Answer 2

Yes, I updated my code and now it passes the unit tests. Thanks XXX MrDevEzeoke for the support. Anyway I think the scenario given in that exercise should have been little bit more clearer.

Answer 4

I also have a problem with the exercise. I added the code I wrote for the exercise but unit tests fail. I don't get how the discount works there.

Answer 5

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int discount = Convert.ToInt32(Console.ReadLine());

Dictionary<string, int> coffee = new Dictionary<string, int>();
coffee.Add("Americano", 50);
coffee.Add("Latte", 70);
coffee.Add("Flat White", 60);
coffee.Add("Espresso", 60);
coffee.Add("Cappuccino", 80);
coffee.Add("Mocha", 90);

//your code goes here

foreach (var s in coffee.Keys.ToArray())
{

coffee[s] = coffee[s] - coffee[s] * discount/100;
Console.WriteLine(s + ": "+ coffee[s]);
}

}
}
}
That´s a possible way to solve this problem using coffee.Keys.ToArray() in the foreach loop for those who asked:)

Answer 6

try this code its work

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int discount = Convert.ToInt32(Console.ReadLine());

Dictionary<string,double> coffee = new Dictionary<string, double>();
coffee.Add("Americano", 50);
coffee.Add("Latte", 70);
coffee.Add("Flat White", 60);
coffee.Add("Espresso", 60);
coffee.Add("Cappuccino", 80);
coffee.Add("Mocha", 90);

//your code goes here
foreach(KeyValuePair<string,double>entry in coffee)
{

Console.WriteLine(entry.Key+": " +(entry.Value - entry.Value * discount/100));
}

}
}
}

Answer 8

Just wondering why nobody has used the coffee.Keys.ToArray() in their solutions?

Answer 10

Tharinda Nimnajith the input represents discount percentage, not the discount itself.

Answer 11

~DevEzeoke16[BTS]~ Thanks a lot for this answer! My answer was correct in 95% of the cases, which was really bugging me ^^

Answer 12

Why do we use coffee.Keys.ToArray() instead of coffee.keys

????

Answer 13

MrDevEzeoke

Read the question again. It says that a discount value is given as input and you have to output the price of each coffee type AFTER APPLYING THE DISCOUNT.

So for example, if the input is 10, you will apply 10% discount on each coffee type. In the end the cost of
Americano = 50 - 10% of 50 = 45
and so on

foreach(var c in coffee)

Answer 15

@Richie Ro binson
Im wondering aswell.
I didn't use coffee.Keys.ToArray() either.
using System;
using System.Collections.Generic;
using System.Linq;

namespace Coffee_Time
{
class Program
{
static void Main(string[] args)
{
int discount = Convert.ToInt32(Console.ReadLine());

Dictionary<string, int> coffee = new Dictionary<string, int>();
coffee.Add("Americano", 50);
coffee.Add("Latte", 70);
coffee.Add("Flat White", 60);
coffee.Add("Espresso", 30);
coffee.Add("Cappucino", 90);
coffee.Add("Mocha", 100);

foreach (KeyValuePair<string, int>d in coffee)
{
int zahl = d.Value * discount / 100;
Console.WriteLine(quot;{d.Key}: {d.Value - zahl} ");

}

}

}
}
