# C# Operators

C# operators commonly used can be defined as 3 categories:
• Arithmetic
• Relational
• Logical

## Arithmetic Operators

Operator Description
+ (Addition) returns the sum of the operands
- (Substraction) returns the difference of the values
* (Multiplication) returns the product of the values
/ (Division) performs division operation and returns the quotient
% (Modulo) performs division operation and returns the remainder

### C# Example of Arithmetic Operators

``````using System;

namespace MyApplication
{
class Program
{
static void Main(string[] args)
{
int x = 10;
x += 5;
Console.WriteLine(x);
}
}
}``````

15

## Relational Operators

Operator Description
> Greater than
< Lesser than
>= Greater than or equal to
<= Lesser than or equal to
== is Equal
!= is not Equal

### C# Example of Relational Operators

``````using System;

namespace MyApplication
{
class Program
{
static void Main(string[] args)
{
int x = 10;
Console.WriteLine(x==10);
}
}
}``````

True

## Logical Operators

Operator Description
&& (And)  The operator returns true only if all the expressions specified return true
||(OR)  The operator returns true if at least one of the expressions specified return true
! (NOT) The operator returns the inverse of the expressionâ€™s result. For E.g.: !(>5) returns false

### C# Example of Logical Operators

``````using System;

namespace MyApplication
{
class Program
{
static void Main(string[] args)
{
int x = 10;
Console.WriteLine(x==10 && x >20 );
}
}
}``````

False
