everybody.
I got logic problem with car odometer, i don't understand how to devide a car age in km by year.
For example i got car with 2015 year and 250 000 km in odometer.
it's ok, if i just minus current year with registration year i got car age then i just deviding a car age in odometer or odo in age depending on numbers. then i got a car km route by year. but what if i want get age of car with 1920 year and 1 km of full route. or car with last year.
it does not show me a current data, in example below
func getOdoByYear(registration: Int, currentYear: Int, currentODO: Int) -> Int {
if currentODO == 0 || currentYear == registration {
return currentODO
}
var carAge = currentYear - registration
if carAge >= currentODO {
return carAge / currentODO
} else {
return currentODO / carAge
}
}
if car registered year before i got a one year of age of car, and if a car route is only 1 km it also cant be calculated from 1920 for example.
In order to calculate the average of kilometers traveled in a year by a car, you should just divide the km traveled by the age of the car.
Example, given:
the average of km traveled in a year is calculated by:
7 km / (2024 - 1920) ~ 67.31 m/year
Code example:
func getOdoByYear(registration: Int, currentYear: Int, currentODO: Int) -> Double {
// TODO: check parameters, i.e. currentYear > registration, currentODO >= 0
var carAge = currentYear - registration
var average:Double = Double(currentODO) / Double(carAge)
return average
}
you also should handle the case registration == currentYear, otherwise you get a division by zero. This is up to you: you can just return the currentODO (even the first year is not completed yet) or throw an error because it might not make sense at all.
