Question

(C#, Visual Studio)

I need help modifying my program code to accommodate repeated numbers. For example, if a user inputs a repeated number the program should regenerate or ask to enter again.

If needed, here is the program requirements:

Create a lottery game application. Generate four random numbers, each between 1 and 10. Allow the user to guess four numbers. Compare each of the user’s guesses to the four random numbers and display a message that includes the user’s guess, the randomly determined four numbers, and amount of money the user has won as follows:
Any One matching: $10
Two matching: $30
Three matching: $100
Four matching, not in order: $1000
Four matching, in exact order: $10000
No matches: $0

Make certain that your program accommodates repeating number. Save the file as Lottery.cs.

Hint:
Random RanNumber= new Random(); Int ran1; ran1= RanNumber.Next(min,max);

My program code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Lottery

{

    class Lottery

    {

        static void Main(string[] args)

        {

            // This will generate the 4 random numbers input by the user

            Random RanNumber = new Random();

            int ran1 = RanNumber.Next(1, 10);

            int ran2 = RanNumber.Next(1, 10);

            int ran3 = RanNumber.Next(1, 10);

            int ran4 = RanNumber.Next(1, 10);

            int temporary1 = ran1, temporary2 = ran2, temporary3 = ran3, temporary4 = ran4;

            // This will prompt the user to input the 4 numbers and read the users input

            Console.WriteLine("\nGuess four numbers between 1 and 10:");

            int userGuess1, userGuess2, userGuess3, userGuess4;

            // This will convert the string reperesentation of a number to a 32-bit signed integer

            userGuess1 = Int32.Parse(Console.ReadLine());

            userGuess2 = Int32.Parse(Console.ReadLine());

            userGuess3 = Int32.Parse(Console.ReadLine());

            userGuess4 = Int32.Parse(Console.ReadLine());

            int temporaryGuess1 = userGuess1, temporaryGuess2 = userGuess2, temporaryGuess3 = userGuess3, temporaryGuess4 = userGuess4;

            // This if statement will help with handling duplicate numbers that are entered and compared

            if (ran1 == ran2)

                ran1 = 0;

            if (ran1 == ran3)

                ran1 = 0;

            if (ran1 == ran4)

            if (userGuess1 == ran1 || userGuess1 == ran2 || userGuess1 == ran3 || userGuess1 == ran4)

                numbersMatched++;

Answer 1

Dear student,

I have added the code where it asks the user to re-enter the values if they are same or repeated

also i have added similar code to random generated numbers where if any random number is repeated it will regenerate a new random number

by doing the above i thought of removing your code where duplicate values are made 0 because it will never be used as the numbers are unique and distinct.

please find the below code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace Lottery
{

class Lottery
{

static void Main(string[] args)
{

// This will generate the 4 random numbers input by the user

Random RanNumber = new Random();

int ran1 = RanNumber.Next(1, 10);

int ran2 = RanNumber.Next(1, 10);
while (ran1 == ran2)
{
ran2 = RanNumber.Next(1, 10);
}
int ran3 = RanNumber.Next(1, 10);
while (ran1 == ran3 || ran2 == ran3)
{
ran3 = RanNumber.Next(1, 10);
}
int ran4 = RanNumber.Next(1, 10);
while (ran1 == ran4 || ran2 == ran4 || ran3 == ran4)
{
ran4 = RanNumber.Next(1, 10);
}
int temporary1 = ran1, temporary2 = ran2, temporary3 = ran3, temporary4 = ran4;

// This will prompt the user to input the 4 numbers and read the users input

Console.WriteLine("\nGuess four numbers between 1 and 10:");

int userGuess1, userGuess2, userGuess3, userGuess4;

// This will convert the string reperesentation of a number to a 32-bit signed integer

userGuess1 = Int32.Parse(Console.ReadLine());

userGuess2 = Int32.Parse(Console.ReadLine());
while (userGuess1 == userGuess2)
{
Console.WriteLine("\nPlease re-enter 2nd guess");
userGuess2 = Int32.Parse(Console.ReadLine());
}
userGuess3 = Int32.Parse(Console.ReadLine());
while (userGuess1 == userGuess3 || userGuess2==userGuess3)
{
Console.WriteLine("\nPlease re-enter 3nd guess");
userGuess3 = Int32.Parse(Console.ReadLine());
}
userGuess4 = Int32.Parse(Console.ReadLine());
while (userGuess1 == userGuess4 || userGuess2==userGuess4|| userGuess3==userGuess4)
{
Console.WriteLine("\nPlease re-enter 4nd guess");
userGuess4 = Int32.Parse(Console.ReadLine());
}
int temporaryGuess1 = userGuess1, temporaryGuess2 = userGuess2, temporaryGuess3 = userGuess3, temporaryGuess4 = userGuess4;

  

int numbersMatched = 0;

bool inOrder = false;

// This will check for matches once the user inputs their guess and the numbers that are randomly selected

if (userGuess1 == ran1 || userGuess1 == ran2 || userGuess1 == ran3 || userGuess1 == ran4)

numbersMatched++;

if (userGuess2 == ran1 || userGuess2 == ran2 || userGuess2 == ran3 || userGuess2 == ran4)

numbersMatched++;

if (userGuess3 == ran1 || userGuess3 == ran2 || userGuess3 == ran3 || userGuess3 == ran4)

numbersMatched++;

if (userGuess4 == ran1 || userGuess4 == ran2 || userGuess4 == ran3 || userGuess4 == ran4)

numbersMatched++;

// This will check the order of the numbers that are input by the user

if (temporary1 == temporaryGuess1 && temporary2 == temporaryGuess2 && temporary3 == temporaryGuess3 && temporary4 == temporaryGuess4)

inOrder = true;

// This will determine the amount the user has won depending on the numbers input and order

int amountWon = 0;

if (numbersMatched == 0)

amountWon = 0;

if (numbersMatched == 1)

amountWon = 10;

if (numbersMatched == 2)

amountWon = 30;

if (numbersMatched == 3)

amountWon = 100;

if (numbersMatched == 4 && inOrder == false)

amountWon = 1000;

if (numbersMatched == 4 && inOrder == true)

amountWon = 10000;

// This will be the output display for the results

Console.WriteLine("\nResults:");

Console.WriteLine("\nRandomly generated numbers:" + temporary1 + "" + temporary2 + "" + temporary3 + "" + temporary4);

Console.WriteLine("\nUser Guesses:" + temporaryGuess1 + "" + temporaryGuess2 + "" + temporaryGuess3 + "" + temporaryGuess4);

Console.WriteLine("\nTotal numbers that matched:" + numbersMatched);

Console.WriteLine("\nTotal amount won: $" + amountWon);

Console.ReadLine();

}

}

}
