Question

Question 5 (1 point)

userGuess ← 0, secretNumber ← 5

PRINT “Enter a number between 1 and 10”

READ userGuess

WHILE (userGuess < 1 OR userGuess > 10)
PRINTLINE “That is not between 1 and 10. Try again.”
READ userGuess
ENDWHILE

IF (userGuess == secretNum) THEN
PRINTLINE “That’s right! ”, userGuess, “ is the secret!”
ELSE
PRINTLINE userGuess, “ is not the secret!”
ENDIF

What is the first WHILE loop being used for?

Question 5 options:

	Input validation
	Random number generation
	Comparison between userGuess and secretNum
	Nothing

Question 6 (1 point)

CREATE userChoice ← 0

PRINT “Choose a number to see the multiplication table.”

READ userChoice

FOR (multiplier ← 1, multiplier < 12, multiplier ← multiplier + 1)
PRINTLINE userChoice, “ * “, multiplier, “ = “, (multiplier * userChoice)
ENDFOR

Why was a FOR loop used for this example?

Question 6 options:

	Number of loop iterations was known
	Number of loop iterations was random
	A WHILE loop would not work in this example.
	A DO...WHILE loop would not work in this example.

Question 7 (1 point)

CREATE operation ← “”, number ← 0

WHILE (operation NOT EQUAL ”Q”)

    PRINT (“Enter an operation: A, S, M, D, Q”)

    READ operation

    SWITCH (operation)

    CASE ‘A’

DO

    PRINT (“Number to add (0 to quit):”)

    READ number

    total += number

    PRINTLINE total

WHILE (number <> 0)

BREAK

    CASE ‘D’

DO

    PRINT (“Number to divide (0 to quit):”)

    READ number

    total /= number

    PRINTLINE total

WHILE (number <> 0)

BREAK

    DEFAULT

PRINTLINE (“Invalid choice!”)

END WHILE

What mathematical operation would be called if a user enters 'A'?

Question 7 options:

	Subtraction
	Addition
	Division
	Multiplication

Question 8 (1 point)

CREATE sum ← 0, value ← 0, count ← 0

PRINT “Enter an integer (0 to quit)”

READ value

WHILE(value != 0)
count ← count + 1
sum ← sum + value
PRINTLINE “The sum so far is “ + sum.”
PRINT “Enter another integer (0 to quit)”

READ value
ENDWHILE

IF (count == 0) THEN
PRINTLINE “No values were entered.”
ELSE
PRINTLINE “The sum of all values is “ + sum
PRINTLINE “The average of all values is “ + sum/count

ENDIF

What is 0 being used as for the WHILE loop?

Question 8 options:

	Sentinel Newspaper
	Sentinel value
	Sequential value
	Serial value

Question 9 (1 point)

METHOD MAIN ()
    BEGIN
       CREATE result ← SUM(arguments: 1,10)
       PRINT("Sum from 1 to 10 is:”, result)
    
       result ← SUM(arguments: 20,30)  
       PRINT("Sum from 20 to 30 is:”, result)
    
       result ← SUM(arguments: 35,45)  
       PRINT("Sum from 35 to 45 is:”, result)
END MAIN ()
  
METHOD SUM(parameters: num1, num2)
    BEGIN
       CREATE sum ← 0
       FOR (i ← num1, i <= num2, i ← i+1 )
         sum ← sum + i
       ENDFOR
       RETURN sum
END SUM

This METHOD is used to:

Question 9 options:

	Sum values between the two parameters sent to it.
	Subtract the second value from the first value.
	Multiply values sent to it.
	Divide the first value by the second value.

Question 10 (1 point)

METHOD MAIN ()
BEGIN
    CREATE i ← 5
    CREATE j ← 2
    CREATE k ← max(i, j)

    PRINT("The maximum of ", i , " and ” , j ," is ", k)
END MAIN ()

METHOD MAX(parameters: num1, num2)
BEGIN
    CREATE result
    if (num1 > num2)
       result ← num1
    else
       result ← num2
   
    RETURN result
END MAX

What would this method call return?

CREATE num1 = MAX(42,20)

Question 10 options:

	42
	22
	62
	20

Answer 1

Answer:
5) The correct answer is A)input validation
The first while will validate the userGuess input. The UserGuess value should be between 1 and 10.

6)The correct answer is A) Number of loop iterations was known
We know that the loop iterations and we used for loop there.

7)The correct answer is B)Addition
For Case A, The addition operation is performed. First, it will ask for user input and adds the number to the total.

8)The correct answer is D)Serial Value
Zero in while loop used as the serial value to continue to loop until the value becomes Zero.

9)The correct answer is A)Sum Values between the two parameters sent to it
The Sum Method will do Addition operation inside the Method. It will add the two parameters sent.

10)The correct answer is A)42
In the Max Method, an if condition will be checked whether num1 is greater than num2. If this condition is satisfied then the result will be assigned value of num1. Max (42,20) satisfies if condition and num1 will be assigned to result and result will be printed which is 42.

Let me know in case if you have any doubts. Thanks and all the best.
