What is decomposition?

What are algorithms used for?

To plan out the solution to a problem

A set of basic steps that the human can use to plan the program

The process of removing unnecessary details from a problem.

Decomposition is a term used to define...

The process of breaking down problems into smaller problems.

A graphical representation of algorithms.

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

The action of doing something over and over again.

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.

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

What is the correct definition of an algorithm?

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

To enable Karel to execute commands conditionally

How does an else statement differ from an if statement?

It executes when the 'if condition' is false.

Which code will put Karel in the position shown in second world? Options: putBall(); putBall(); move(); move();, move(); putBall(); move(); putBall();, putBall(); move(); putBall(); move();, move(); putBall(); putBall(); move();

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

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

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();

What is the right way to write the function: makePancakes (Clue: this pancake will be made by putting 3 balls) Options: function makePancakes(){ putBall(); putBall(); putBall(); } , function makePancakes() putBall(); putBall(); putBall(); , function makePancakes: { putBall(); putBall(); putBall(); } , function makePancakes(){ putBall(); }

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

What is the main (or start) function?
