Proposed exercise
Write a C# program to ask the user for marks for 20 pupils (2 groups of 10, using a two-dimensional array), and display the average for each group.
Output
Solution
using System; public class TwoDimensional { public static void Main() { float[ , ] puntuations = new float[10,10]; for (int i = 0; i < 2; i++) { for (int j = 0; j < 10; j++) { Console.WriteLine("Enter the puntuation {0} group {1}: ", j+1,i+1); puntuations[i,j] = Convert.ToSingle( Console.ReadLine() ); } } } }
