NOTE CHAPTER4.
OPERATORS AND EXPRESSION.


1. OPERATORS IN C++ PROGRAMMING LANGUAGE.


a)ARITHMETIC OPERATORS.
+-->addition.
_ --> subtraction.
* -->multiplication.
/ -->devision.
% -->modulus.


2.RELATIONAL OPERATORS.
> : greater than.
< : less than.
>= :greater than and equal.
=< :less than and equal.
== :equal.


3.LOGICAL OPERATOR.
&& :and.
! :not.
|| :or.


4.INCIMENT AND DECREAMENT.


INCEMENT=A)Pre-inciment(++n)
                      B)Post-incimeny(n++)


DECREMENT=A)Pre-decrement(--n)
                        B)Post-decrement(n--)


5.CONTOH SOALAN.


a)int n;
    n=5;


   cout<<n;5
   cout<<++n;1+5
   cout<<n;6


b)int m;
   m=10;
   cout<<m;10
   cout<<m--;10
   cout m;9
