C# - Operators and Expressions

Operators are used to process the data. Expressions are created by combining the operators with variables and constants.

For example:

int number1, number2, sum;
number1 = 10;
number2 = 20;
sum = number1 + number2;

 In the last statement, two variables using the + symbol. The + is a operator also there are many operators in c#.

Some mathematical operators used for mathematical calculations in programming:

Operator	Usage
+	Addition
-	Subtraction
/	Division
%	Percentage
*	Multiplication

There are some other frequently used operators, they are the logical operators. They can compare two values and give result in ‘true’ or ‘false’ they are mostly used to make decisions.

Some decision making statements:

Operators	Usage	Example
==	Equal	if(x==y)
&&	Checks for multiple conditions	if(x>y)&&(y>z)
>	Greater than	if(x>y)
<	Less than	if(x<y)
||	Checks for multiple conditions	if(x<y)||(y<x)
>=	Greater than or equal	if(x=>y)
<=	Less than or equal	if(x<=y)
!=	Not equal to	x != y
