Q: You should test an algorithm with invalid data because users sometimes make mistakes when entering data.

Q: You can only perform a desk-check using an algorithm's pseudocode.

Q: It is helpful to use a desk-check table when desk-checking an algorithm.

Q: Before you begin the desk-check, you first choose a set of sample data for the input values, which you then use to manually compute the expected output values.

Q: Desk-checking is also called pencil-tracing, because the programmer uses a pencil and paper to follow each of the algorithm's instructions.

Q: Not all algorithms require a processing item.

Q: For simple algorithms, flowcharts work just fine.

Q: When planning an algorithm, you need to create both a flowchart and pseudocode.

Q: Visio is a flowcharting program.

Q: You can draw the flowchart symbols by hand; or, you can use the drawing or shapes feature in a word processor.

Q: Unlike a flowchart, pseudocode uses standardized symbols to visually depict an algorithm.

Q: Pseudocode is standardized.

Q: To avoid confusion, it is important that the algorithm is consistent when referring to the input and output items.

Q: Display, print, and store refer to a file on disk, the printer, and the computer screen, respectively.

Q: Most algorithms end with an instruction to print, display, or store the output items.

Q: Most algorithms begin with an instruction that enters the input items into the computer.

Q: Each instruction in the algorithm should start with a noun since it will describe an action that the computer needs to take.

Q: If you are having trouble analyzing a problem, try reading the problem specification several times, as it is easy to miss information during the first reading.

Q: Analyzing real-world problems is generally as easy as analyzing the problems found in a textbook.

Q: When determining the output, it helps to think about the information that you would need to solve the problem manually.

Q: The input typically is stated as nouns and adjectives in the problem specification.

Q: When analyzing a problem, you always search first for the input, and then for the output.

Q: The two most important components of any problem are the problem's output and its input.
