Operators
In mathematics, an operator is a symbol that represents a mathematical operation. There are several types of operators, including arithmetic, comparison, logical, and assignment operators.
Arithmetic Operators
Arithmetic operators are used to perform mathematical operations such as addition, subtraction, multiplication, division, and modulus (remainder).
- Addition:
+ - Subtraction:
- - Multiplication:
* - Division:
/ - Modulus:
%
Comparison Operators
Comparison operators are used to compare two values and return a Boolean result (true or false).
- Equal to:
== - Not equal to:
!= - Greater than:
> - Less than:
< - Greater than or equal to:
>= - Less than or equal to:
<=
Logical Operators
Logical operators are used to combine multiple conditions and return a Boolean result.
- AND:
&& - OR:
|| - NOT:
!
Assignment Operators
Assignment operators are used to assign values to variables.
- Assignment:
= - Addition assignment:
+= - Subtraction assignment:
-= - Multiplication assignment:
*= - Division assignment:
