Question 1

Case 1

You have just starting working at Quantum Company. As a new programmer, you have been asked to review and correct various pseudocode.

-There is a method with the header: void printData(num x,string y).There is a declared numeric variable: test.Which of the following is a correct method call?
A) printData(test)
B) printData(test,"Good")
C) printData("Good",test)
D) printData("Good","Best")

Accepted Answer

The method requires two inputs, a numeric value for the first parameter and a string for the second parameter. Option A only provides one parameter, while options C and D switch the order of the parameters. Option B correctly provides both required parameters with the correct data types.

Question 4

Case 1

You have just starting working at Quantum Company. As a new programmer, you have been asked to review and correct various pseudocode.

-The following pseudocode is not working correctly.The code should multiply price and tax,and display the result.What code needs to be corrected? computeArea(num width,num length)
Declarations
Num result
Width * length
Output "The area is " result
Return
A) Change the return statement to
Return result
B) Change the result initialization to
Num result = width * length
C) Change the return statement to
Return output
D) Change the output line to
Output = width * length

Accepted Answer

The variable "result" needs to be initialized with the product of "width" and "length". Therefore, option B is the correct choice as it initializes "result" to the correct value. Option A is partially correct but alone it wouldn't solve the problem. Option C is incorrect because there is no "output" variable declared. Option D is incorrect because it assigns the product of "width" and "length" to an undeclared variable "Output" instead of displaying it.

Question 5

Case 1

You have just starting working at Quantum Company. As a new programmer, you have been asked to review and correct various pseudocode.

-The following pseudocode is not working correctly. What code needs to be corrected? This is the call to the method: displayName()
And this is the method:
DisplayName(string name)
Output "My name is " name
Return
A) Change the method call to
DisplayName("Sean")
B) Change the method call to
DisplayName(Sean)
C) Change the return statement to
Return output
D) Change the return statement to
Return name

Accepted Answer

The method call needs to have a string parameter passed as an argument enclosed in double quotes. Choice A does this correctly, passing the string "Sean" as an argument. Choice B is incorrect because it does not enclose the parameter in quotes, so the code will not compile. Choices C and D are also incorrect because there is no variable named "output" in the method, and the desired output is to display a message with the name parameter, which is correctly returned by the original code.

Question 6

Case 1

You have just starting working at Quantum Company. As a new programmer, you have been asked to review and correct various pseudocode.

-The following pseudocode is not working correctly.The code should add price and tax.What code needs to be corrected? num computeSum(num price,num tax)
Declarations
Num result
Result = price + tax
Return
A) Change the result calculation to
Result = tax + price
B) Change the result calculation to
Result = (price + tax)
C) Change the return statement to
Return num
D) Change the return statement to
Return result

Accepted Answer

The calculation for the sum of price and tax is correct, and simply needs to be enclosed in parentheses to ensure correct order of operations. Additionally, the return statement should specify that the function should return the calculated result. Therefore, the correct choices are D for changing the return statement to "Return result".

Question 7

Case 1

You have just starting working at Quantum Company. As a new programmer, you have been asked to review and correct various pseudocode.

-There is a method with the header: void printData(num x,string y). There is a declared a numeric variable: test. What does this method return?
A) a numeric and a string variable
B) test
C) nothing
D) it depends on the parameters

Accepted Answer

The method has a return type of "void", which means it does not return anything. The presence of the numeric variable "test" does not affect the return type of the method.

Question 8

Write the pseudocode for the method named computeSum.The method should return a numeric value: result.The method should have two numeric parameters: amount1 and amount2. result is equal to the sum of amount1 and amount2.
