C# tutorial- Arrays: sum all elements of an integer array


sum all elements of an integer array

In this page, we provide one more C# code example that sums all elements of an integer array.
To sum all elements of an array you need to use a loop to traverse through the array(using every index). Each element of the array will be cumulated in to a variable. For the C# code example below, we allow a user to input a number of his/her data points then the program will display the total of the data set.

Example: C# code to sum all elements of an integer array

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace ConsoleApplication1
{
class Program
{

static void Main(string[] args)
{


  sumArray();
  Console.ReadLine();


}

static void sumArray()
{

  int sum=0,n,i=0;
  Console.Write ("Enter number of data points:");
  n=int.Parse(Console.ReadLine()) ;
  int[] arr=new int[n];
  do{
     Console.Write ("Values[{0}",i+"]:");
     arr[i]=int.Parse (Console.ReadLine() ) ;
     sum+=arr[i];
     i+=1;
    } while(i<n);
  Console.WriteLine ("Total:{0}",sum);
   }


  }
}
