In the Program.cs file, write code to check if the value integer is less than 0 or greater than 20. Throw System.Exception if the value is outside of the range.
int value = int.Parse(Console.ReadLine());
Console.WriteLine(string.Format("You entered {0}",value));
try
{
if(value <0 || value >20)
{
throw System.Exception;
}
}
catch(Exception)
{
Console.WriteLine("value not in the permissible range");
}

{ if(value < 0 ||value > 20) { throw new System.Exception(); } } { Console.WriteLine(string.Format("You entered {0}",value)); } '''
is what finally worked for me. I got stuck on this for wayyyyy too long using try/ catch
