EtymologyFrom the perfect passive participle stem of concatenare ‘chain together’, from con- ‘with’ + catenare ‘to chain’, from catena ‘chain’.
- To join or link together, as though in a chain.
- 2003: Locke, by contrast, contended that [madness] was essentially a question of intellectual delusion, the capture of the mind by false ideas concatenated into a logical system of unreality. — Roy Porter, Flesh in the Age of Reason (Penguin 2004, p. 182)
- Form of Second-person plural imperative, concatenare#Italian|concatenare
In computer programming, concatenation is the operation of joining two character strings end to end. For example, the strings "foo" and "bar" may be concatenated to give "foobar". In programming languages, string concatenation is a binary operation usually accomplished by putting a concatenation operator between two strings (operands).
For example, the following expression uses the "+" symbol as the concatenation operator:
print "Hello " + "World";
which produces the output:
Different languages use different operators. Most languages use the "+" sign though several deviate from this norm.
For a more detailed comparison, please see the concatenation comparison article.
For example, in PHP and Perl:
//Example 1 (concatenation operator ".") $var = "Hello "; $var = $var . "World";
//Example 2 (combined assignment and concatenation ".=") $var = "Hello "; $var .= "World";
Both examples produce the same result.
InterpolationSome languages, (such as Perl, PHP, and most Unix shells), support variable interpolation as an alternative form of string concatenation.
For example, in Perl, the concatenation syntax:
my $stringVar; $stringVar = "World"; print "Hello " . $stringVar;
can be substituted with the string literal syntax:
my $stringVar; $stringVar = "World"; print "Hello $stringVar";
