//Problem 1.    Exchange If Greater
//Write an if-statement that takes two integer variables a and b and exchanges their values if the first one is greater than the second one. As a result print the values a and b, separated by a space. Examples:

using System;

class ExchangeIfGreater
{
    static void Main()
    {
        Console.Write("Please, enter a:");
        double a = double.Parse(Console.ReadLine());
        Console.Write("Please, enter b:");
        double b = double.Parse(Console.ReadLine());
        if (a > b)
        {
            Console.WriteLine("Exchange needed:{0} <===> {1}",a,b);
            double greaterNumber = a;
            a=b;
            b=greaterNumber;
            Console.WriteLine(a + " " + b);
        }
        else
        {
            Console.WriteLine("No Exchange needed:{0} <===> {1}",a,b);
            Console.WriteLine(a + " " + b);
        }
    }
