input: Write a python function to create a Car class with methods to set and get the make, model, and year, and to get and increment the odometer reading.
  assert car.getMakeAndModel() == "Toyota Corolla"
  assert car.getYear() == 2020
  assert car.getOdometerReading() == 0
  car.incrementOdometer(150)
  assert car.getOdometerReading() == 150
