Console.Write("Enter size of the two-dimensional array: ");
int size = int.Parse(Console.ReadLine());
int[,] squareArray = new int[size, size];
for (int i = 0; i < size; i++)
{
for (int j = 0; j < size; j++)
{
Console.Write("Enter element[{0}][{1}]: ", i, j);
squareArray[i, j] = int.Parse(Console.ReadLine());
}
}
int product = 1;
for (int i = 0; i < size; i++)
{
for (int j = 0; j < size; j++)
{
if (squareArray[i, j] < 0) {
product *= squareArray[i, j];
}
}
}
Console.WriteLine("The product of the negative elements : {0}", product);
Console.ReadLine();
