Question 1

Each programming language has a few reserved ____________________ that are not allowed as variable names because they are part of the language's syntax.

Accepted Answer

The answer of Each programming language has a few reserved...

Question 2

____ is the process of paying attention to important properties while ignoring nonessential details.

Accepted Answer

Abstraction is the concept in computing and mathematics where attention is focused on important properties of an object or system while ignoring nonessential details. This process is fundamental in reducing complexity and allowing for focus on higher-level ideas.

Question 3

When a program has several modules calling other modules,programmers often use a program ____,which operates similarly to an organizational chart,to show the overall picture of how modules are related to one another.

Accepted Answer

A hierarchy chart, also known as a structure chart, visually represents the relationships between different modules within a program, illustrating how they call upon one another, much like an organizational chart does for company structure.

Question 4

A(n)____ is similar to a variable,except it can be assigned a value only once.

Accepted Answer

Named constants are similar to variables but are assigned a value only once, typically at the time of declaration, and their value cannot be changed throughout the program.

Question 5

Match each term with a statement below.

-Named memory locations whose contents can vary or differ over time

Accepted Answer

Variables are named memory locations whose contents can change or vary over time, allowing for the storage and manipulation of data values in a program.

Question 6

A ____ variable is not used for input or output,but instead is just a working variable that you use during a program's execution.

Accepted Answer

A temporary variable is used within a program for intermediate calculations or storage of information during execution, not for input or output purposes.

Question 7

Program ___________________ are written explanations that are not part of the program logic but that serve as documentation for readers of the program.

Accepted Answer

The answer of Program ___________________ are written explanations that are...

Question 8

Programmers say the statements that are contained in a module have been ____.

Accepted Answer

Encapsulation is a fundamental concept in programming where the details of how a module or object operates are hidden from the rest of the program, only exposing what is necessary. This is why programmers say the statements in a module have been encapsulated.

Question 9

Programmers refer to programs that contain meaningful names as ____.

Accepted Answer

Self-documenting programs use meaningful names for variables and functions, making the code easier to understand without additional comments or documentation.

Question 10

Programmers say that variables and constants declared within a module are ____ only within that module.

Accepted Answer

Variables and constants declared within a module are considered "in scope" only within that module, meaning they can only be accessed and used within the confines of that module.

Question 11

Depending on the programming language being used,modules are also known as ____ .

Accepted Answer

Modules in programming can be referred to as subroutines, procedures, or methods, depending on the language and context. These terms are commonly used interchangeably to describe blocks of code designed to perform a specific task.

Question 12

As programs become larger and more complicated,the need for good planning and design ____ .

Accepted Answer

As programs grow in size and complexity, the importance of thorough planning and design becomes more critical to ensure the program's functionality, maintainability, and scalability.

Question 13

The ____ dictate the order in which operations in the same statement are carried out.

Accepted Answer

The rules of precedence determine the order in which operations are performed in a statement, ensuring that operations like multiplication and division are carried out before addition and subtraction, among others.

Question 14

The process of breaking down a large program into modules is called ____.

Accepted Answer

Modularization is the process of dividing a program into separate modules, which can be developed, tested, and debugged independently.

Question 15

The mainline logic of almost every procedural computer program consists of these three distinct parts: ____ .

Accepted Answer

The mainline logic of almost every procedural computer program consists of housekeeping tasks (initial setup), detail loop tasks (the main processing loop), and end-of-job tasks (cleanup and closing operations).

Question 16

___________________ tasks include any steps you must perform at the beginning of a program to get ready for the rest of the program.

Accepted Answer

The answer of ___________________ tasks include any steps you must...

Question 17

In a flowchart,an ____ is most often represented by a three-sided box that is connected to the step it references by a dashed line.

Accepted Answer

An annotation symbol in a flowchart is used to add explanatory notes or comments and is typically represented by a three-sided box connected by a dashed line.

Question 18

____ variables and constants are known to the entire program.

Accepted Answer

Global variables and constants are accessible throughout the entire program, making them known to all parts of the program. Local variables, in contrast, are only accessible within the function or block in which they are declared.

Question 19

Whole number variables are known as ____________________ variables.

Accepted Answer

The answer of Whole number variables are known as ____________________...

Question 20

Declaring a starting value is known as ____________________ the variable.

Accepted Answer

The answer of Declaring a starting value is known as...
