What happens in the flowchart when the end of the list is reached without finding the search term?

The search term is added to the list

What is a variable in computer programming?

A named location in memory that stores data and can be changed

Which of the following is NOT a benefit of using constants in programming?

Constants can be changed frequently

No need to repeatedly type the same value

They make programs more readable

The value only needs to be altered in one place

How is a variable used in a computer's memory?

It takes possession of a memory box and stores data

It stores an unchangeable value

It assigns a unique address to each data type

What does the term "scope" refer to in programming?

The region of the code where a variable can be accessed

The time period a variable exists

The size of the variable in memory

The number of functions that can access the variable

What is the lifetime of a local variable?

The time from its creation to its deletion from memory

The duration it is stored on the disk

The scope within the function it is declared

The length of the program execution

Why does the code produce an error?

Because the variables are local to the subroutine and cannot be accessed from the main block

Because the variables are not initialized

Because the variables are global

Because the function is not called correctly

What is the scope of global variables in a program?

They are available to all parts of the program.

They are only available within the function they are declared in.

They are available only within the file they are declared in.

They are available only to the operating system.

How long do global variables exist in a program?

As long as the program is running.

Only while a function is executing.

Only during the execution of the file they are declared in.

Indefinitely, even after the program has terminated.

What is a subroutine in programming?

A named block of code that performs a specific task

Which of the following best describes a procedure in programming?

A subroutine that does not return any information to the main program

A subroutine that returns a value

A loop that executes indefinitely

What is the purpose of the 'procArea' procedure shown in the example?

To calculate the volume of a cube

To determine the perimeter of a rectangle

What is a function in programming?

A subroutine that returns a value to the main program or calling function.

A set of instructions that performs a task and does not return a value.

A data structure that stores variables.

A type of programming language.

Where is the result of the function 'funcArea' stored in the given example?

Directly printed to the console.

What is a parameter in the context of a procedure or function?

C) Data that is passed to a procedure or function for it to use

A) A type of function that returns no values

B) A variable that stores temporary data

D) A method that modifies data within a function

How is a parameter passed by value?

B) A copy of the data is created and passed to the procedure

A) The original data is directly manipulated within the procedure

C) The data is stored externally and referenced by the procedure

D) The parameter is passed as a reference to the original data

What happens to the original data when a parameter is passed by value?

C) It remains unaffected by any changes in the procedure

A) It is permanently altered by the procedure

B) It is enhanced with additional data

D) It is deleted after the procedure completes

What does it mean to pass a parameter by reference in a procedure?

The procedure receives the address of the parameter, allowing the data to be changed.

The procedure receives a copy of the parameter's value.

The procedure receives the original data type of the parameter.

The procedure makes the parameter immutable.

What is a potential downside of passing parameters by reference?

It can lead to unintended side effects if the parameter's value is changed.

It speeds up the execution of the program.

It prevents the parameter from being used in other procedures.

It simplifies the debugging process.

What is the purpose of using meaningful identifiers in self-documenting code?

To make the code more readable and understandable

To increase the processing speed of the code

To reduce the number of lines in the code

To enhance the color scheme of the code editor

According to the text, what should be avoided to make code self-documenting?

Declaring variables at first use

What is recommended about variable declaration in self-documenting code?

Declare variables at the end of the program

Declare all variables in a single line

How should the layout of code be considered for self-documenting purposes?

It should be consistent throughout the code

It should be inconsistent to keep the reader alert

It should be colorful and use different fonts

It should vary depending on the programming language

What is the primary benefit of laying out code in a readable format as demonstrated in the image?

It helps in maintaining the code more easily.

It changes the functionality of the code.

It reduces the amount of code written.

According to the image, what happens when the code is poorly laid out?

It makes maintaining the code more challenging.

It prevents the code from running.

It enhances the code's performance.

What is recursion in programming?

The ability of a subroutine or program module to call itself.

The process of a function calling another function.

The process of iterating through data structures.

What is necessary to prevent a recursive function from causing an infinite loop?

A return statement outside the recursion

Multiple function calls within the recursion

What is a standard module in programming?

A module that carries out a common task and is used in many different programs.

A module that is used for unique tasks in specific programs.

A module that is rarely used and not well-tested.

A module that is only used in mathematical calculations.

Why is there no need to write a standard module again?

Because it has already been written and decreases development time.

Because it is less efficient than new modules.

Because it is more error-prone than new modules.

Which of the following is a likely benefit of using standard modules?

They are less likely to have errors because they have been tested.

They are more likely to have errors.

They are less likely to be of high quality.

They require more time to integrate into new programs.

What does data compression mean in the context of computer files?

Reducing the amount of file space a file occupies

Increasing the file size for better quality

Encrypting the file for security purposes

Converting the file to a different format

How is the compression ratio of a file calculated?

Compressed file size divided by the original file size

Original file size divided by the compressed file size

Compressed file size multiplied by the original file size

Sum of the original and compressed file sizes

What is the primary characteristic of lossy data compression?

It removes data to reduce the file size.

It enhances the original data quality.

It allows exact recovery of the original data.

It is mainly used for text data compression.

Why is lossy compression not recommended for critical data such as text?

It cannot be decompressed to yield the exact original data.

Which of the following is a common use of lossy compression?

Compressing digitally sampled analogue data like sound and video.
