Question

karel got spun around and is facing the wrong direction. karel could be facing south or west, and you need to get karel back to facing east. you must use an if/else statement here.

Answer 1

To get Karel facing east when he is currently facing south or west, use an if/else statement to perform a series of turns using commands like turnLeft() or turnRight() depending on his current direction.

Step-by-step explanation:

If Karel is facing south or west and you need him to face east using an if/else statement, you will need to have Karel turn the appropriate number of times until he is facing east. Assuming you are using a programming language where Karel can execute commands like turnLeft() or turnRight(), here's an example of what the code might look like:

if (Karel is facing south) {
turnLeft(); // Karel will now be facing east
} else if (Karel is facing west) {
turnRight();
turnRight(); // Karel will now be facing east
}
This code uses an if/else statement to check Karel's direction and performs the necessary turns to redirect him towards the east. It's important to note that the exact commands can vary depending on the programming environment Karel is in.

Answer 2

To get Karel to face east, you can use an if/else statement to determine whether to make Karel turn left from south or turn right twice from west.

Step-by-step explanation:

To correct Karel's orientation and ensure he is facing east, we can use an if/else statement to check his current direction. Since Karel can only be facing south or west, the logic would dictate that if Karel is facing south, he needs to turn left to face east. If Karel is facing west, he would need to turn right twice to be facing east. Here's an example of how this could be coded:

if (karel.isFacingSouth()) {
karel.turnLeft(); // Karel turns left to face east
} else {
karel.turnRight();
karel.turnRight(); // Karel turns right twice to face east
}

This approach ensures that Karel ends up facing east regardless of whether he initially faces south or west.
