Question

Part (a) Write a number guessing game using System.Collections.Generic.Dictionary. Generate 10 distinct random numbers in the range of 1 to 20. Each random number is associated with a prize money (from 1 to 10000). Use a Dictionary to store the mapping between the random number and the prize money. Ask user for two distinct numbers, a and b, both from 1 to 20; if a and b are not distinct, or out of range, quit the program Lookup the prize money from both numbers and print out the sum via "You earned XXXX in total!". If the table does not contain the number, assume the prize money is 0. e.g. Suppose we generate the following random numbers and penalty money: 1 3 4 6 7 11 12 13 19 20 333 234 12 500 1569 9900 23 2 588 23 If a user guess 5 and 3, we output "You earned 234 in total!" If a user guess 1 and 13, we output "You earned 335 in total!" If a user guess 1 and 1, quit

I have done the part(a) and the code is below.

For the part(b),

If the user has earned absolutely 0 amount of prize money, tell user which number would have given them the highest prize money:

e.g. "You are unlucky! If you guessed X, you would have won the most money!"

Otherwise, if the prize money is non-zero, after telling user the prize money he/she earned, print out the list of numbers that would have caused the player to have 0 prize money.

e.g. "You are so lucky! You could have 0 money if you have guessed …."

using System;

using System.Collections.Generic;

class GuessingGame{

    public static void Main(){

        Dictionary<int, int> prizes = new Dictionary<int, int>();

        Random rndGen = new Random(0);

        int num, money;

        int i=0;

        while(i<10){

            num = rndGen.Next(1, 20);

            money = rndGen.Next(1, 10000);

            if(!prizes.ContainsKey(num)){

                prizes.Add(num, money);

                i++;

            }

        }

        Console.Write("Enter two numbers(space separated): ");

        string[] line = Console.ReadLine().Split(' ');

        int num1 = Int32.Parse(line[0]);

        int num2 = Int32.Parse(line[1]);

        if(num1==num2 || num1<1 || num1>20 || num2<0 || num2>20)

            Console.WriteLine("quit");

        else{

            int prizeMoney = 0;

            if(prizes.ContainsKey(num1))

                prizeMoney += prizes[num1];

            if(prizes.ContainsKey(num2))

                prizeMoney += prizes[num2];

            Console.WriteLine("You earned {0} in total!", prizeMoney);

        }

    }

}

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Remoting.Messaging;

class GuessingGame
{

public static void Main()
{

Dictionary<int, int> prizes = new Dictionary<int, int>();

Random rndGen = new Random(0);

int num, money;

int i = 0;

while (i < 10)
{

num = rndGen.Next(1, 20);

money = rndGen.Next(1, 10000);

if (!prizes.ContainsKey(num))
{

prizes.Add(num, money);

i++;

}

}

Console.Write("Enter two numbers(space separated): ");

string[] line = Console.ReadLine().Split(' ');

int num1 = Int32.Parse(line[0]);

int num2 = Int32.Parse(line[1]);

if (num1 == num2 || num1 < 1 || num1 > 20 || num2 < 0 || num2 > 20)

Console.WriteLine("quit");

else
{

int prizeMoney = 0;

if (prizes.ContainsKey(num1))

prizeMoney += prizes[num1];

if (prizes.ContainsKey(num2))

prizeMoney += prizes[num2];

Console.WriteLine("You earned {0} in total!", prizeMoney);

if (prizeMoney == 0)
{
int maxValue = prizes.Max(aPair => aPair.Value);
KeyValuePair<int,int> maxPair = prizes.First(aPair=> (aPair.Value == maxValue));
Console.WriteLine($"You are unlucky!If you guessed {maxPair.Key},You would have won the most money!");
}
else
{
var list = new List<int>();
for (int k = 1;k <= 20;k++)
{
if (!prizes.ContainsKey(k))
{
list.Add(k);
}
}
Console.WriteLine("You are so lucky! You could have 0 money if you have guessed");

foreach (var item in list)
{
Console.WriteLine(item);
}
}
}

  

}

}
