The ternary operator can also be viewed as a binary map operation. In R—and other languages with literal expression tuples—one can simulate the ternary operator with something like the R expression c (expr1, expr2)[1 + condition] (this idiom is slightly more natural in languages with 0-origin subscripts).
In mathematics, a ternary operation is an n-ary operation with n = 3. A ternary operation on a set A takes any given three elements of A and combines them to form a single element of A . In computer science , a ternary operator is an operator that takes three arguments as input and returns one output.
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]
For n = 1 the median operator is just the unary identity operation x. For n = 3 the ternary median operator can be expressed using conjunction and disjunction as xy + yz + zx. For an arbitrary n there exists a monotone formula for majority of size O(n 5.3). This is proved using probabilistic method. Thus, this formula is non-constructive. [3]
the conditional operator can yield a L-value in C/C++ which can be assigned another value, but the vast majority of programmers consider this extremely poor style, if only because of the technique's obscurity. [6]

There are prefix unary operators, such as unary minus -x, and postfix unary operators, such as post-increment x++; and binary operations are infix, such as x + y or x = y. Infix operations of higher arity require additional symbols, such as the ternary operator ?: in C, written as a ? b : c – indeed, since this is the only common example, it ...
