Perhaps you failed to notice that this is the English language portion of the forum.
When I compile your code, I get:
sketch_apr27a.ino: In function 'void setup()':
sketch_apr27a:13: error: no matching function for call to 'TinyGPS::get_position(long int*)'
C:\Users\pjs9486\Documents\Arduino\libraries\TinyGPS/TinyGPS.h:58: note: candidates are: void TinyGPS::get_position(long int*, long int*, long unsigned int*)
sketch_apr27a:14: error: no matching function for call to 'TinyGPS::get_position(long int*)'
C:\Users\pjs9486\Documents\Arduino\libraries\TinyGPS/TinyGPS.h:58: note: candidates are: void TinyGPS::get_position(long int*, long int*, long unsigned int*)
So, why do you think that get_position() takes one argument?
