Question 3 (1 point)

Question 3) METHODs to our Madness: Use the pseudocode methods below to answer the questions starting on the next page.

FIRST METHOD:

COMMENT parameters should be integers METHOD largestValue(parameters: num1, num2) BEGIN             IF(num1 >= num2) THEN result ← num1 ELSE result ← num2             ENDIF END largestValue

SECOND METHOD:

COMMENT parameters should be doubles METHOD largestValue(parameters: num1, num2) BEGIN             IF(num1 >= num2) THEN result ← num1 ELSE result ← num2             ENDIF             RETURN result END largestValue

THIRD METHOD:

COMMENT parameters should be integers METHOD largestValue(parameters: num1, num2, num3) BEGIN IF(num1 >= num2 AND num1 >= num3) THEN          result ← num1 ELSE IF (num2 >= num3) THEN result ← num2             ELSE result ← num3 ENDIF RETURN result END largestValue

Given the pseudocode methods above and on the previous page,which method corresponds to each of the method calls specified?

What would that method return based on the arguments listed?

If nothing would be returned, please write “NO RETURN” in the box.

A) CALL largestValue(3, 5, 3) - (10 points)

B) CALL largestValue(3, 5) - (10 points)

C) CALL largestValue(3.0, 5.5) - (10 points)

Answer 1

A) largestValue(3,5,3) has 3 arguments which are ints.
Signature of 3rd method is
THIRD METHOD : METHOD largestValue(num1, num2, num3) is invoked

num2>=num3, so, result contains 5. Answer is 5

B) largestValue(3,5) has 2 ints. So, FIRST METHOD will be invoked. It is not returning anything. So, ans is
NO RETURN

C) largestValue(3.0,5.5) has 2 doublts as parameters. so, SECOND METHOD will be invoked. Answer is num2.
So, 5.5
