Operator
|
Use
|
Description
|
+
|
op1 + op2
|
Adds op1 and op2
|
*
|
op1 * op2
|
Multiplies op1 by op2
|
/
|
op1 / op2
|
Divides op1 by op2
|
%
|
op1 % op2
|
Computes the remainder of dividing op1 by op2
|
-
|
op1 – op2
|
Subtracts op2 from op1
|
Operator Increment dan Decrement
Operator
|
Use
|
Description
|
++
|
op++
|
Increments op by 1; evaluates to the value of op before it was
incremented
|
++
|
++op
|
Increments op by 1’ evaluates to the value of op before it was
decremented
|
--
|
op--
|
Decrements op by 1; evaluates to the value of op before it was
decremented
|
--
|
--op
|
Decrements op by 1; evaluates to the value of op after it was
decremented
|
Operator Relasi
Operator relational digunakan
untuk membandingkan beberapa nilai dan
menuntaskan hubungan antara nilai-nilai tersebut
Output dari perbandingan tersebut
adalah nilai Boolean antara true atau false
Operator
|
Use
|
Description
|
>
|
op1 > op2
|
Op1 is greater than op2
|
>=
|
op1 >= op2
|
Op1 is greater than or equal to op2
|
<
|
op1 < op2
|
Op1 is less than op2
|
<=
|
op1<= op2
|
Op1 is less than or equel to op2
|
==
|
op1== op2
|
Op1 and op2 are equal
|
!=
|
op1!= op2
|
Op1 and op2 are not equal
|
