The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
The concatenation operator is . (dot). Array elements are accessed and set with square brackets in both associative arrays and indexed arrays. Curly brackets can be used to access array elements, but not to assign. PHP has three types of comment syntax: /* */ which serves as block comments, and // as well as # which are used for inline comments ...
The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. The examples below make use of the ... The ternary operator can ...
PHP supports standard C/C++ style comments, but supports Perl style as well. Python The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [ 19 ]
In PHP, it is possible to leave out the middle part of the ternary operator since PHP 5.3. [8] (June 2009). The Fantom programming language has the ?: binary operator that compares its first operand with null. In Kotlin, the Elvis operator returns its left-hand side if it is not null, and its right-hand side otherwise. [9]
and | are bitwise operators that occur in many programming languages. The major difference is that bitwise operations operate on the individual bits of a binary numeral, whereas conditional operators operate on logical operations. Additionally, expressions before and after a bitwise operator are always evaluated.
OCaml expressions provide ternary operations against records, arrays, and strings: a.[b]<-c would mean the string a where index b has value c. [6] The multiply–accumulate operation is another ternary operator. Another example of a ternary operator is between, as used in SQL.
Many languages have an operator to accomplish the same purpose, generally referred to as a conditional operator (or, less precisely, as a ternary operator); the best known is ?:, as used in C, C++, and related languages. Some of the problems with the IIf function, as discussed later, do not exist with a conditional operator, because the ...
