Deck 2: Methods

Question 1

Answer 1

True

Question 2

Answer 2

True

Question 3

Modular development makes a large project more manageable.

Answer 3

True

Question 4

Modular development is slow for large projects.

Question 5

Modular development does not necessarily lead to a higher-quality product.

Question 6

Modular development makes it easier to find and correct errors in computer software.

Question 7

Modular development decreases the reusability of your solutions.

Question 8

Over time, modular development allows you to build libraries of software modules for different tasks.

Question 9

All computer programs, from the lowest levels of an operating system that directly control hardware to the most complex user applications, are made up of layers of short programming modules that are constantly reused in different situations.

Question 10

Often, the hardest part of correcting an error in computer software is finding out exactly what is causing the error.

Question 11

Objects created for one project cannot be reused by other projects.

Question 12

Software design begins by writing clear specifications for what the software is supposed to do.

Question 13

Top-down development and modular design are used from the beginning of the design process and help designers break a complex problem into parts that can be more easily understood.

Question 14

Software testers must develop a testing plan that examines new software under all possible circumstances.

Question 15

Once a method has been integration tested and debugged, it can be unit tested.

Question 16

Alice objects have three kinds of methods.

Question 17

Primitive methods are encapsulated methods.

Question 18

In Alice, user-defined methods are encapsulated.

Question 19

You can use primitive methods and user-defined methods to write new methods of your own.

Question 20

Primitive methods may be used to build more complex methods, or they may be run directly.

Question 21

You can run a primitive method directly by right-clicking an object or an object tile in the Object tree, and then selecting the method you want to run from the list that appears.

Question 22

The first step in creating a new world is to set the scene by opening a template, adding necessary objects, and positioning things.

Question 23

Alice's programming language has two primitive instructions to make an object jump up and down.

Question 24

It is much easier to debug software that is written as small modules, each performing an individual task.

Question 25

Once a method stops running, their values are gone unless they were saved elsewhere.
