Question

Karel is so excited for New Years Day! Karel wants to build a firework. Write a program that has Karel create a firework of tennis balls.

The key in this program is to break the problem down into several smaller problems and use functions to solve each smaller problem.

Answer 1

// Karel will create a firework of tennis balls

// Define a function to move Karel to the starting position
function moveToStartPosition() {
move();
turnLeft();
move();
turnRight();
}

// Define a function to place a tennis ball
function placeTennisBall() {
putBeeper();
move();
}

// Define a function to turn Karel to the right
function turnRight() {
turnLeft();
turnLeft();
turnLeft();
}

// Define a function to create a firework of tennis balls
function createFirework() {
moveToStartPosition();
for (var i = 0; i < 4; i++) {
placeTennisBall();
turnRight();
}
}

// Call the createFirework function to create the firework
createFirework();
