x=10
A>b&& x==10

7. ASSIGNMENT OPERATORS
Expr 1 = Expr 1 op Expr2
Expr1 op= Expr 2
sum = sum + i ;
sum += i ;
x = x * y + 1;
x *= y + 1;
x = x * (y+1)

8. INCREMENT & DECREMENT OPERATOR

Operator
++, -Prefix operator

n = 10;
x = ++n;
x= --n;

ans.11
ans. 9
Postfix operator
n = 20;
x = n++;
x=n--;
ans.20
ans.20

9. THE CONDITIONAL OPERATOR

Operator

Expr1 ? Expr2 : Expr3 (3 Terms Operator)
if (x > y) max = x;
else max = y;
max = x > y ? x : y ;

10. BITWISE OPERATOR
Operator
Meaning
&
And
|
Or
^
X or
<<
Left shift
>>
Right shift

11. SPECIAL OPERATOR

Size of operator

Example
#include <iostream.ha>
#include <conio.h>
Void main()
{
int a;
clrscr();
cout<<sizeof(a);
getch();
}

12. POINTER TO MEMBER OPERATOR
1): : *
to declare a pointer through of member of
class
2)* *
To express a member using object name to
the member
3)
’ To access a member using a pointer to the
object and a pointer to that member.

13. MEMORY MANAGEMENT
New
 Delete

Syntax
pointer variable=new data type[size]
Example
*p=new int[25]

14. SCOPE REZOULATION
#include<iostream.h>
#include<conio.h>
Void main()
{
int a=15;
main()
{
int a;
a=20;
cout<<“a:”<<a;
cout<<“::a”;<<:: a;
getch();
}
