Operator1. In computer programming and at the command line, an operator is an object that is 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
= Eq Equals a = b
== Eq Equals a == b
!= Ne 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 Greater than a > b
< Lt Less than a < b
>= Ge Greater than or equal to a >= b
<= Le Less than or equal to a <= b
|| 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.
