Programming Concepts - Algorithms with array

What is a variable in programming?

• A series of instructions designed to solve a problem

• A unique identifier of an address in memory that holds a value

• A data structure that stores multiple values

• An expression that equates to true or false

Which of the following is a data structure that stores multiple values in a single variable?

• Algorithm

• Element

• Array

• Condition

What is an algorithm?

• A value stored within a data structure

• A position number in a data structure

• A series of instructions designed to solve a specific problem

• A loop that repeats until a condition is met

What does a data structure do?

• Organises and stores data for efficient access

• Specifies a variable before using it

• Equates an expression to true or false

• Repeats steps until a condition is met

What is an element in the context of data structures?

• A unique identifier of an address in memory

• A value that is stored within a data structure

• A series of instructions designed to solve a problem

• An expression that equates to true or false

What is the role of an index in a data structure?

• To specify a variable before using it

• To store data for efficient access

• To indicate the position number in a data structure

• To loop until a condition is met

What does 'contiguous' mean in the context of data storage?

• Elements are stored next to each other in memory

• A series of instructions designed to solve a problem

• An expression that equates to true or false

• A value stored within a data structure

What is a definition of iterate?

• To skip certain steps in a process to speed it up

• To complete a task only once without repeating it

• to loop/repeat step by step until a condition is met

• To reverse a sequence of actions and go back to the start

A condition in programming is ...

• a fixed value that never changes during programme execution

• an expression that equates to true or false

• a command that runs a function immediately without checking anything

• a loop that repeats indefinitely without stopping

What does declaring a variable mean?

• Reserving memory space that automatically deletes itself after one use

• Creating a fixed value in the programme that cannot be changed later

• Writing a condition that determines whether a variable exists

• Specifying a variable, or data structure before using it
