Operator
An operator may refer to any of the following:
1. In computer programming and at the command line, an operator is an object capable of manipulating a value or operator. For example, in "1 + 2", the "1" and "2" are the operands and the plus symbol is the operator. Below is a listing of common operators found in programming languages with explanations and examples.
| Operator | Alternative | Explanation | Examples |
|---|---|---|---|
| = | Equals (set a variable to a value). | a = b | |
| == | Eq or equ | Equals? (compare two values) | a == b |
| != | Ne or neq | Not equal | a != b |
| + | Plus | a + b | |
| += | Addition | a += b | |
| ++ | Increment | a++ | |
| - | Minus | a - b | |
| -= | Subtraction | a -= b | |
| -- | Decrement | a-- | |
| / | Divide | a / b | |
| * | Times | a * b | |
| > | Gt or gtr | Greater than | a > b |
| < | Lt or lss | Less than | a < b |
| >= | Ge or geq | Greater than or equal to | a >= b |
| <= | Le or leq | Less than or equal to | a <= b |
| <=> | Spaceship operator | ||
| || | or | Boolean or | a || b |
| && | and | Boolean and | a && b |
Booleans are also considered operators where AND, OR, and NOT can also be used in most programming languages.
