OPERATORS IN C# 2.0
Different types of operators are:
1. Arithmetic
2. Bitwise
3. Relational and logical
4. Assignment Operator
5. ? Operator
1. Arithmetic
Operator Meaning
+ Addition
- Subtraction
* Multiplication
/ Division
% Modulus
++ Increment
-- Decrement
The operators +, -, *, and / all work the same way in C# as they do in any other computer language (or in algebra, for that matter). These can be applied to any built-in numeric data type.
2. Bitwise
Operator Result
& Bitwise AND
| Bitwise OR
^ Bitwise XOR
>> Shift Right
<< Shift Left
~ One’s complement (unary NOT)
They perform Boolean logical operations.
3. Relational and logical
Relational operator produces true/false result .They often work with logical operator.
Operator Meaning
= = Equal to
!= Not equal to
> Greater than
< Less than
>= Greater than or equal to
<= Less than or equal to
The logical operators, the operands must be of type bool, and the result of a logical operation is of type bool.
Operator Meaning
& AND
| OR
^ XOR (exclusive OR)
|| Short-circuit OR
&& Short-circuit AND
! NOT
Here most of them came with a doubt that. What is the difference between & and && or | and ||.
int d=1,n=10;
if (d != 0 && (n % d) == 0)
Console.WriteLine(d + " is a factor of " + n);
/* Now, try the same thing without short-circuit operator.
This will cause a divide-by-zero error. */
d = 0; n = 10;
if (d != 0 & (n % d) == 0)
Console.WriteLine(d + " is a factor of " + n);
Implies
Implies is the new logical operator in C#. It works as follows:
p q p implies q
True True True
True False False
False False True
False True True
4. Assignment Operator
The assignment operator is the single equal sign, =.
Example : x=y=10;
5. ? Operator
This is also known as ternary operator.
Syntax:
Exp1? Exp2:Exp3
If the Exp1 is true it returns the value of Exp2.Else it returns the value of Exp3.
Sample code:
int i=1,j;
j = i > 0 ? 2 : 3; // j = 2 because i>0 is true
