What are increment (++) and decrement (--) operators in C#?

Increment Operators

To increment a value in C#, you can use the increment operators i.e. Pre-Increment and Post-Increment Operators.

The following is an example −

Example

using System; class Demo {    static void Main() {       int a = 250;       Console.WriteLine(a);       a++;       Console.WriteLine(a);       ++a;       Console.WriteLine(a);       int b = 0;       b = a++;       Console.WriteLine(b);       Console.WriteLine(a);       b = ++a;       Console.WriteLine(b);       Console.WriteLine(a);    } }

Decrement Operators

To decrement a value in C#, you can use the decrement operators i.e. Pre-Decrement and Post-Decrement Operators.

The following is an example −

Example

using System; class Demo {    static void Main() {       int a = 250;       Console.WriteLine(a);       a--;       Console.WriteLine(a);       --a;       Console.WriteLine(a);       int b = 0;       b = a--;       Console.WriteLine(b);       Console.WriteLine(a);       b = --a;       Console.WriteLine(b);       Console.WriteLine(a);    } }
