In .NET (especially C#), operators are symbols or keywords that perform operations on variables and values—things like arithmetic, comparison, and logic. Let’s break it down:

➕ Arithmetic Operators

• + : addition
• - : subtraction
• * : multiplication
• / : division
• % : modulus (remainder)

int result = 7 + 3;  // result is 10

⚖️ Comparison Operators

Used in conditions to compare values:

• == : equal to
• != : not equal to
• > : greater than
• < : less than
• >= : greater than or equal to
• <= : less than or equal to

bool isEqual = (5 == 5);  // true

🔄 Logical Operators

Great for combining Boolean expressions:

• && : logical AND
• || : logical OR
• ! : logical NOT

if (isSunny && isWarm) {
    Console.WriteLine("Perfect weather!");
}

🧠 Bitwise Operators

Operate at the binary level:

• & : AND
• | : OR
• ^ : XOR
• ~ : NOT
• << : left shift
• >> : right shift

🧩 Assignment Operators

Set and modify variable values:

• = : assign
• +=, -=, *=, /=, %= : shorthand for arithmetic + assignment

x += 5;  // same as x = x + 5

🧪 Other Notables

• ?? : null-coalescing operator

  string name = input ?? "Guest";
  

• ?. : null-conditional operator

  user?.SendEmail();  // only calls if user is not null
  

Operators in .NET help make your logic expressive, concise, and powerful.
