Question 1

If you have more than five to six statements that are closely related to the same purpose and have the potential of being used in more than one place in your program, you should consider turning these statements into a module.

Accepted Answer

Grouping related statements into a module promotes code reuse and improves maintainability by encapsulating functionality that can be easily imported and used in different parts of a program.

Question 2

Modules cannot be reused in a program.

Accepted Answer

Modules are designed to be reusable components in programming, allowing for the same code to be used in multiple parts of a program or in different programs without modification.

Question 3

Programmers can work on separate modules for efficiency without having to worry about variable names used in other modules.

Accepted Answer

This is because variables in one module are typically not visible in another module unless explicitly imported or shared, allowing programmers to work independently without name conflicts.

Question 4

An advantage of modularization is that the main module is easier to understand yet still gives the "big picture" of what's happening.

Accepted Answer

Modularization breaks down a program into smaller, manageable sections (modules), making the main module more straightforward and focused on the overall flow, thus easier to understand while still presenting the comprehensive functionality of the program.

Question 5

In a pseudocode class definition, if a method returns a value, the method header starts with the method name

Accepted Answer

In a pseudocode class definition, if a method returns a value, the method header typically starts with the return type or a keyword indicating it will return a value, not directly with the method name.

Question 6

A(n) ____ is simply a section of a program that performs a specific task.

Accepted Answer

A module is a section of a program designed to perform a specific task, often encapsulated to be reused in different parts of the program or even in different programs. Constants, arguments, and parameters are different concepts related to values and data passed within or between functions and modules, but they do not describe sections of a program designed to perform tasks.

Question 7

Instead of listing all the code in the main program, your main program calls the ____.

Accepted Answer

The main program calls the module, which is a piece of program code that performs a specific function and can be called upon by the main program or other modules.

Question 8

____ is used to create a program's overall outline and describe tasks to be accomplished, and then details of these tasks are refined later.

Accepted Answer

Top-down design is a method where the overall structure of a program is outlined first, and then the specifics of each part are developed. This approach helps in breaking down a large problem into smaller, more manageable parts.

Question 9

When output is meant for the screen, you should use the ____ keyword.

Accepted Answer

The answer of When output is meant for the screen,...

Question 10

When output is meant for a printer, you should use the ____ keyword.

Accepted Answer

The correct keyword for directing output to a printer in many programming contexts is "Print." This command is used to send data to the output device, which can be a printer in this context.

Question 11

____ are created when a module is called and exist only while statements in the module are performed.

Accepted Answer

Local variables are created within a module (or function, method, etc.) and exist only for the duration of that module's execution. They are not accessible outside the module in which they are declared.

Question 12

With modular programming, a variable's ____ is the section of program code in which a variable can be accessed.

Accepted Answer

The scope of a variable refers to the part of a program where the variable can be accessed or used. It defines the visibility of a variable within different parts of a program.

Question 13

____ are available to all modules in the program.

Accepted Answer

Global variables are accessible from any part of the program, making them available to all modules within that program. Local variables, arguments, and parameters have scope limitations.

Question 14

In the code below, why is it that the displayName() module cannot print the person's name?
Start
Call getInput()
Call displayName()
Stop
Module getInput()
Declare String name
Display "Enter your name: "
Input name
End Module
Module displayName()
Display "Your name is: " + name
End Module

Accepted Answer

The name variable is declared within the getInput() module, making it local to that module. Therefore, it is not accessible in the displayName() module, which is why the displayName() module cannot print the person's name. This is an issue of variable scope.

Question 15

In which of the following is the variable name declared as a global variable?

Accepted Answer

In option D, the variable "name" is declared outside of any module, at the start of the program, making it a global variable accessible by all parts of the program.

Question 16

Why is it that all variables are not declared as global?

Accepted Answer

Local variables allow for modular programming, where programmers can work on separate modules without worrying about variable name conflicts with other parts of the program. This independence is crucial for managing complex projects efficiently.

Question 17

What happens if a module uses a local variable with the same name as a main module variable, which is assumed to be global?

Accepted Answer

When a module uses a local variable with the same name as a global variable, the local variable shadows the global variable within the module's scope. This means that any reference to the variable name within the module will refer to the local variable, not the global one.

Question 18

____ are values represented as constants or variables, which are enclosed in the parentheses following the module name in the Call statement.

Accepted Answer

Arguments are the values passed to a function or module, enclosed in parentheses, following the module name in a call statement.

Question 19

Which of the following statements is true?

Accepted Answer

The answer of Which of the following statements is true?
...

Question 20

Sending the value of a variable or constant to a module, where a local variable is initialized to the argument's value is known as ____.

Accepted Answer

Passing by value involves sending a copy of the value of an argument to the receiving function, where a new local variable is created with this value. This means changes to the variable inside the function do not affect the original variable.
