• Your winnings were more than the largest number the bank’s computers could hold, so an overflow error will occur.

• Since decimal numbers are stored imprecisely in computers, a rounding error will occur.

• The amount will be represented in machine code format, so converting it to decimal will show the balance in a more readable format.

• The amount will cause a runtime error.

• The cash register DISPLAY procedure has an error.

• A rounding error occurred.

• It’s displaying the change owed in a different currency.

• The amount is represented as a string field rather than a number.

You are assigned a parking space in a large parking lot by an automated machine. You recognize that the parking space number is displayed in binary, but the parking spots are labeled in decimal numbers. Convert the parking space number 10011011 to decimal to know where to park and avoid getting towed.

When designing a web page, you see a color you want to use listed in binary as: 01010000, 11001000, 01111000. Which color is it, given the decimal equivalents (Red, Green, Blue)?

You have to change a program written a year ago by someone else. A sample section of code is below. How could the original program author have helped anyone making changes at a later date? PROCEDURE A (x, y, z) IF x < y { x <- z }

• Provided the original program requirements

• Added a video describing the program design and functionality

• Used procedure and variable names that described their purpose and content

Which statement is NOT true?

• Lower level languages are easier to debug because the language is closest to what the computer executes.

• Higher level languages are easier to debug because the language is closer to natural language.

• Lower level languages provide less abstraction.

• Higher level languages are easier for people to code in because they are more abstract.

A simulation of conditions for a new sensor to be used with self-driving cars is being designed. The pseudocode for the test is below.

When car starts, turn sensor on and set incident_counter to 0 When detect object 3 feet or closer, redirect steering wheel away from object Add one to incident_counter

Which condition is not a useful simulation test for the sensor?

• Multiple obstacles at the same time.

• Zero incidents.

• Set up objects at 3 feet, less than 3 feet, and greater than 3 feet to determine the action taken.

• If the car causes an accident, by swerving.

Which of the following will evaluate to "true"?

i. (true AND true) OR (true AND false)

ii. NOT(true OR false)

iii. NOT(false) AND NOT(true AND false)

• i and ii

• i and iii

• ii and iii

• i, ii, and iii

What outcome will the Boolean conditions in the diagram produce at steps 1, 2, and 3?

• (C) 1—False, 2—True, 3—True

• (A) 1—True, 2—True, 3—False

• (B) 1—False, 2—False, 3—True

• (D) 1—True, 2—False, 3—False
