C# Operators

C# Operators types

1. Arithmetic Operators

• Addition (+)
  • Adds two operands
  • Example: int sum = a + b;
• Subtraction (-)
  • Subtracts second operand from the first
  • Example: int difference = a – b;
• Multiplication (*)
  • Multiplies two operands
  • Example: int product = a * b;
• Division (/)
  • Divides numerator by denominator
  • Example: int quotient = a / b;
• Modulus (%)
  • Returns remainder of division
  • Example: int remainder = a % b;

2. Comparison Operators

Equal to (==)

• Checks if two operands are equal
• Example: bool isEqual = a == b;

Not equal to (!=)

• Checks if two operands are not equal
• Example: bool isNotEqual = a != b;

Greater than (>)

• Checks if the left operand is greater than  the right
• Example: bool isGreater = a > b;

Less than (<)

• Checks if the left operand is less than the right
• Example: bool isLess = a < b;

Greater than or equal to (>=)

• Checks if the left operand is greater than or equal to the right
• Example: bool isGreaterOrEqual = a >= b;

Less than or equal to (<=)

• Checks if the left operand is less than or equal to the right
• Example: bool isLessOrEqual = a <= b;

3. Logical Operators

Logical AND (&&)

• Returns true if both operands are true
• Example: bool result = a && b;

Logical OR (||)

• Returns true if either operand is true
• Example: bool result = a || b;

Logical NOT (!)

• Reverses the logical state of its operand
• Example: bool result = !a;

4. Assignment Operators

Assignment (=)

• Assigns right operand to left operand
• Example: a = b;

Addition assignment (+=)

• Adds right operand to left operand and assigns the result to the left operand
• Example: a += b;

Subtraction assignment (-=)

• Subtracts right operand from left operand and assigns the result to the left operand
• Example: a -= b;

Multiplication assignment (*=)

• Multiplies left operand by right operand and assigns the result to the left operand
• Example: a *= b;

Division assignment (/=)

• Divides left operand by right operand and assigns the result to the left operand
• Example: a /= b;

Modulus assignment (%=)

• Calculates modulus using two operands and assigns the result to the left operand
• Example: a %= b;

5. Increment and Decrement Operators

• Increment (++)

• Increases an integer value by one
• Example: a++;

• Decrement (–)

• Decreases an integer value by one
• Example: a–;

6. Conditional Operator (Ternary Operator)

• Conditional (?:)

• Evaluates a boolean expression and returns the result of one of two expressions
• Example: string result = (a == b) ? “Equal” : “Not Equal”;
