are often used synonymously, there are additional types of logical constructs within a computer program, including variables, expressions, functions, or modules.

Control flow statements (such as conditionals, foreach loops, while loops, etc) are language constructs, not functions. So while(true) is a language construct, while add(10) is a function call.

Examples of language constructs

In PHP print is a language construct. [2]

<?phpprint'Hello world';?>

is the same as:

<?phpprint('Hello world');?>

In Java a class is written in this format:

publicclassMyClass{//Code . . . . . .}

In C++ a class is written in this format:

classMyCPlusPlusClass{//Code . . . .};
