passing parameters with ref

Lovemore Kutseya

write the method called currentLargestSum which takes an array of integers and another integer result, passed using the ref keyword.

If the sum of the numbers in the array is larger than the current result then assign the sum to the result. Otherwise leave result unchanged

using System;

namespace HelloWorld
{
class Program
{
static void Main(string[] args)
{
int largestSum = 0;
int[] numbers1 = { 10, 12, 3, 2, 45, 6 };
currentLargestSum(numbers1, ref largestSum);
string result = largestSum + ", ";
int[] numbers2 = { 10, 1, 3, 2, 45, 6 };
currentLargestSum(numbers2, ref largestSum);
result += largestSum + ", ";
int[] numbers3 = { 104, 132, 13, 2, 45, 6 };
currentLargestSum(numbers3, ref largestSum);
result += largestSum;
Console.WriteLine(result);
}
}
}

HI Lovemore,
You dont want to go for another variable too, Becaus directly we can pass the "largestsum" variable itself as ref parameter.

class Program
{
   public static void currentLargestSum(int[] arr, ref int x)
   {
      if(x < arr.Sum())
      {
         x = arr.Sum();
      }
   }
   static void Main(string[] args)
   {
      int largestSum = 0;
      int[] numbers1 = { 10, 12, 3, 2, 45, 6 };
      currentLargestSum(numbers1, ref largestSum);
      //string result = largestSum + ", ";
      int[] numbers2 = { 10, 1, 3, 2, 45, 6 };
      currentLargestSum(numbers2, ref largestSum);
      //result += largestSum + ", ";
      int[] numbers3 = { 104, 132, 13, 2, 45, 6 };
      currentLargestSum(numbers3, ref largestSum);
      //result += largestSum;
      Console.WriteLine(largestSum);
      Console.ReadLine();
   }
}
