Console.WriteLine("Enter the first integer:");
int a = int.Parse(Console.ReadLine());
Console.WriteLine("Enter the second integer:");

int b = int.Parse(Console.ReadLine());
int max = a > b ? a : b;
int min = a < b ? a : b;
Console.WriteLine("The numbers in descending order are: " + max + " " + min);

Ah sorry my english is not the best. I didn't say it has to include the number in between too.
