Question

Using visual studio C#

Create a method for generating 3 random scores.
You decide to go for array/list/dictionary. Set the return type and other stuff consistently.
Use a loops inside the method to generate random scores and assign scores to the data structure.
Return the structure as a whole.
Clarification: One run of the method is to generate data for one student. You need to run the method 4 times, one for each student.

Keep other things the same. That is:

2-dimension structure

Calculate average score

Display all scores and average score

Call students as Jim, Corey, Rick, and Bryan

Hi,

Program:

// C# program to demonstrate the
// boolean data type
using System;
using System.Collections;
using System.Collections.Generic;

namespace ValueTypeTest {
  
   class GeeksforGeeks {
      
   // Main function
   static void Main()
   {
      
       Console.WriteLine("----------------");

       Console.WriteLine("Jim marks:");
      
       int sum =0;
       ArrayList jim = genscores();
       foreach(int i in jim)
{
Console.WriteLine(i);
sum +=i;
}
       Console.WriteLine("Average:" + sum/3);
      
       Console.WriteLine("----------------");

       Console.WriteLine("Corey marks:");
      
       sum =0;
       ArrayList c = genscores();
       foreach(int i in c)
{
Console.WriteLine(i);
sum +=i;
}
       Console.WriteLine("Average:" + sum/3);
      
       Console.WriteLine("----------------");
       Console.WriteLine("Rick marks:");
      
       sum =0;
       ArrayList r = genscores();
       foreach(int i in r)
{
Console.WriteLine(i);
sum +=i;
}
       Console.WriteLine("Average:" + sum/3);
      
       Console.WriteLine("----------------");

       Console.WriteLine("Bryan marks:");
      
       sum =0;
       ArrayList b = genscores();
       foreach(int i in b)
{
Console.WriteLine(i);
sum +=i;
}
       Console.WriteLine("Average:" + sum/3);
  
   }
  
   static ArrayList genscores(){
  
   Random rand = new Random();

ArrayList myList = new ArrayList(10);
  
for(int i=0;i<3;i++){
int index = rand.Next(40, 100);
myList.Add(index);
}
return myList;
}
}
}

output:

----------------
Jim marks:
93
41
40
Average:58
----------------
Corey marks:
98
52
88
Average:79
----------------
Rick marks:
98
52
88
Average:79
----------------
Bryan marks:
98
52
88
Average:79

Screenshot:

Jim marks: 75 88 Average: 71 Corey marks: Average: 71 Rick marks: 75 Average: 71 Bryan marks: 75 Average: 71
