Increment and decrement operators. Increment and decrement operators are unary operators that increase or decrease their operand by one. They are commonly found in imperative programming languages. C -like languages feature two versions (pre- and post-) of each operator with slightly different semantics. In languages syntactically derived from ...
C++ also contains the type conversion operators const_cast, static_cast, dynamic_cast, and reinterpret_cast. The formatting of these operators means that their precedence level is unimportant. Most of the operators available in C and C++ are also available in other C-family languages such as C#, D, Java, Perl, and PHP with the same precedence ...
Operator (profession), a professional designation used in various industries, e.g.: Switchboard operator, a occupation at a company offering telephone services. Heavy equipment operator, operates heavy equipment used in engineering and construction projects. Operator (military), a soldier in a special operations force.
Operator (mathematics) In mathematics, an operator is generally a mapping or function that acts on elements of a space to produce elements of another space (possibly and sometimes required to be the same space). There is no general definition of an operator, but the term is often used in place of function when the domain is a set of functions ...
Most programming languages support binary operators and a few unary operators, with a few supporting more operands, such as the ?: operator in C, which is ternary. 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.
Exclusive or, exclusive disjunction, exclusive alternation, logical non-equivalence, or logical inequality is a logical operator whose negation is the logical biconditional. With two inputs, XOR is true if and only if the inputs differ (one is true, one is false). With multiple inputs, XOR is true if and only if the number of true inputs is odd.
Operator theory. In mathematics, operator theory is the study of linear operators on function spaces, beginning with differential operators and integral operators. The operators may be presented abstractly by their characteristics, such as bounded linear operators or closed operators, and consideration may be given to nonlinear operators.
Null coalescing operator. The null coalescing operator is a binary operator that is part of the syntax for a basic conditional expression in several programming languages, such as (in alphabetical order): C# [ 1] since version 2.0, [ 2] Dart [ 3] since version 1.12.0, [ 4] PHP since version 7.0.0, [ 5] Perl since version 5.10 as logical defined ...
