OPERATORS IN C++

Operators In C++:

Operators are symbols that perform operations on values and variables.

Operators in C++ can be classified into :

• Arithmetic Operator
• Relational Operator
• Logical Operator
• Bitwise Operator
• Assignment Operator

Arithmetic Operator:

This operator is used to perform arithmetic or mathematical operations on the operands.

+	Addition
-	Subtraction
*	Multiplication
/	Division
%	Modulus
++	Increment
--	Decrement

Program :

#include <iostream>
using namespace std;
int main() 
{
  int a = 40 + 60;
  cout << a;
  return 0;
}

Output :

100

Relational operator:

Relational operator is used to compare the operand. It is also known as comparison operator.The return value of a comparison is either 1 or 0, that is true (1) or false (0). These values are known as Boolean values.

==	Equal to	a == b
!=	Not equal	a != b
>	Greater than	a > b
<	Less than	a < b
>=	Greater than or equal to	a >= b
<=	Less than or equal to	a<= b

Program:

#include <iostream>
using namespace std;
int main() {
  int a = 5;
  int b = 3;
  cout << (a > b);
  return 0;
}

Output:

1

Logical operator :

Logical operator is used to determine the logic between operands.

&&	Logical and	It returns true if both statements are true  a < 3 && a < 5
||	Logical or	It returns true if one of the statements is true  a < 2 || a < 3
!	Logical not	It reverse the result and returns false if the result is true !(a < 5 && x < 8)

Bitwise operator:

• Bitwise operator is used on (binary) numbers.
• It perform operations on integer data at the individual bit.

&	AND	a & b
|	OR	a | b
^	XOR	a ^ b
<<	left shift	a<< 4
>>	right shift	a>>4

Assignment operator:

Assignment operator is used to assign values to variables.

=	a = 6
+=	a += 4
-=	a -= 4
*=	a *= 4
/=	a /= 4
%=	a %= 4
&=	a &= 4
|=	a |= 4
^=	a ^= 4
>>=	a >>= 4
<<=	a <<= 4

Program:

#include <iostream>

using namespace std;

int main() {

  int a = 20;

  a += 15;

  cout << a;

  return 0;

}

Output:

35
