CodeHS - Intro to Programming with Karel the Dog - Vocab Quiz

What is indentation

• { and a close curly bracket is }

• The way your code is written is the style. It covers the aspects of the code that goes beyond whether or not it just works.

• 
  the visual structure of how your code is laid out. It uses tabs to organize code into a hierarchy.

Answer explanation

Indentation refers to the visual structure of how your code is laid out, using tabs or spaces to organize code into a hierarchy. This enhances readability and helps in understanding the code's flow.

What is programming style

• the visual structure of how your code is laid out. It uses tabs to organize code into a hierarchy.

• The way your code is written is the style. It covers the aspects of the code that goes beyond whether or not it just works.

• { and a close curly bracket is }

Answer explanation

The correct choice highlights that programming style refers to how code is written, encompassing readability, organization, and maintainability, rather than just functionality. It emphasizes the importance of code aesthetics.

What is a curly bracket?

• The way your code is written is the style. It covers the aspects of the code that goes beyond whether or not it just works.

• the visual structure of how your code is laid out. It uses tabs to organize code into a hierarchy.

• { and a close curly bracket is }

Answer explanation

A curly bracket is represented by the symbols { and }. It is used in programming to define blocks of code, such as functions or loops, making the correct choice the one that identifies these symbols.

What is a Fencepost Problem

• lets us change the flow of the code.

• Control structure that lets us run either one section of code or another depending on a test.

• breaking your program into smaller parts.

• A problem when using a while loop where you forget one action at the beginning or the end.

Answer explanation

The Fencepost Problem occurs when using a while loop and forgetting to include an action at either the start or the end, leading to off-by-one errors. This makes the correct choice about the problem's nature.

What is Control Structure

• change the flow of the code.

• 
  Control structure that lets us run either one section of code or another depending on a test.

• 
  breaking your program into smaller parts.

Answer explanation

A control structure is a programming construct that changes the flow of the code, allowing for decisions and branching based on conditions. Thus, the correct choice is 'change the flow of the code.'.

What is If Else Statement

• Breaking down (decomposing) your code is splitting it into more functions.

• Control structure that lets us run either one section of code or another depending on a test.

• Lets us repeat code as long as something is true.

Answer explanation

An If Else Statement is a control structure that allows the execution of one block of code if a condition is true, and another block if it is false. This is why the correct choice describes it as running code based on a test.

What is Decomposition

• Breaking down (decomposing) your code is splitting it into more functions.

• A control structure lets us change the flow of the code.

• breaking your program into smaller parts.

Answer explanation

Decomposition refers to breaking your program into smaller parts, which makes it easier to manage and understand. The correct choice highlights this concept, while the other option discusses control structures, which is unrelated.

What is a Loop?

• lets us repeat code a fixed number of times.

• a way to repeat code in your program.

• Lets us repeat code as long as something is true.

Answer explanation

A loop is fundamentally a way to repeat code in your program. The other options describe specific types of loops, but the correct answer captures the general concept of looping.

What is an If Statement?

• Programs that “Read like a story” have good decomposition and make the code easy to follow.

• Control structure that lets us run either one section of code or another depending on a test.

• lets you ask a question to the program and only run code if the answer is true.

Answer explanation

The correct choice explains that an If Statement allows you to ask a question to the program and execute code only if the answer is true, which is the fundamental purpose of this control structure.

What does it mean to Read Like a Story?

• have good decomposition and make the code easy to follow.

• lets you ask a question to the program and only run code if the answer is true.

• lets us change the flow of the code.

Answer explanation

"Read Like a Story" means having good decomposition, which makes the code easier to follow. This approach enhances readability and helps others understand the logic and flow of the program, similar to how a narrative unfolds.
