Question

This is a question I couldent get very far on using Micrsoft Visual Basic rearding Arrays. Plasea answer in English, Thank you.

1. Create a VB Form with a single button to start the game. When the user clicks the button, do the following:

2. Create an array of 10 random integers, each between 0 and 30, inclusive. Hints: use a loop, and it is OK if some of the elements of the array may hold the same number.

3. Enter the 'Game loop':

(The user has 3 attempts to guess a winning number.)

Hint: the condition for your loop needs to include both a counter for the number of attempts and a boolean for whether the user has made a correct guess or not

a. Ask the user for their guess using an InputBox

b. Call a function to search the array you created in step 2 for the number the user gave.

c. If your search function returns true, tell the user they won the game and stop looping, otherwise, continue looping until the user either runs out of guesses or wins the game

3. Your search function must take two parameters, the array holding the random numbers and the user's guess (an integer) and must do the following:

a. Look through each element of the array

b. if the array element matches the users guess return true

c. if you go clear through the loop and do not get a match, return false

Explanation / Answer

open visual basic application

and select the vb form and name it as Guess in the properties window

Drag a button on the Guess form and settext as "Start Game" , name as “ startButton” in text properties window,

double click on start button and enter the following code

Private Sub startButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles startButton.Click

'declaring necessary variables

        Dim randomNums(10) As Integer

        Dim userGuess As Integer

        Dim numAttempts As Integer

        Dim madeCorrectGuess As Boolean

        Dim myValue As String

        Dim RandomClass As New Random() 'for generating random number

        startButton.Visible = False

        'generating 10 random numbers between 0 to 30

        For i = 0 To 9

            randomNums(i) = RandomClass.Next(0, 30)

        Next

        'initialize the varaibles

        numAttempts = 0

        madeCorrectGuess = False

        'eneter into Game loop

        While numAttempts < 3 And madeCorrectGuess = False

            myValue = InputBox("Guess a number(0-30): number of attempts available:" + Convert.ToString(3 - numAttempts), "Guess ", "-1")

            userGuess = Convert.ToInt16(myValue)

            'each time call search function

            If search(userGuess, randomNums) Then

                madeCorrectGuess = True

            End If

            numAttempts = numAttempts + 1

        End While

        'display the result

        If madeCorrectGuess = True Then

            MessageBox.Show("Congrats! You win", "Guess Game Result")

        End If

        If numAttempts >= 3 Then

            MessageBox.Show("Sorry! try again", "Guess Game Result")

        End If

    End Sub

9. now create a user defined function in the class Guess

Public Function search(ByVal guess As Integer, ByVal randoms() As Integer)

        For i = 0 To 9

            If randoms(i) = guess Then

                Return True

            End If

        Next

        Return False

    End Function
