Function GetMinMax 78


Objetive:

Create a function named "GetMinMax", which will ask the user for a minimum value (a number) and a maximum value (another number). It should be called in a similar way to

GetMinMax( n1, n2);

which would behave like this:
Enter the minimum value: 5
Enter the maximum value: 3.5
Incorrect. Should be 5 or more.
Enter the maximum value: 7

That is: it should ask for the minimum value and then for the maximum. If the maximum is less than the minimum, it must be reentered. It must return both values.


Code:

using System;
public class exercise132
{
    public static void GetMinMax(ref float number1, ref float number2)
    {
        Console.Write("Enter the minimum value: ");
        number1 = Convert.ToSingle(Console.ReadLine());

        Console.Write("Enter the maximum value: ");
        number2 = Convert.ToSingle(Console.ReadLine());

        while (number2 < number1)
        {
            Console.WriteLine("Incorrect. Should be {0} or more.", number1);
            Console.Write("Enter the maximum value: ");
            number2 = Convert.ToSingle(Console.ReadLine());
        }
    }
    static void Main(string[] args)
    {
        float number1 = 000000000.00f, number2 = 000000000.00f;
        GetMinMax(ref number1, ref number2);
    }
}
