Problem description

Your task is to create a repository, which stores items by creating the classes described below.

First, write a C# class Car with the following properties:

Manufacturer: string
Model: string
Year: int

The class constructor should receive manufacturer, model and year and override the ToString() method in the following format:

"{manufacturer} {model} ({year})"

Next, write a C# class Parking that has data (a collection, which stores the entity Car). All entities inside the repository have the same properties. Also, the Parking class should have those properties:

Type: string
Capacity: int

The class constructor should receive type and capacity, also it should initialize the data with a new instance of the collection. Implement the following features:

Field data – collection that holds added cars
Method Add(Car car) – adds an entity to the data if there is an empty cell for the car.
Method Remove(string manufacturer, string model) – removes the car by given manufacturer and model, if such exists, and returns bool.
Method GetLatestCar() – returns the latest car (by year) or null if have no cars.
Method GetCar(string manufacturer, string model) – returns the car with the given manufacturer and model or null if there is no such car.
Getter Count – returns the number of cars.
– returns a string in the following format:
- "The cars are parked in {parking type}:
  {Car1}
  {Car2}
  (…)"

Constraints

The combinations of manufacturers and models will be always unique.
The year of the cars will always be positive.
There won't be cars with the same years.

Examples

This is an example how the Parking class is intended to be used.

Sample code usage

// Initialize the repository

Parking parking = new Parking("Underground parking garage", 5);

// Initialize entity

Car volvo = new Car("Volvo", "XC70", 2010);

// Print Car

Console.WriteLine(volvo); // Volvo XC70 (2010)

// Add Car

parking.Add(volvo);

// Remove Car

Console.WriteLine(parking.Remove("Volvo", "XC90")); // False

Console.WriteLine(parking.Remove("Volvo", "XC70")); // True

Car peugeot = new Car("Peugeot", "307", 2011);

Car audi = new Car("Audi", "S4", 2005);

parking.Add(peugeot);

parking.Add(audi);

// Get Latest Car

Car latestCar = parking.GetLatestCar();

Console.WriteLine(latestCar); // Peugeot 307 (2011)

// Get Car

Car audiS4 = parking.GetCar("Audi", "S4");

Console.WriteLine(audiS4); // Audi S4 (2005)

// Count

Console.WriteLine(parking.Count); // 2

// Get Statistics

Console.WriteLine(parking.GetStatistics());

// The cars are parked in Underground parking garage:

// Peugeot 307(2011)

// Audi S4(2005)

Submission

Zip all the files in the project folder except bin and obj folders.

public string GetStatistics() { var sb = new StringBuilder(); string information = $"The cars are parked in {this.Type} parking garage."; sb.AppendLine(information); foreach (var car in this.data) { sb.AppendLine(car.ToString()); } return sb.ToString().TrimEnd(); }

public string GetStatistics() { StringBuilder sb = new StringBuilder(); sb.AppendLine($"The cars are parked in {this.Type}:"); foreach (var car in this.data) { sb.AppendLine(car.ToString()); } return sb.ToString().TrimEnd(); }

Thanks a lot and to @MartinBG , who helped me in the basic module, show me how to work with multidimensional arrays and streams.

Thanks and to @ nickwork , who helped me a lot in basic and fundamental.
