c# operator

+ 	Addition	Computes the sum of left and right operands.	int x = 5 + 5;

-	Subtraction	Subtract the right operand from the left operand	int x = 5 - 1;

*	Multiplication	Multiply left and right operand	int x = 5 * 1;

/	Division	Divides the left operand by the right operand	int x = 10 / 2;

&&	Computes the logical AND of its bool operands. Returns true both operands are true, otherwise returns false.	x && y;

||	Computes the logical OR of its bool operands. Returns true when any one operand is true.	x || y;

!	Reverses the bool result of bool expression. Returns false if result is true and returns true if result is false.	!false

%	Reminder	Computes the remainder after dividing its left operand by its right operand	int x = 5 % 2;

++	Unary increment	Unary increment ++ operator increases its operand by 1	x++
  
--	Unary decrement	Unary decrement -- operator decreases its operand by 1	x--
  
+	Unary plus	Returns the value of operand	+5
  
-	Unary minus	Computes the numeric negation of its operand.	-5

  =	Assignment	Assigns its right had value to its left-hand variable, property or indexer.	x = 10;

x op= y	Compound assignment	Short form of x =x op y where op = any arithmetic, Boolean logical, and bitwise operator.	x += 5;

??=	Null-coalescing assignment	C# 8 onwards, ??= assigns value of the right operand only if the left operand is null	x ??= 5;

//The or Symbol Is ||

//The AND Symbol is &
