)

func main() {
    tc := turkish_cities.Load()

    firstCity := tc.GetCities()[0]
    firstTown := firstCity.GetTowns()[0]
    firstDistrict := firstTown.GetDistricts()[0]
    firstQuarter := firstDistrict.GetQuarters()[0]

    fmt.Println("total cities count: ", len(tc.GetCities()))
    // total cities count:  81

    fmt.Println("city id: ", firstCity.ID)
    // city id:  69

    fmt.Println("city name: ", firstCity.Name)
    // city name:  Bayburt

    fmt.Println("city latitude/longitude: ", firstCity.Location.Latitude, firstCity.Location.Longitude)
    // city latitude/longitude:  0x140000a7828 0x140000a7830

    fmt.Println("towns of city count: ", len(firstCity.GetTowns()))
    // towns of city count:  3

    fmt.Println("town id: ", firstTown.ID)
    // town id:  884

    fmt.Println("town name: ", firstTown.Name)
    // town name:  Aydıntepe

    fmt.Println("town latitude/longitude: ", firstTown.Location.Latitude, firstTown.Location.Longitude)
    // town latitude/longitude:  0x140000a6928 0x140000a6930

    fmt.Println("districts of town count: ", len(firstTown.GetDistricts()))
    // districts of town count:  2

    fmt.Println("district id: ", firstDistrict.ID)
    // district id:  4166

    fmt.Println("district name: ", firstDistrict.Name)
    // district name:  Aydıntepe

    fmt.Println("district latitude/longitude: ", firstDistrict.Location.Latitude, firstDistrict.Location.Longitude)
    // district latitude/longitude:  <nil> <nil>

    fmt.Println("quarters of district count: ", len(firstDistrict.GetQuarters()))
    // quarters of district count:  5

    fmt.Println("quarter id: ", firstQuarter.ID)
    // quarter id:  47917

    fmt.Println("quarter name: ", firstQuarter.Name)
