Question

C# programming

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

* Please use seeded random generation to help you debug your code, i.e. "Random rand = new Random(0);"

**You may have the following properties/methods useful: Count, ContainsKey, Add

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);

        }

    }
