Experts,

Details
I am trying to create a scoring system where the user will input names and scores of all players. The program will calculate the average score and display all the players who scored below average.  

Sample Output
Enter Player Name (Q to quit): Bob

Enter score for Bob: 3245

Enter Player Name (Q to quit): Sue

Enter score for Sue: 1098
Enter Player Name (Q to quit): Q

Name     Score

Bob        3245

Sue        1098
Average Score: 3944.75

Players who scored below average

Name     Score

Bob        3245
Sue        1098

Variables
My variables are:
 InputData( ): Requests the user to input the player names and scores from the user and stores them into the two arrays for an unknown number of players <= 100.  
DisplayPlayerData(): Displays each player's name and score.
CalculateAverageScore( ): Calculates the average score and returns it by value.  
DisplayBelowAverage( ): Displays the names and scores of players who scored below average.

Comments
Any ideas how to tackle this? New to C#, trying to figure out the code

Thank you very much in advance!

Yes, that obvious, huh. I have identified the methods. How can I get the names and scores from the user and place them into an array?
using System;

namespace Wk5_LabA
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] playerNameAr = new string[100];
            double[] scoreAr = new double[100];
            int numPlayers = 0;
            double averageScore;


            static void InputData(playerNameAr, scoreAr, ref numPlayers);
            Console.WriteLine("Please enter");
            
            foreach  string(string playerNameAr in playerName)
            {
                Console.WriteLine(playerNameAr)
            };
            Console.ReadLine();


            static void DisplayPlayerData(playerNameAr, scoreAr, numPlayers);

            static void averageScore = CalculateAverageScore(scoreAr, numPlayers);
            Console.WriteLine("\nAverage Score: {0:F}", averageScore);

            static void DisplayBelowAverage(playerNameAr, scoreAr,numPlayers, averageScore);
            Console.Read();

        }
    }
}

The description doesn't specify if the arrays must be passed into the methods.  Do you know if you're allowed to use static arrays and variables?

Here's a possible setup:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {

        static string[] playerNameAr = new string[100];
        static double[] scoreAr = new double[100];

        public static void Main(string[] args)
        {
            int numPlayers = InputData();
            DisplayPlayerData(numPlayers);
            double averageScore = CalculateAverageScore(numPlayers);
            Console.WriteLine("\nAverage Score: {0:F}", averageScore);
            DisplayBelowAverage(numPlayers, averageScore);

            Console.Write("Press Enter to Quit");
            Console.ReadLine();
        }

        public static int InputData()
        {
            // do while name isn't "Q", store name/score and increment counter
            // return the counter value
        }

        public static void DisplayPlayerData(int numPlayers)
        {
            // iterate over arrays up to "numPlayers" and output
        }

        public static double CalculateAverageScore(int numPlayers)
        {
            // iterate over array up to "numPlayers" and keep running total, return average
        }

        public static void DisplayBelowAverage(int numPlayers, double avg)
        {
            //iterate over array up to "numPlayers" and output those less than the average
        }

    }
}

Yes, static arrays and variables are allowed. It is a basic example of the use of arrays, not sure why I am struggling with this basic concept.

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!
