A set of steps or rules to follow to solve a particular problem.

• algorithm

• Decomposition

• Function

• control structures

The process of breaking down your code into smaller parts (more functions)

• Decomposition

• Indentation

• lowerCamelCase

• Start Function

Teaching the computer a new command. Used to explain what a program should do when receiving that command.

• Defining a Function

• Calling a Function

• Start Function

• Readability

Used to teach Karel a new word or command. Using these allows programs to be broken down into smaller pieces and makes it easier to understand.

• Functions

• Control Structures

• algorithms

• Indentation

Choose TWO: Ways (using syntax) that you can write comments?

• multi-line

  """/*

  *

  */"""

• single line

  //

• multi-line

  **

• single line

Which of the following commands is a valid Karel command?

• move

• move( )

• move( );

• move;

Which of the following is the correct way to define a turnRight function in Karel?

• function turnRight() {

  turnLeft();

  turnLeft();

  turnLeft();

  }

• function turnRight() {

  turnRight();

  turnRight();

  turnRight();

  }

• function turnRight {

  turnLeft();

  turnLeft();

  turnLeft();

  }

• turnRight function() {

  turnLeft();

  turnLeft();

  turnLeft();

  }

Say you want to write a program to have Karel put down 300 tennis balls. Which control structure would you use?

• If statement

• While loop

• For loop

• Nested while loop

What is top down design?

• Top down design is a way to use loops and if statements to decompose the problem

• Top down design is a way of designing your programs starting with the individual commands first

• Top down design is a way of designing your program by starting with the biggest problem and breaking it down into smaller and smaller pieces that are easier to solve.

• Top down design is a way that you can create designs on a computer to put on a web page

How can we improve the following program?

function start() {

move();

move();

move();

move();

move();

move();

move();

move();

move();

}

• Break down this program into more functions

• Use a for loop to repeat the move command

• Use a while loop to repeat the move command

• Fix the indentation of this program
