Programming L2

Imagine Sophia, Lily, and Arjun are working on a computer programming project to create a new app. What strategies might they use in solving problems they encounter during development?

• Designing and testing a hypothesis

• Following a set of rules or instructions

• Planning a strategy, designing and testing a hypothesis

• Using logic to locate and solve errors

Answer explanation

The correct strategy used in problem solving related to computer programming involves planning a strategy, designing, and testing a hypothesis.

Imagine Lily is writing a program to organize her bookshelf. What is an "algorithm" in this context?

• A type of programming error

• A set of rules or instructions for sorting books according to their genre and author

• A strategy used in problem solving

• A form of testing to debug errors

Answer explanation

An algorithm is a set of rules or instructions for performing a task or problem solving, making it the correct choice.

While working on a project, Arjun encounters several errors. How many types of programming errors are there, and what are they?

• Two: syntax and logic errors

• Three: logic, syntax, and runtime errors

• Four: logic, syntax, runtime, and semantic errors

• One: syntax errors

Answer explanation

The correct answer is Three: logic, syntax, and runtime errors. These are the three main types of programming errors that can occur during software development.

During a software development project, Arjun, Nora, and Benjamin are tasked with identifying and fixing bugs in their code. Which forms of testing should they use to locate and debug these programming errors?

• Algorithm testing

• Syntax testing

• Different forms of testing without specifying

• Logic testing

Answer explanation

Different forms of testing without specifying can be used to locate and debug programming errors as it encompasses various testing methods such as unit testing, integration testing, and system testing.

What does planning a birthday party for Aiden using logic involve?

• Deciding on a theme, creating a guest list and sending invitations, and/or organizing activities and food

• Following a party planning checklist

• Resolving scheduling conflicts

• Writing a schedule of events

Answer explanation

Solving a problem using logic involves planning a strategy, designing and testing a hypothesis, and/or creating a set of step-by-step instructions to perform a task.

When Liam is trying to improve his garden's layout, the process involves all of the following EXCEPT:

• A. Planning the layout and choosing plants

• B. Testing soil quality and sunlight exposure

• C. Writing down a detailed plan of action

• D. Choosing a specific brand of gardening tools

Answer explanation

Solving a problem using logic does not require using a specific programming language, as logic can be applied universally regardless of the language used.

Imagine Jackson is working on a project that requires fast execution speed and William prefers a project that allows quick testing and iteration. James mentioned that Jackson might be using a compiled programming language, while William is likely using an interpreted programming language. What is the main difference between the programming languages Jackson and William are using?

• There is no difference; both are using the same type of programming language.

• Jackson's language is executed directly by the computer, while William's language is not.

• Jackson's language is written by hand, while William's language is written on a computer.

• Jackson's language is slower than William's language.

Answer explanation

A compiled language is directly executed by the computer, while an interpreted language is not. Compiled languages are translated into machine code before execution, while interpreted languages are translated line by line during execution.

Imagine Anika is writing a cookbook. In the context of programming, what would a recipe in her cookbook represent?

• A type of kitchen appliance.

• A dish that cannot be cooked by anyone.

• A set of instructions to be followed in preparing a dish.

• A language used for writing cookbooks.

Answer explanation

An algorithm in programming refers to a set of rules followed in calculations or problem-solving operations, guiding the computer on how to perform a task.

Imagine Henry is working on a program that calculates the total cost of groceries. If he accidentally multiplies the price of apples by 2 instead of adding the tax, what kind of error has he made?

• An error that occurs when the program runs out of memory.

• A mistake in the program that leads to incorrect results.

• An error that happens when the internet connection is lost.

• A syntax error that prevents the program from running.

Answer explanation

A 'logic error' in programming is a mistake in the program that leads to incorrect results, not related to syntax or memory issues.

How did Ava apply problem-solving skills in her project for creating a new app?

• By using algorithms and examining their applications in everyday tasks

• Through advanced calculus techniques

• By conducting a historical analysis of computer development

• Studying internet protocols

Answer explanation

The problem-solving skills introduced in this lesson for writing computer programs involve using algorithms and examining their daily applications.
