Proposed exercise
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.
Output
Solution
using System;
class GMinMax
{
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);
}
}
