What is the purpose of an if statement in programming?

An if statement in programming is used to perform different actions based on whether a certain condition is true or false.

An if statement in programming is used to perform mathematical calculations.

An if statement in programming is used to declare variables.

An if statement in programming is used to perform the same actions regardless of whether a certain condition is true or false.

What is the difference between a while loop and a for loop in programming?

A while loop is used when the number of iterations is known, while a for loop is used when the number of iterations is unknown.

A while loop and a for loop are the same thing.

A while loop is used when the number of iterations is unknown, while a for loop is used when the number of iterations is known.

A while loop can only be used in object-oriented programming, while a for loop can be used in any programming language.

Repeating actions that have a predetermined beginning, end, and increment (step interval)

a named group of programming instructions; reusable abstractions that reduce the complexity of writing and maintaining programs

A base-16 number system that uses sixteen distinct symbols 0-9 and A-F to represent numbers from 0 to 15.

A precise sequence of instructions for processes that can be executed by a computer

Application Program Interface: a collection of commands made available to a programmer

a named group of programming instructions; reusable abstractions that reduce the complexity of writing and maintaining programs

Repeating actions that have a predetermined beginning, end, and increment (step interval)

To repeat in order to achieve, or get closer to, a desired goal.

parts of a problem's solution (the overall goal); helps you focus on figuring out which block(s) you need rather than trying to solve the whole problem at once.

a description of the behavior of a command, function, library, API, etc.

The action of doing something over and over again.

the optimal time a program takes to run on a computer, the optimal time or number of people required to create, the optimal number of resources required to run, etc

A programming language with many commands and features designed to make common tasks easier to program; encapsulated as combinations of low level commands.

a named group of programming instructions; reusable abstractions that reduce the complexity of writing and maintaining programs

a collection of commands / functions, typically with a shared purpose

aka "stepwise design", a problem solving approach in which you break down a system to gain insight into the sub-systems that make it up.

Application Program Interface: a collection of commands made available to a programmer

The action of doing something over and over again.

a simplified representation of something more complex; allows you to hide details to help you manage complexity, focus on relevant concepts, and reason about problems at a higher level.

A generic term for a type of programming statement (usually an if-statement) that uses a Boolean condition to determine, or select, whether or not to run a certain block of statements.

A language that your computer understands. Written in a set of instructions.

Create a secret language that you understand and other people need to decode.

What is the correct definition of an algorithm?

An algorithm is step by step instructions to solve a problem.

An algorithm is a process of baking bread.

An algorithm is a software used to compute numbers.

An algorithm is the process of breaking problems.

What is the role of an if statement in Karel's programming logic?

To enable Karel to execute commands conditionally

To initialize Karel's starting position

How does an else statement differ from an if statement?

It executes when the 'if condition' is false

It always executes, regardless of conditions

It executes when the 'if condition' is true

It can only be used with numbers, not booleans

Which code will put Karel in the position shown in second world?

move(); putBall(); putBall(); move();

putBall(); putBall(); move(); move();

move(); putBall(); move(); putBall();

putBall(); move(); putBall(); move();

Precondition: Karel is in location (1,1) facing east. Which code below will put Karel in the position shown in picture?

move(); move(); turnLeft(); move();

move(); Move(); turnLeft(); move();

move; move(); turnLeft; move();

move(); move(); TurnLeft(); Move();

Karel needs to move forward, then turn left, then move forward, then put down a ball.

move(); turnLeft(); move(); putBall();

move(); turnLeft(); move(); takeBall();

move(); turnLeft(); move(); move();

move(); turnLeft() move(); putBall()

Karel needs to take the ball that is already present on her initial space then move forward four spaces and place the ball. Then turn Left

takeBall(); move(); move(); move(); move(); putBall(); turnLeft();

takeBall(); move 2 times (); move 2 times (); putBall(); turnLeft

takeBall(); move(); move(); putBall(); TurnLeft{};

takeBall(); move(4); putBall(); turnLeft():

What is the right way to write the function: makePancakes (Clue: this pancake will be made by putting 3 balls)

function makePancakes(){ putBall(); putBall(); putBall(); }

function makePancakes() putBall(); putBall(); putBall();

function makePancakes: { putBall(); putBall(); putBall(); }

function makePancakes(){ putBall(); }

What is the main (or start) function?

It is the main body of a program, where all other functions are called up.

It is the start of a racing program.

It is another function like all others that can be written with any definition you want.
