C sharp - Relational and Assignment Operators

1. Relational Operators

Definition:

Relational operators are used to compare two values. They return a boolean result (true or false).

List of Relational Operators in C#:

Operator Description Example Result
== Equal to 5 == 5 true
!= Not equal to 5 != 3 true
> Greater than 10 > 8 true
< Less than 4 < 7 true
>= Greater than or equal to 6 >= 6 true
<= Less than or equal to 2 <= 3 true

Example:

int a = 10;
int b = 20;

Console.WriteLine(a == b); // false
Console.WriteLine(a != b); // true
Console.WriteLine(a < b);  // true

2. Assignment Operators

Definition:

Assignment operators are used to assign values to variables.

 List of Assignment Operators in C#:

Operator Description Example Equivalent To
= Assign a = 5  
+= Add and assign a += 3 a = a + 3
-= Subtract and assign a -= 2 a = a - 2
*= Multiply and assign a *= 4 a = a * 4
/= Divide and assign a /= 2 a = a / 2
%= Modulus and assign a %= 3 a = a % 3

Example:

int x = 10;

x += 5;  // x = x + 5 => 15

x *= 2;  // x = x * 2 => 30


Console.WriteLine(x); // Output: 30
