Computational Thinking and Programming Quiz

What is the main purpose of a flowchart in computational thinking?

• To provide a detailed analysis of historical data

• To create a decorative design for a presentation

• To visually represent the steps and logic of a computational process.

• To calculate complex mathematical equations

What is the difference between an array and a stack in programming?

• Arrays are only used in front-end development while stacks are used in back-end development

• Arrays can only store one type of data while stacks can store multiple types

• Arrays are used for storing data while stacks are used for executing functions

• The main difference is in their underlying principles of operation.

Explain the concept of event-driven programming.

• The flow of the program is determined by events such as user actions, sensor outputs, or messages from other programs or threads.

• It involves manual input from the user to progress the program

• Event-driven programming is based on a fixed sequence of steps

• The program flow is determined by the time of day

What is the role of a mainloop in coding for the web?

• It continuously checks for events and updates the user interface.

• It generates random numbers for the web

• It designs the layout of the web page

• It compiles the code for the web

What is the significance of validation techniques in managing variables?

• Validation techniques have no impact on managing variables

• Validation techniques only apply to certain types of variables

• Validation techniques are only necessary for small datasets

• Validation techniques ensure the accuracy and reliability of variables.

Define the term 'searching algorithm' and provide an example.

• Quick sort algorithm

• Linear search algorithm

• Bubble sort algorithm

• Binary search algorithm

Explain the process of sorting in the context of programming.

• Sorting is the process of arranging elements in a specific order, such as ascending or descending, based on a certain criteria.

• Sorting is the process of removing duplicate elements from a list

• Sorting is the process of multiplying elements in a list by a specific number

• Sorting is the process of randomly shuffling elements in a list

What is a callback function and how is it used in programming?

• A callback function is used in programming to handle asynchronous operations, event handling, and to perform tasks after a certain event or task is completed.

• A callback function is used to format text in programming

• A callback function is used to define variables in programming

• A callback function is used to create loops in programming

Describe the concept of pseudocode and its importance in algorithm development.

• Pseudocode is not important in algorithm development as it is just a waste of time and does not contribute to the actual coding process.

• Pseudocode is a detailed yet readable description of what a computer program or algorithm must do, expressed in a formally-styled natural language rather than in a programming language. It is important in algorithm development as it helps in planning and organizing the logic of the program before actual coding begins.

• Pseudocode is a type of code that is written in a programming language and can be directly executed by a computer.

• Pseudocode is only used by beginner programmers and is not necessary for experienced developers.

How are sets used in computational thinking and programming?

• Sets are used to store unique elements and perform operations like union, intersection, and difference.

• Sets are used to store duplicate elements and perform operations like addition, subtraction, and multiplication.

• Sets are used to store elements in a specific order and perform operations like sorting and filtering.

• Sets are used to store elements in a random order and perform operations like merging and splitting.
