Answer to Question #320399 in C# for kun

Question

Write a program that does the following for 15

students:

 Reads in 3 marks for each student (you

need to ensure that only valid marks

between 0 and 100 are processed) – your

prompt message to the user should

indicate which number is being requested

(see example image of output)

 Calculates and displays the highest mark

for each student.

Finds and displays the highest mark in the class.

(Note: The example output only shows data for 5

students, but your program must work for 15

students).

Answer 1

using System;

namespace students
{
    class Program
    {
        public static void Main(string[] args)
        {
            int n = 2;
            int max_mark;
            int[,] marks = new int[n,3];
            for (int i = 0; i<n; i++)
                for (int j=0; j<3; j++)
                {
                    Console.Write("Enter sudetnt {0}, mark {1}: ", i+1, j+1);
                    marks[i,j]=Convert.ToInt32(Console.ReadLine());
                    while ((marks[i,j]<0) || (marks[i,j]>100))
                    {
                        Console.WriteLine();
                        Console.Write("Mark is invalid.\nPlease re-input mark: ");
                        marks[i,j]=Convert.ToInt32(Console.ReadLine());
                    }
                }
                
            Console.WriteLine();
            for (int i = 0; i<n; i++)
            {
                max_mark = marks[i,0];
                for (int j = 0; j<3; j++)
                {
                    if (max_mark < marks[i,j])
                    {
                        max_mark = marks[i,j];                        
                    }
                }
                Console.WriteLine("Student {0} highest mark: {1}", i+1, max_mark);
            }

            Console.Write("Press any key to continue . . . ");
            Console.ReadKey(true);
        }
    }
}
