True/False (10)
1. The word disk is often used to refer to any storage device.
Answer: true
2. In the program development cycle, the first step in writing instructions to carry out a task is to determine how to process the input to obtain the desired output.
Answer: false

3. Pseudocode is typically more compact than a flowchart.
Answer: true

4. In a hierarchy chart, details on how modules work should be included.
Answer: false

5. The main benefit of hierarchy charts is in the initial planning phase of a program.
Answer: true

6. Flowcharts are time-consuming to write and difficult to update.
Answer: true

7. Python requires all programs be saved as a file on a storage device before they can be executed.
Answer: true

8. Indentation is not semantically meaningful in Python.
Answer: false

9. Python is considered a block-structured language.

Short Answer (9)
1. Most programs do three general things. List them.
Answer: Take in data, manipulate data, and produce desired results. This is also called input, processing and output.
2. Someone preparing for a marathon trains by running laps on a track which is ¼ mile per lap. The runner would like to know their average time in minutes per mile. List the inputs, processing steps and output for a computer program to accomplish this.
Answer: The input is the number of laps and the total time run in minutes. The processing is dividing the laps by 4 to give the miles run, then dividing the time in minutes by the miles. The output is the minutes per mile calculated.
3. Fill in the steps of the problem solving process.

Answer:

4. List the 5 steps in the software development life cycle in order.
Answer:
1) analyze
2) design
3) code
4) test and correct
5) complete the documentation
5. You are given the following pseudocode to determine if a number is even or odd. Create a hierarchy chart for this program.

get number
If the number is divisible by 2 without a remainder
display the number is even
else
display the number is odd

Answer:

6. You are given the following pseudocode to determine if a number is even or odd. Create a flowchart for this program.

get number
If the number is divisible by 2 without a remainder
display the number is even
else
display the number is odd

Answer:

7. Given the following flowchart for a program that determines if a number is even or odd, write the pseudocode.

Answer:
get number
If the number is divisible by 2 without a remainder
display the number is even
else
display the number is odd

8. Write a line of Python code that displays the sum of 468 + 751.
Answer: print (468 + 751)
