Average for group 2 is 4,7

public class TwoDimensionalArray

public static void Main(string[] args)
{
int totalByGroup = 5;
float[,] puntuations = new float[totalByGroup, totalByGroup];
float totalGroup1 = 0.0f, totalGroup2 = 0.0f;
// Get puntuations
for (int i = 0; i < 2; i++)
{
for (int j = 0; j < totalByGroup; j++)
{
puntuations[i, j] = Convert.ToSingle(Console.ReadLine());
}
}
// Calculate average group 1
for (int i = 0; i < totalByGroup; i++)
{
totalGroup1 += puntuations[0, i];
}
Console.WriteLine("Average for group 1 is {0}", totalGroup1 / totalByGroup);
// Calculate average group 2
for (int i = 0; i < totalByGroup; i++)
{
totalGroup2 += puntuations[1, i];
}
Console.WriteLine("Average for group 2 is {0}", totalGroup2 / totalByGroup);
