Question

Fix program errors and improve code

Visual Studio C# Console App (.NET Framework)

Task

The program must allow for the teacher to either enter a predetermined number of scores
(e.g. 10 exam scores), to keep allowing them to enter in scores until they are
finished. You will need to convert these scores to a percentage then store these in a list.

You will perform some calculations on these results and also display the contents of
the list (percentage values) back to the user. You will need to provide evidence showing that
you have tested your across a range of inputs and the matching end results. This could be in
the form of multiple screen shots and/or a table showing all your tested inputs and the
corresponding results etc.

[If the user enters the raw scores: 15, 50, 70, 25 the program will convert and store
these as percentages as 20%, 68%, 95% and 34% respectively (test is out of 50). The
program will then return the average of 54%, maximum 95%, minimum 20%, number of
entries 4 and the sum of 216%. The sorted list is also displayed, e.g. 20%, 34%, 68%, 95%.
Your program should also provide descriptions of what your code aims to achieve through
good commenting (notes). Add any other useful enhancements that you wish to use to help
showcase your skills from within this topic.]

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new Console Application in C# is created using Visual Studio 2017 with name "Assessment".This application contains a program with name "Program.cs".Below are 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 Assessment
{
class Program //Class
{
static void Main(string[] args)//Main method
{
List<double> testResults = new List<double>();
const int MIN = 0; //Determine the Maximum and Minimum value range of the test
const int MAX = 74;//max
int userInput; //Determines the variables
int userInput2;
bool numOfEntries;
bool numOfResults;
//asking to enter number of score
Console.WriteLine("How many Science Test Scores do you want to enter?");
numOfEntries = int.TryParse(Console.ReadLine(), out userInput);//reading and parsing input
while (numOfEntries == false || userInput < MIN)
if (numOfEntries == false) //for invalid input
{
Console.WriteLine("Please enter a valid number!");
numOfEntries = int.TryParse(Console.ReadLine(), out userInput);

}
else if (userInput < MIN)
{
Console.WriteLine("Please enter a valid number above 0!");
numOfEntries = int.TryParse(Console.ReadLine(), out userInput);
}

for (int i = 0; i < userInput; i++) //Repeat as much times as the user inputs
{
Console.WriteLine("Please enter your test result!");
numOfResults = int.TryParse(Console.ReadLine(), out userInput2);
while (numOfResults == false || userInput2 >= MAX || userInput2 < MIN)
  
if (numOfResults == false)//for invalid input
{
Console.WriteLine("Please enter a valid number!");
numOfResults = int.TryParse(Console.ReadLine(), out userInput2);
}
else if (userInput2 >= MAX)
{
Console.WriteLine("Please enter a valid number below 74!");
numOfResults = int.TryParse(Console.ReadLine(), out userInput2);
}
else if (userInput2 < MIN)
{
Console.WriteLine("Please enter a valid number above 0!");
numOfResults = int.TryParse(Console.ReadLine(), out userInput2);
}
//add score in the list
testResults.Add(Math.Round(userInput2 / (double)MAX * 100));
  
}
//sort the list
testResults.Sort();
Results(testResults);//call method
Console.WriteLine("Your list of numbers are as follows: ");
//display numbers
foreach (var num in testResults)
{
Console.WriteLine(num);//display test scores
}
Console.ReadKey();
}
//Method defination
static void Results(List<double> resultsInAMMSC) //AMMSN is Average, Maximum, Minimum, Sum and Count
{
Console.WriteLine("Average :" + resultsInAMMSC.Average() + "%"); //Shows the user what their inputs are in AMMSN
Console.WriteLine("Maximum :" + resultsInAMMSC.Max() + "%");//display Max
Console.WriteLine("Minimum :" + resultsInAMMSC.Min() + "%");//display min
Console.WriteLine("Sum :" + resultsInAMMSC.Sum());//display sum
Console.WriteLine("results :" + resultsInAMMSC.Count());//display count
}
}
}
