Question

- Part 2 – 4 Desk Checking Exercises – these are 3 programs (pseudocode) that are working and 1 program (Python). Explainthe intent of the pseudocode / program. If you use test data, note the test data.  .  You are NOT trying to find mistakes.

Use this textbox to explain the pseudocode/ code intent. Include any test data used:

What does this do? Desk Checking #4:  Explain the intent of this code.  Be as specific as possible.  
List the data you use for example data.

import random

number = random.randint(1, 10)

keepGoing = input("Do you want to guess a number? Enter Y or N ")

while (keepGoing != "Y") and (keepGoing != "N"):

    keepGoing = input("Invalid Response." + " Please type Y or N. ")

while keepGoing == "Y":

    

    stringNumber = input("I'm thinking of a number. .\n Try to guess by entering a number between 1 and 10 ")

    userNumber = int(stringNumber)

    

    while (userNumber < 1) or (userNumber > 10):

        stringNumber = input("Number must be in the range of 1 to 10: Please try again: ")

        userNumber = int(stringNumber)

    if userNumber == number:

        keepGoing = "N"

        print("You are a genius. That's correct!")

    else:

        keepGoing = input("That's not correct. Do you want to guess again? Enter Y or N ")

        

        while (keepGoing != "Y") and (keepGoing != "N"):

            keepGoing = input("Invalid Response." + " Please type Y or N. ")

Answer 1

The program imports the module random at first inorder to use the random function.Using the random function a number between 1 to 10 is generated and this is stored in the variable number. This arguments of the random function is the range.Here it is 1 to 10.This is assigned to number

lets assume number=4

Then the screen prompts the user with the following message

Do you want to guess a number?Enter Y or N

if the user inputs anything other than Y or N then the following message is displayed.

Invalid Response. Please typeY or N.

if the user inputs Y then the following steps are executed.(This is checked using the while loop.)

following message is displayed on the screen.

I'm Thinking of a number..

Try to guess a number between 1 and 10.

example : if it is 4

usernumber=4

while loop is checked to see if usernumber<1 or usernumber>10.(displays Number must be in the range of 1 to 10 .try again)here the condition is not satisfied.

checks if usernumber=number(checks if usernumber = system generated number)

here it is satisfied 4=4

so displays You are a genius.That's correct!

else the message displays as That's not correct. Do you want to guess again?Enter Y or N.

if it is Y then the above steps are executed.Else

if the user inputs anything other than Y or N then the following message is displayed.

Invalid Response. Please typeY or N.

if it is N then program Ends
