Aprenda Desafio: Sobrecarga de Métodos

Neste exercício prático, você recebe uma classe ShippingCalculator com um método chamado CalculateShippingCost. O método deve ser sobrecarregado para suportar diferentes cenários de custos de envio com base no peso e no destino.

Sua tarefa é preencher corretamente os espaços em branco (___) para completar os cálculos no método CalculateShippingCost tanto para envios locais quanto internacionais.

              1234567891011121314151617181920212223242526272829303132333435363738394041424344
            
using System;

public class ShippingCalculator
{
    // Method to calculate shipping cost for local shipments
    public double CalculateShippingCost(double weight)
    {
        // Local shipments have a fixed rate of $5 per kilogram
        return weight * ___;
    }

    // Method to calculate shipping cost for international shipments
    // It has two parameters 'weight' and an additional 'destinationCountry' which is of type 'string'
    ___
    {
        // International shipments have a base rate of $10 per kilogram
        // Additional $3 per kilogram for shipments to Canada
        // Additional $5 per kilogram for shipments to other countries
        double baseRate = ___;
        double additionalRate = destinationCountry.ToLower() == "canada" ? ___ : ___;

        return weight * (baseRate + additionalRate);
    }
}

class ConsoleApp
{
    static void Main()
    {
        ShippingCalculator calculator = new ShippingCalculator();

        // Test local shipment
        double localCost = calculator.CalculateShippingCost(2);
        Console.WriteLine($"Local Shipment Cost: ${localCost}");

        // Test international shipment to Canada
        double internationalToCanadaCost = calculator.CalculateShippingCost(2, "Canada");
        Console.WriteLine($"International Shipment to Canada Cost: ${internationalToCanadaCost}");

        // Test international shipment to other countries
        double internationalToOtherCost = calculator.CalculateShippingCost(2, "Germany");
        Console.WriteLine($"International Shipment to Other Country Cost: ${internationalToOtherCost}");
    }
}

É necessário sobrecarregar o método CalculateShippingCost. Portanto, o novo método deve ter o mesmo nome, mas parâmetros diferentes. Os parâmetros necessários estão indicados nos comentários.

public class ShippingCalculator

    {
        // Local shipments have a fixed rate of $5 per kilogram
        return weight * 5;
    }

    // Method to calculate shipping cost for international shipments
    // It has two parameters 'weight' and an additional 'destinationCountry' which is of type 'string'
    public double CalculateShippingCost(double weight, string destinationCountry)
    {
        // International shipments have a base rate of $10 per kilogram
        // Additional $3 per kilogram for shipments to Canada
        // Additional $5 per kilogram for shipments to other countries
        double baseRate = 10;
        double additionalRate = destinationCountry.ToLower() == "canada" ? 3 : 5;

        return weight * (baseRate + additionalRate);
    }
}

class ConsoleApp
{
    static void Main()
    {
        ShippingCalculator calculator = new ShippingCalculator();

        // Test local shipment
        double localCost = calculator.CalculateShippingCost(2);
        Console.WriteLine($"Local Shipment Cost: ${localCost}");

        // Test international shipment to Canada
        double internationalToCanadaCost = calculator.CalculateShippingCost(2, "Canada");
        Console.WriteLine($"International Shipment to Canada Cost: ${internationalToCanadaCost}");

        // Test international shipment to other countries
        double internationalToOtherCost = calculator.CalculateShippingCost(2, "Germany");
        Console.WriteLine($"International Shipment to Other Country Cost: ${internationalToOtherCost}");
    }
}
