sum input values

Let see other C# code examples of using loops--for loop, while loop, and do while loops to enable a user to input a number of data points and then calculate the total of the data values. We provide three separate C# code examples to solve the same problem. One C# code example is using for loop and the two others are using while loop , and do while loop.

Example 1: C# code using for loop 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)
{

  sumValues();
  Console.ReadLine();


}

static void sumValues()
{


  int sum = 0,val,n, i;
  Console.Write("Enter number of data points:");
  n = int.Parse(Console.ReadLine());
  for (i = 0; i < n; i++)
 
{
   Console.Write("Values " + i+":");
   val = int.Parse(Console.ReadLine());
   sum += val;
}

 Console.WriteLine("Total:" + sum);

}

Example 2: C# code using while loop 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)
 
{
     sumValues();
     Console.ReadLine();

}

  static void sumValues()
 
{
    int sum = 0, val,n, i=0;
    Console.Write("Enter number of data points:");
    n = int.Parse(Console.ReadLine());
    while (i<n)
  
{
     Console.Write("Values " + i+":");
     val = int.Parse(Console.ReadLine());
     sum += val;
     i += 1;
   
}

   Console.WriteLine("Total:" + sum);

}

Example 3: C# code using do while loop 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)
 
{
    sumValues();
    Console.ReadLine();

}

  static void sumValues()
 
{
   int sum = 0, val,n, i=0;
   Console.Write("Enter number of data points:");
   n = int.Parse(Console.ReadLine());
  do
 
{
    Console.Write("Values " + i + ":");
    val = int.Parse(Console.ReadLine());
    sum += val;
    i += 1;
  }while (i < n);

 Console.WriteLine("Total:" + sum);

}
