Story

In this exercise you'll be playing around with a remote controlled car, which you've finally saved enough money for to buy.

Cars start with full (100%) batteries. Each time you drive the car using the remote control, it covers 20 meters and drains one percent of the battery.

The remote controlled car has a fancy LED display that shows two bits of information:

  • The total distance it has driven, displayed as: "Driven <METERS> meters".
  • The remaining battery charge, displayed as: "Battery at <PERCENTAGE>%".

If the battery is at 0%, you can't drive the car anymore and the battery display will show "Battery empty".

Tasks

These are example tasks that fit the remote control car exercise:

  • Buy a brand-new remote controlled car
  • Display the distance driven
  • Display the battery percentage
  • Update the number of meters driven when driving
  • Update the battery percentage when driving
  • Prevent driving when the battery is drained
