Hi plis help me to solve my code problem

#include <SoftwareSerial.h>
#include <TinyGPS++.h>

TinyGPSPlus gps;
SoftwareSerial ss(3, 4);

void setup() {
Serial.begin(9600);
ss.begin(9600);

}

void loop() {
while (ss.available() > 0)
gps.encode(ss.read());
if (gps.altitude.isUpdated()){
Serial.print("LAT="); Serial.println(gps.location.lat(), 6);
Serial.print("LONG="); Serial.println(gps.location.lng(), 6);
Serial.print("ALT="); Serial.println(gps.altitude.meters(),6);
Serial.print("\n");

const double DEST_LAT = 48.85826;
const double DEST_LON = 2.294516;
double distanceKm =
TinyGPSPlus.distanceBetween(
double gps.location.lat(),
double gps.location.lng(),
DEST_LAT,
DEST_LON) / 1000.0;

double courseTo =
TinyGPSPlus.courseTo(
gps.location.lat(),
gps.location.lng(),
DEST_LAT,
DEST_LON);

Serial.print("Distance (km) to Destination: ");
Serial.println(distanceKm);
Serial.print("Course to Destination: ");
Serial.println(courseTo);
Serial.print("Human directions: ");
Serial.println(TinyGPSPlus.cardinal(courseTo));
}
}

the message
expected primary-expression before '.' token

Shouldn't that be

gps.distanceBetween{

etc.

Doesn't look like you changed anything. Show your new code - in code tags

I still can't see what you changed to match my suggestion.

Every place you have TinyGPSPlus. change it to gps.

Do not change TinyGPSPlus gps;

And, before re-posting, hit ctrl-t in the Arduino IDE so the indenting doesn't look like crap.

oke thanks for help. i changed my code and thats work
