Question

Create a C# program that will first prompt the instructors to enter the number of students they currently have in their classes. Use this value for the size of the row dimension of your multidimensional array.

Next, prompt the instructors to type in the number of scores they would like to enter. This variable will be used to designate the column size dimension of your multidimensional array.

Then, use a loop to prompt the user to enter the number of scores they specified for each student listed in the first prompt. This means if the user entered 2 for the first prompt and 10 for the second prompt, you would prompt the instructor a total of 20 times. Make sure you label the student number in your prompt, similar to the example below.

You could say "Enter Student 1 Score" and the second prompt would be

"Enter Student 1 Score," and so on.

C# Program:

using System.IO;
using System;

class Program
{
    static void Main()
    {
        int students, scores;
      
        //Reading number of students - row
        Console.Write("\n Input number of students: ");
        students = Convert.ToInt32(Console.ReadLine());
      
        //Reading number of scores - column
        Console.Write("\n Input number of scores: ");
        scores = Convert.ToInt32(Console.ReadLine());
      
        //Array to hold studentScores
        int[,] studentScores = new int[students,scores];
      
        Console.WriteLine();
      
        //Reading scores from user
        for(int i=0; i<students; i++)
        {
            for(int j=0; j<scores; j++)
            {
                //Prompting user for score
                Console.Write(" Enter Student " + (i+1) + " Score " + (j+1) + ": ");
              
                //Reading and storing in array
                studentScores[i,j] = Convert.ToInt32(Console.ReadLine());
            }
          
            Console.WriteLine();
        }
      
          
        Console.WriteLine("\n\n Student Scores are: \n");
        Console.WriteLine("\n Student \t\t Scores \n");
      
        //Iterating over students
        for(int i=0; i<students; i++)
        {
            //Prompting user for score
                Console.Write("\n   " + (i+1) + " \t\t ");
              
            //Itreating over scores
            for(int j=0; j<scores; j++)
            {
                //Prompting user for score
                Console.Write(" " + studentScores[i,j]);
            }
        }
      
        Console.WriteLine();
    }
}
