What you will learn here about operators.
- Addition ( + )
- Subtraction ( – )
- Multiplication ( * )
- Division( / )
- Modulo Division ( % )
- Increment ( ++ )
- Decrement ( -- )
1)Addition ( + )
Addition operator used to add two number together.
var num=num1+num2; //result is 150
Incase of String, Addition operator acts as concatenation operator.
var num=”Jon”+” Dow”; //result is “Jon Dow”
Number + String always gives String result but first addition is performed; Example is given below
var num=100+50+” Jon Dow”; //result is “150 Jon Dow”
String + number always gives String result. Example is given below.
var num=”Jon Dow “+100+50; //result is “Jon Dow 10050”
2)Subtraction ( – )
The Subtraction(-) operator is used subtract one number from another number.
var num=num1-num2; //result is 50
3)Multiplication ( * )
The Multiplication operator is used to multipy two numbers.
var num=num1*num2; //result is 5000
4)Division( / )
The Division operator is used to performe division between two numbers and returns the quotient of the division.
var num=num1/num2; //result is 2
5)Modulo Division ( % )
The Modulo Division operator is used to perform division between two numbers and returns the remainder of the division.
var num=num1%num2; //result is 0
6)Increment ( ++ )
Increment operator is used to increment number by 1. i++ is the post increment which first returns value then increment by value 1. ++i is the pre increment which first increment value by 1 and then returns the value.
++i; //Pre increment
7)Decrement ( -- )
Decrement operator is used to decrement number by 1. i-- is the post decrement which first returns value then decrement by value 1. --i is the pre increment which first decrement value by 1 and then returns the value.
--i; //pre decrement
