C# Increment
What is the use of Increment and Decrement operator in C# ?
- In C#- Programming Increment operators (++) is used to increase the value of the variable by one.
- In C#- Programming decrement operators (--) is used to decrease the value of the variable by one.
Increment and Decrement Operator
Syntax:
Increment operator: ++var_name; (or) var_name++;
Decrement operator: - -var_name; (or) var_name - -;
C# Sample Code - C# Examples:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace wikitechy_inc_dec_operators
{
class Program
{
static void Main(string[] args)
{
int a = 1;
Console.WriteLine(" post increment value is : {0}", a++);
Console.WriteLine(" pre increment value is : {0}", ++a);
Console.WriteLine(" post decrement value is : {0} ", a--);
Console.WriteLine(" pre decrement value is : {0} ", --a);
Console.ReadLine();
}
}
}
Code Explanation:
- In this statement we declared and assigned the value "5" for the variable "a".
- In this statement, the post increment operation will be performed where the "a" value is incremented and stored in the variable(a=5), since it is post increment so the value will be printed only for the current value of "a" (a=5).
- In this statement, the pre increment operation will be performed where the value of "a=5" because previously the value will be increment which will be stored in the variable "a", so now the value printed in the console display window will be "7" (a=7becasuse of these pre increment).
- In this statement, the pre decrement operation will be performed where the value of "a" is 7 (a=2 it has been pre decremented), so the value printed in the console display window for "a" will be "7".
- In this, the printf statement post decrement operation will be performed where the value of "a" is 7, since it is the post decrement operation the value of a=2 is decremented and stored in the variable. In the output the current value of "a=5" will be printed.
Sample C# examples - Output :
- Here in this output the post increment operation will be performed so the variable "a" value (5) will be displayed.
- Here in this output the pre increment operation will be performed so the variable "a" value (7) will be displayed.
- Here in this output the pre decrement operation will be performed so the variable "a" value (7) will be displayed.
- Here in this output the post decrement operation will be performed so the variable "a" value (5) will be displayed.
