Santiago Unit 6 Quiz

A school is developing a program to keep track of information about students and their class schedules. In which of the following instances would a data abstraction be most helpful?

• The program includes individual variables to store the names of each student rather than a single list of students.

• A program includes multiple comments that could be combined into a single comment

• A program includes repeated programming statements that could be moved inside a loop

• A program includes repeated code that could be moved inside a function.

You're developing a program to manage information about students and their class schedules at a school. Which data abstraction would be most helpful to simplify and organize this data efficiently?

• • A. Individual variables for each student's name (e.g., name1, name2, ...)

• • B. A single list to store all student names

• • C. Multiple comments combined into a single comment

• • D. Repeated code sections moved inside a function

Your program needs to store not only student names, but also their grades, schedules, and other information. How would you use data abstraction to manage this data effectively?

• • A. Create a single list to store all student information mixed together.

• • B. Use separate lists or other data structures for different types of information.

• • C. Combine data from multiple lists into a single variable for each student.

• • D. Use individual variables for each piece of information about each student.

You need to calculate students' average grades in multiple classes. Which data abstraction technique would help you write reusable code?

• • A. Copy and paste the calculation code multiple times for each class.

• • B. Write a separate function for each class to calculate the average grade.

• • C. Define a general function that can calculate the average grade for any class.

• • D. Create a global variable to store the average grade for all classes.

Your program gets complex as you add more features. What data abstraction technique can help you manage the overall structure effectively?

• • A. Do not Break down the code into functions .

• • B. Use large, all-encompassing functions that handle multiple tasks at once.

• • C. Organize the code into function and label and name variables .

• • D. Keep the code as simple as possible, avoiding any abstractions.

wordList is a list of words that currently contains the values ["tree", "rock", "air"]

• 
  insertItem(wordList, 0, "air")

• wordList[2] = wordList[0]

• removeItem(wordList, 0)
