What is a data structure?

• A type of software used for data analysis

• A way of organising and storing data

• A programming language

• A type of computer hardware

Which of the following is a characteristic of an array?

• It can store data of different types

• It is a collection of elements identified by index or key

• It is used to store a single value

• It is a type of loop in programming

What is a record in the context of data structures?

• A collection of fields, possibly of different data types, typically in a fixed number and sequence

• A single data point in a database

• A type of loop used in programming

• A method for sorting data

Which of the following is a string manipulation technique?

• Sorting an array

• Concatenating two strings

• Generating a random number

• Declaring a variable

What is the purpose of random number generation in programming?

• To create predictable outcomes

• To generate a sequence of numbers that cannot be predicted logically

• To sort data in a specific order

• To store data in a database

What is a subroutine in programming?

• A type of data structure

• A sequence of program instructions that perform a specific task, packaged as a unit

• A method for sorting data

• A type of loop used in programming

What is the role of parameters in subroutines?

• To store data permanently

• To pass information into a subroutine

• To generate random numbers

• To concatenate strings

What is a local variable?

• A variable that is accessible throughout the entire program

• A variable that is only accessible within the block of code or subroutine in which it is declared

• A variable that stores data permanently

• A variable that is used to generate random numbers

What does a structured approach to programming involve?

• Writing code without any specific plan

• Organising code into small, manageable sections or modules

• Using only one programming language

• Avoiding the use of subroutines

Which of the following is an example of using a structured approach in programming?

• Writing all code in a single function

• Dividing a program into functions and modules

• Using only global variables

• Avoiding the use of comments in code
