Operators (programming)

performing order of mathematical operations

In mathematics, an operand is the object of a mathematical operation, i.e., it is the object or quantity that is operated on.

mathematical operation with only one operand

mathematical notation in which every operator follows all of its operands

mathematical notation in which every operator precedes all of its operands

computer operation that operates on values at the level of their individual bits

In computing and mathematics, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, the latter being called the modulus of the operation.

For example, the concatenation of "snow" and "ball" is "snowball". In certain formalizations of concatenation theory, also called string theory, string concatenation is a primitive notion.

construct used in computer programming, often associated to a mathematical operation

changing an expression from one data type to another

Mathematics notation with operators between operands

unary operators that add or subtract one from their operand, respectively

type of polymorphism in some programming languages where operators have different implementations depending on their arguments

built-in and (in C++) overloadable functions

ternary operator "x ? y : z" in many programming languages, whose value is y if x evaluates to true and z otherwise

programming language construct or operator that tests or defines some kind of relation between two entities

expression in a computer program that produces either "true" or "false" when evaluated

single computing operation which compares two values and returns their relative order

bit-level computer operation

binary operator that is part of the syntax for a basic conditional expression in several programming languages

property that determines how operators of the same precedence are grouped in the absence of parentheses

shift operator in computer programming

(C and C++ programming languages) binary operator that evaluates its first operand and discards the result, and then evaluates the second operand and returns this value (and type); represented by the token ,

overloadable collection indexing operator

unary operator

'''''' is a unary operator in the C and C++ programming languages that evaluates to the storage size of an expression or a data type, measured in units sized as char. Consequently, the expression sizeof(char) evaluates to 1. The number of bits of type char is specified by the preprocessor macro CHAR_BIT, defined in the standard include file limits.h|. On most modern computing platforms this is eight bits. The result of sizeof is an unsigned integer that is usually typed as .

binary operator in computer programming

a type of assignment operator where an operator takes a variable as one of its arguments and then assigns the result back to the same variable

', alternately also , and ', is an operator provided by several programming languages to determine the data type of a variable. This is useful when constructing programs that must accept multiple types of data without explicitly specifying the type.
