Different Operators in C# Explained with Examples

Introduction: What are Operators in C#?

In C#, operators are special symbols or keywords that perform operations on operands like variables, constants, and expressions to produce a result.
They are essential for performing calculations, comparisons, logical evaluations, and more.

In this blog, we’ll explore different categories of operators in C# with simple examples!

1. Arithmetic Operators

Arithmetic operators are used to perform basic mathematical operations such as addition, subtraction, multiplication, and division.

List of Arithmetic Operators:

+ : Addition (adds two operands)
- : Subtraction (subtracts the second operand from the first)
* : Multiplication (multiplies two operands)
/ : Division (divides the first operand by the second)
% : Modulus (returns the remainder of division)

Example:

int a = 5;
int b = 3;
int sum = a + b;        // 8
int difference = a - b; // 2
int product = a * b;    // 15
int quotient = a / b;   // 1
int remainder = a % b;  // 2

2. Assignment Operators

Assignment operators are used to assign values to variables.

List of Assignment Operators:

= : Assigns the value of the right operand to the left operand.
+=, -=, *=, /=, %= : Compound assignment operators (perform an operation and assign the result).

Example:

int x = 10;
int y = 5;
x += y;   // x = x + y = 15

Assignment operators are great for simplifying expressions and updating variable values efficiently.

3. Comparison Operators

Comparison operators are used to compare two operands.
They return a boolean value (true or false) based on the comparison result.

List of Comparison Operators:

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

Example:

int p = 5;
int q = 3;
bool isEqual = p == q;         // false
bool isGreaterThan = p > q;    // true

These operators are essential in decision-making constructs like if, while, and for loops.

4. Logical Operators

Logical operators are used to perform logical operations, especially in control flow and conditional statements.

List of Logical Operators:

&& : Logical AND (returns true if both operands are true)
|| : Logical OR (returns true if at least one operand is true)
! : Logical NOT (reverses the logical state)

Example:

bool isTrue = true;
bool isFalse = false;
bool result = isTrue && isFalse;  // false

Logical operators are mainly used to combine multiple conditions.

5. Increment and Decrement Operators

Increment (++) and decrement (--) operators are used to increase or decrease the value of a variable by one.

Example:

int count = 0;
count++;   // count = 1
count--;   // count = 0

These are especially useful in loops and counters.

6. Conditional (Ternary) Operator

The conditional operator (? :) is a shorthand for if-else statements.
It evaluates a condition and returns one of two values based on the condition's result.

Syntax:

(condition) ? trueExpression : falseExpression;

Example:

int x = 5;
int y = (x > 0) ? 10 : -10;   // y = 10

The ternary operator helps simplify short conditional assignments.

Conclusion: Mastering Operators in C#

Operators in C# are fundamental building blocks that allow you to write expressive, clear, and powerful code.
By mastering different types of operators — arithmetic, assignment, comparison, logical, increment/decrement, and conditional — you’ll be able to perform operations efficiently and make better programming decisions.

Keep practicing these operators with different examples to deepen your understanding and become proficient in C# programming!
