Ask the user how many high scores they want.
// Then read in their input.
// Support error checking (input validation).
// The user should only be able to input a positive
// integer value.
// You may use Utility. ReadIng() and Utility. IsRael Good()
// to help you with error checking.

Explanation:

As per requirement submitted above kindly find below solution.

Here new console application in C# is created using visual studio 2019 with name "HighScoreApp". This application contains a class with name "Program.cs".Below is the details of this class.

Program.cs :

//namespace

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

//application namespace

namespace HighScoreApp

{

class Program //C# class

{

//entry point of the program , Main() method

static void Main(string[] args)

{

//declaring variable to store number of score

int numberOfScores = 0;

//using while loop

while(numberOfScores<=0)

{

//asking user number of high scores

Console.WriteLine("Enter number of high scores : ");

//reading input

numberOfScores = int.Parse(Console.ReadLine());

}

//declaring array with number of scores

int[] scores = new int[numberOfScores];

//asking user high scores using for loop

for (int i = 0; i < scores.Length; i++)

{

//asking high scores

Console.WriteLine("Enter score "+(i+1)+" : ");

//reading score

scores[i] = int.Parse(Console.ReadLine());

}

Console.WriteLine();//used for new line

Console.WriteLine("High Scores -Unsorted");

//call function to print each element

PrintArray(scores);

//call method to sort the array elements

scores = SortArrayHighToLow(scores);

Console.WriteLine();//used to print new line

Console.WriteLine("High Scores-Sorted");

PrintArray(scores);//call method to print array elements

Console.SetCursorPosition(0, Console.WindowHeight - 1);

Console.WriteLine("Press ENTER to continue....");

Console.ReadLine();

}

//method to print the array

public static void PrintArray(int [] scoresArray)

{

//using for loop , print each score

for (int i = 0; i < scoresArray.Length; i++)

{

Console.WriteLine(scoresArray[i]);//print each high score

}

}

//method to sort the array

public static int [] SortArrayHighToLow(int[] scoresArray)

{

Array.Sort(scoresArray);

return scoresArray;

}

}

}
