Problem with a Vehicle Catalogue

I am trying to solve a problem where i need to create something like a vehicle catalogue it works for the most part but im still not getting the right answers on some inputs this is my code: https://pastebin.com/n82eac2U

Does it work for the example input?

StaskOP•11mo ago

yes

One of the requirements is to print $"{typeOfVehicle} have average horsepower of: {horsePower}." You have hardcoded Trucks and Cars What if the user creates a new vehicle of type Scooter?

StaskOP•11mo ago

its said in the constraints that it will either be a car or a truck

I wonder if it maybe expects you to print the average HP even if there are no vehicles of that type The exercise says print one and the other So it might just expect the evrage of trucks to be 0.00 when there are no trucks It's mostly just guesswork, though, without knowing what the tests are ¯\_(ツ)_/¯

i will try without them yeah pretty annoying i thought someone could maybe spot a rookie mistake here nope still not working

You can try it with this code

c#
class Program
{
    private const string END_OF_PARSE = "End";
    private const string END_OF_QUERY = "Close the Catalogue";

    public static void Main( string[] args )
    {
        var vehicles = ParseVehicles().ToList();
        QueryVehicles( vehicles );
        PrintStatistics( vehicles );
    }

    private static IEnumerable<Vehicle> ParseVehicles()
    {
        while ( true )
        {
            var input = Console.ReadLine();
            if ( input == END_OF_PARSE ) yield break;
            if ( input is null ) continue;

            var parts = input.Split( " " );
            yield return new Vehicle
            {
                Type = Enum.Parse<VehicleType>( parts[0], true ),
                Model = parts[1],
                Color = parts[2],
                Horsepower = int.Parse( parts[3] ),
            };
        }
    }

    private static void QueryVehicles( ICollection<Vehicle> vehicles )
    {
        while ( true )
        {
            var input = Console.ReadLine();
            if ( input == END_OF_QUERY ) return;

            var v = vehicles.FirstOrDefault( e => e.Model.Equals( input ) );
            if ( v is null )
                continue;

            foreach ( var prop in typeof( Vehicle ).GetProperties() )
            {
                Console.WriteLine( "{0}: {1}", prop.Name, prop.GetValue( v ) );
            }
        }
    }

    private static void PrintStatistics( ICollection<Vehicle> vehicles )
    {
        foreach ( var group in vehicles.GroupBy( e => e.Type ).OrderBy( g => g.Key ) )
