Operator is a special symbol that tells the compiler to perform specific mathematical or logical Operation.

  • Arithmetic Operators
  • Relational Operators
  • Logical Operators
  • Bitwise Operators
  • Assignment Operators
  • Ternary or Conditional Operators

Arithmetic Operators

Given table shows all the Arithmetic operator supported by C Language. Lets suppose variable A hold 8 and B hold 3.

OperatorExample (int A=8, B=3)Result
+A+B11
-A-B5
*A*B24
/A/B2
%A%40

Relational Operators

Which can be used to check the Condition, it always return true or false. Lets suppose variable A hold 8 and B hold 3.

OperatorsExample (int A=8, B=3) Result
<A<BFalse
<=A<=10True
>A>BTrue
>=A<=BFalse
==A== BFalse
!=A!=(-4)True

Logical Operator

Which can be used to combine more than one Condition?. Suppose you want to combined two conditions A<B and B>C, then you need to use Logical Operator like (A<B) && (B>C). Here && is Logical Operator.

OperatorExample (int A=8, B=3, C=-10)Result
&&(A<B) && (B>C)False
||(B!=-C) || (A==B)True
!!(B<=-A)True

Truth table of Logical Operator

C1C2C1 && C2 C1 || C2!C1!C2
TTTTFF
TFFTFT
FTFTTF
FFFFTT

Assignment operators

Which can be used to assign a value to a variable. Lets suppose variable A hold 8 and B hold 3.

OperatorExample (int A=8, B=3)Result
+=A+=B or A=A+B11
-=A-=3 or A=A+35
*=A*=7 or A=A*756
/=A/=B or A=A/B2
%=A%=5 or A=A%53
=a=bValue of b will be assigned to a

Path variable is set for providing path for all Java tools like java, javac, javap, javah, jar, appletviewer which are used in java programming. All these tools are available in bin folders so we set path upto bin folders.

Classpath variable is set for providing a path for predefined Java classes which is used in our application. All classes are available in lib/rt.jar so we set classpath upto lib/rt.jar.

Cloud computing is the on demand availability of computer system resources, especially data storage and computing power, without direct active management by the user.
