## C# Operators:

The following are the list of C# Operators:

- Basic Assignment Operator
- Arithmetic Operators
- Relational Operators
- Logical Operators
- Unary Operators
- Ternary Operator
- Bitwise and Bit Shift Operators
- Compound Assignment Operators

## 01. Basic Assignment Operator

The basic assignment operator (=) is used to assign a value to a variable. It takes the value on the right and stores it in the variable on the left.

### Example 1: Basic Assignment Operator

```
int x = 10;
int y = 20;
x = y;
Console.WriteLine(x); // Output: 20
```

### Table 1: Basic Assignment Operator

Name | Description | Example |
---|---|---|

= (Assignment) | Assigns the value on the right to the variable on the left. | int x = 10; |

*Assignment Operator*

## 02. Arithmetic Operators

Arithmetic operators perform mathematical operations such as addition, subtraction, multiplication, division, and modulus (remainder). The available arithmetic operators in C# are +, -, *, /, and % respectively.

### Example 2: Arithmetic Operators

```
using System;
class Program
{ //Example: Arithmetic operators in C#
static void Main()
{
int a = 10;
int b = 5;
// Addition operator
int sum = a + b;
Console.WriteLine($"Addition: {a} + {b} = {sum}");
// Subtraction operator
int difference = a - b;
Console.WriteLine($"Subtraction: {a} - {b} = {difference}");
// Multiplication operator
int product = a * b;
Console.WriteLine($"Multiplication: {a} * {b} = {product}");
// Division operator
int quotient = a / b;
Console.WriteLine($"Division: {a} / {b} = {quotient}");
// Modulus operator
int remainder = a % b;
Console.WriteLine($"Modulus: {a} % {b} = {remainder}");
Console.ReadLine();
}
}
```

**Output:**

```
Addition: 10 + 5 = 15
Subtraction: 10 - 5 = 5
Multiplication: 10 * 5 = 50
Division: 10 / 5 = 2
Modulus: 10 % 5 = 0
```

**Table 2: Arithmetic Operators**

Name | Description | Example |
---|---|---|

+ (Addition) | Adds two operands. | int result = x + y; |

– (Subtraction) | Subtracts the second operand from the first operand. | int result = x – y; |

* (Multiplication) | Multiplies two operands. | int result = x * y; |

/ (Division) | Divides the first operand by the second operand. | int result = x / y; |

% (Modulus) | Divides the first operand by the second operand and returns the remainder. | int result = x % y; |

*Arithmetic Operators*

## 03. Relational Operators

Relational operators are used to compare two values and return a Boolean result (true or false). The available relational operators in C# are ==, !=, >, <, >=, and <= respectively.

### Example 3: Relational Operators

```
using System;
class Program
{
static void Main()
{
int a = 10;
int b = 5;
// Greater than operator
bool greaterThan = a > b;
Console.WriteLine($"{a} > {b} = {greaterThan}");
// Less than operator
bool lessThan = a < b;
Console.WriteLine($"{a} < {b} = {lessThan}");
// Greater than or equal to operator
bool greaterThanOrEqualTo = a >= b;
Console.WriteLine($"{a} >= {b} = {greaterThanOrEqualTo}");
// Less than or equal to operator
bool lessThanOrEqualTo = a <= b;
Console.WriteLine($"{a} <= {b} = {lessThanOrEqualTo}");
// Equal to operator
bool equalTo = a == b;
Console.WriteLine($"{a} == {b} = {equalTo}");
// Not equal to operator
bool notEqualTo = a != b;
Console.WriteLine($"{a} != {b} = {notEqualTo}");
Console.ReadLine();
}
}
```

**Output:**

```
10 > 5 = True
10 < 5 = False
10 >= 5 = True
10 <= 5 = False
10 == 5 = False
10 != 5 = True
```

### Table 3: Relational Operators

Name | Description | Example |
---|---|---|

== (Equal to) | Returns true if the operands are equal. | bool result = x == y; |

!= (Not equal to) | Returns true if the operands are not equal. | bool result = x != y; |

> (Greater than) | Returns true if the first operand is greater than the second operand. | bool result = x > y; |

< (Less than) | Returns true if the first operand is less than the second operand. | bool result = x < y; |

>= (Greater than or equal to) | Returns true if the first operand is greater than or equal to the second operand. | bool result = x >= y; |

<= (Less than or equal to) | Returns true if the first operand is less than or equal to the second operand. | bool result = x <= y; |

*Relational Operators*

## 04. Logical Operators

Logical operators are used to perform logical operations on Boolean values. The available logical operators in C# are && (logical AND), || (logical OR), and ! (logical NOT), respectively.

### Example 4: Logical Operators

```
using System;
class Program
{
static void Main()
{
bool a = true;
bool b = false;
// Logical AND operator
bool andResult = a && b;
Console.WriteLine($"{a} && {b} = {andResult}");
// Logical OR operator
bool orResult = a || b;
Console.WriteLine($"{a} || {b} = {orResult}");
// Logical NOT operator
bool notResult = !a;
Console.WriteLine($"!{a} = {notResult}");
Console.ReadLine();
}
}
```

**Output:**

```
True && False = False
True || False = True
!True = False
```

### Table 4: Logical Operators

Name | Description | Example |
---|---|---|

&& (Logical AND) | Returns true if both operands are true. | bool result = x && y; |

|| (Logical OR) | Returns true if either operand is true. | bool result = x || y; |

! (Logical NOT) | Returns true if the operand is false and vice versa. | bool result = !(x == y); |

*Logical Operators*

## 05. **Unary Operators**

Unary operators are used to perform operations on a single operand. The available unary operators in C# are ++ (increment), — (decrement),! (logical NOT), and ~ (bitwise NOT), respectively.

### Example 5: Unary Operators

```
using System;
class Program
{
static void Main()
{
int a = 5;
// Unary plus operator
int unaryPlus = +a;
Console.WriteLine($"+{a} = {unaryPlus}");
// Unary minus operator
int unaryMinus = -a;
Console.WriteLine($"-{a} = {unaryMinus}");
// Increment operator
int preIncrement = ++a;
Console.WriteLine($"++{a} = {preIncrement}");
int postIncrement = a++;
Console.WriteLine($"{a}++ = {postIncrement}");
// Decrement operator
int preDecrement = --a;
Console.WriteLine($"--{a} = {preDecrement}");
int postDecrement = a--;
Console.WriteLine($"{a}-- = {postDecrement}");
Console.ReadLine();
}
}
```

**Output:**

```
+5 = 5
-5 = -5
++6 = 6
7++ = 6
--6 = 6
5-- = 6
```

### Table 5: Unary Operators

Name | Description | Example |
---|---|---|

++ (Increment) | Adds 1 to the operand. | x++; or ++x; |

— (Decrement) | Subtracts 1 from the operand. | x–; or –x; |

+ (Unary plus) | Indicates a positive value. | int result = +x; |

– (Unary minus) | Indicates a negative value. | bool result = -x; |

! (Logical NOT) | Inverts the value of a Boolean expression. | bool result = !x; |

~ (Bitwise NOT) | Inverts the bits of an integer. | int result = ~x; |

*Unary Operators*

## 06. Ternary Operator

The ternary operator `?: `

is a shorthand way of writing an if-else statement. It takes three operands: the condition to evaluate, the expression to return if the condition is true, and the expression to return if the condition is false.

### Example 6: Ternary Operator

```
using System;
class Program
{
static void Main()
{
int a = 5;
int b = 10;
// Ternary operator
int max = (a > b) ? a : b;
Console.WriteLine($"Max value: {max}");
// Nested ternary operator
int c = 15;
int min = (a < b) ? ((a < c) ? a : c) : ((b < c) ? b : c);
Console.WriteLine($"Min value: {min}");
}
}
```

**Output:**

```
Max value: 10
Min value: 5
```

### Table 6: Ternary Operator

Name | Description | Example |
---|---|---|

Ternary | A conditional operator that takes three operands and returns one of two values based on the condition. | Condition? trueValue: falseValue |

True Condition | The Condition is true and returns a true value. | int a = 10; int b = 5; int max = (a > b) ? a : b; |

False Condition | The Condition is false and returns a false value. | int a = 10; int b = 5; int min = (a < b) ? a : b; |

*Ternary Operator*

## 07. Bitwise and Bit Shift Operators

Bitwise and bit shift operators are used to perform operations on the individual bits of an operand. The available bitwise and bit shift operators in C# are & (bitwise AND), | (bitwise OR), ^ (bitwise XOR), << (left shift), and >> (right shift), respectively.

### Example 7: Bitwise and Bit Shift Operator

```
using System;
class Program
{
static void Main()
{
int a = 5; // binary 0000 0101
int b = 10; // binary 0000 1010
// Bitwise AND operator
int bitwiseAnd = a & b; // binary 0000 0000 = 0
Console.WriteLine($"Bitwise AND: {bitwiseAnd}");
// Bitwise OR operator
int bitwiseOr = a | b; // binary 0000 1111 = 15
Console.WriteLine($"Bitwise OR: {bitwiseOr}");
// Bitwise XOR operator
int bitwiseXor = a ^ b; // binary 0000 1111 = 15
Console.WriteLine($"Bitwise XOR: {bitwiseXor}");
// Bitwise complement operator
int bitwiseComplement = ~a; // binary 1111 1010 = -6
Console.WriteLine($"Bitwise Complement: {bitwiseComplement}");
// Left shift operator
int leftShift = a << 2; // binary 0001 0100 = 20
Console.WriteLine($"Left Shift: {leftShift}");
// Right shift operator
int rightShift = b >> 2; // binary 0000 0010 = 2
Console.WriteLine($"Right Shift: {rightShift}");
}
}
```

**Output:**

```
Bitwise AND: 0
Bitwise OR: 15
Bitwise XOR: 15
Bitwise Complement: -6
Left Shift: 20
Right Shift: 2
```

### Table 7: Bitwise and Bit Shift Operators

Name | Description | Example |
---|---|---|

& (Bitwise AND) | Compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if both bits are 1; otherwise, 0. | int result = x & y; |

| (Bitwise OR) | Compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if either bit is 1; otherwise, 0. | int result = x | y; |

^ (Bitwise XOR) | Compares each bit of the first operand to the corresponding bit of the second operand and returns 1 if the bits are different; otherwise, 0. | int result = x ^ y; |

<< (Left shift) | Shifts the bits of the first operand to the left by the number of positions specified by the second operand. | int result = x << y; |

>> (Right shift) | Shifts the bits of the first operand to the right by the number of positions specified by the second operand. | int result = x >> y; |

*Bitwise and Bit Shift Operators*

## 08. Compound Assignment Operators

Compound assignment operators combine a binary operation with an assignment operation. The available compound assignment operators in C# are +=, -=, *=, /=, %=, &=, |=, ^=, <<=, and >>= respectively.

### Example 8: Compound Assignment Operator

```
using System;
class Program
{
static void Main()
{
int a = 5;
// Addition assignment operator
a += 2; // equivalent to a = a + 2
Console.WriteLine($"Addition: {a}");
// Subtraction assignment operator
a -= 3; // equivalent to a = a - 3
Console.WriteLine($"Subtraction: {a}");
// Multiplication assignment operator
a *= 4; // equivalent to a = a * 4
Console.WriteLine($"Multiplication: {a}");
// Division assignment operator
a /= 2; // equivalent to a = a / 2
Console.WriteLine($"Division: {a}");
// Modulus assignment operator
a %= 3; // equivalent to a = a % 3
Console.WriteLine($"Modulus: {a}");
// Bitwise AND assignment operator
a &= 1; // equivalent to a = a & 1
Console.WriteLine($"Bitwise AND: {a}");
// Bitwise OR assignment operator
a |= 2; // equivalent to a = a | 2
Console.WriteLine($"Bitwise OR: {a}");
// Bitwise XOR assignment operator
a ^= 3; // equivalent to a = a ^ 3

}
}
```

**Output:**

```
Addition: 7
Subtraction: 4
Multiplication: 16
Division: 8
Modulus: 2
Bitwise AND: 0
