Syntactically valid part of a program formed from lexical tokens From Wikipedia, the free encyclopedia
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]
<?php
print 'Hello world';
?>
is the same as:
<?php
print('Hello world');
?>
In Java a class is written in this format:
public class MyClass {
//Code . . . . . .
}
In C++ a class is written in this format:
class MyCPlusPlusClass {
//Code . . . .
};
