  Operators

Arithmetic operator..

+	Adds two operands	A + B will give 30
-	Subtracts second operand from the first	A - B will give -10
*	Multiplies both operands	A * B will give 200
/	Divides numerator by de-numerator	B / A will give 2
%	Modulus Operator and remainder of after an integer division	B % A will give 0
++	Increment operator, increases integer value by one	A++ will give 11
--	Decrement operator, decreases integer value by one	A-- will give 9

Realtional operator…

Operator	Description	Example
==	Checks if the values of two operands are equal or not, if yes then condition becomes true.	(A == B) is not true.
!=	Checks if the values of two operands are equal or not, if values are not equal then condition becomes true.	(A != B) is true.
>	Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.	(A > B) is not true.
<	Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true.	(A < B) is true.
>=	Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.	(A >= B) is not true.
<=	Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.	(A <= B) is true.

Logical Operator….

Operator	Description	Example
&&	Called Logical AND operator. If both the operands are non-zero, then condition becomes true.	(A && B) is false.
||	Called Logical OR Operator. If any of the two operands is non-zero, then condition becomes true.	(A || B) is true.
!	Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true, then Logical NOT operator will make false.	!(A && B) is true.

Bitwise operator..

q	p & q	p | q	p ^ q
0	0	0	0	0
0	1	0	1	1
1	1	1	1	0
1	0	0	1	1

Jo right side py value hai wo p k lay hai (0 1 0 1)

Abe k program banty hai jes me arithmetic operator use hung y

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr() ; // use for clear output screen
int a,b,c ,d,e;
a=5+2;
b=5-1;
c=3*4;
d=5/2;
e=5%2;
cout<<” Addition of 5+2 is equal to =”<< a<<endl;
cout<<”subtraction of  5-1 is equal to =”<<b<<endl;
cout<<”Multiplaction of 3*4 is equal to =”<<c<<endl;
cout<<”division of 5/2 is equal to =”<<d<<endl;
cout<<”remendir of 5%2 is equal to =”<<e<<endl;
cout<<” Hacking And every Programming Logic”<<endl;
getch();
}

Ham ne int type k 5 variable liy ur us ko value de ab ham es ke value change nahe kar sakty es ka output kuch u ho ga ha ye endl newline par lany k lay use karty hai

Addition of 5+2 is equal to = 7
subtraction of  5-1 is equal to=4
Multiplaction of 3*4 is equal to =12
division of 5/2 is equal to =2
remendir of 5%2 is equal to= 1
Hacking And every Programming Logic

ye 5/2 wesy 2.5 ata hai par ham ne data type int use kia hoa float nahe es lay point wali value show nahe ho ge agr int k bajy float use karty to per ans.. 2.5 ata

Ap log khud se b koi program bana looo
Good luck
