5.39 - Function GetMinMax

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.


Resolution
using System;
class Program
{
    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);
    }
}
