Print Struct to file

I want to print the struct to a .txt file. When I compile my code my final printf returns the values I input just fine but my fprintf saves some strange symbols into the text file. Can anyone please help me debug this?

Code:

---

#include <stdio.h>
#include <stdlib.h>

   

int main ()

{
 struct
 {
  char user_airportdestination[5];
  char user_airportorigin[5];
  char user_maker[7];
  char user_model[4];
  char user_flightnumber[8];
  char user_tailnumber[8];
  float user_altitude;
  float user_heading;
  float user_trackangle;
  float user_gspeed;
  float user_airtemp;
  float user_latitude;
  float user_longitude;
 } data;
 
  printf("Aircraft data acquisition\nThis program acquires user data and saves it into a file\nPress enter to continue");
  getchar();
  system("cls");
  printf ("Airport Destination:\n");
  scanf ("%s",&data.user_airportdestination);

  printf ("Airport Origin:\n");
  scanf ("%s",&data.user_airportorigin);
 
  printf ("Aircraft Maker:\n");
  scanf ("%s",&data.user_maker);
 
  printf ("Aircraft Model:\n");
  scanf ("%s",&data.user_model);
 
  printf ("Flight Number:\n");
  scanf ("%s",&data.user_flightnumber);
 
  printf ("Aircraft's Tail Number:\n");
  scanf ("%s",&EFBdata.user_tailnumber);
 
  printf ("Altitude:\n");
  scanf ("%f",&data.user_altitude);
     
  printf ("Heading:\n");
  scanf ("%f",&EFBdata.user_heading);

  printf ("Track Angle:\n");
  scanf ("%f",&data.user_trackangle);
 
  printf ("Groundspeed:\n");
  scanf ("%f",&EFBdata.user_gspeed);
 
  printf ("Static Air Temperature (degrees Celsius):\n");
  scanf ("%f",&data.user_latitude);
 
  printf ("Latitude:\n");
  scanf ("%f",&EFBdata.user_latitude);
 
  printf ("Longitude:\n");
  scanf ("%f",&data.user_longitude);
 

 printf ("Data acquired %s\n%f", data.user_airportdestination, data.user_latitude);
 getchar();

  FILE *file;
  file = fopen("user_input.txt","w");
  fprintf(file,"%s %f", data.user_airportdestination, data.user_latitude); //writes//
  printf ("Data saved in user_input.txt");
  getchar(); // pause and wait for key //
 
 

  return 0;
}

Thanks!

Code:

---

printf ("Data acquired %s\n%f", data.user_airportdestination, data.user_latitude);
 getchar();

  FILE *file;
  file = fopen("user_input.txt","w");
  fprintf(file,"%s %f", data.user_airportdestination, data.user_latitude); //writes//

If that red part prints okay the file output should also be okay. Are you sure this is exactly the code you are using? Maybe put a /n in and fclose() the file to make sure it is flushed.

My first guess would be that you're typing in longer strings than your short arrays allow for.

Post some examples of user input which display corrupt data.

Thanks Salem and MK27. The fclose() solved the problem. :)
Is there a way I can print out the entire struct at once rather than having to call each variable separately?

Not if you want to read the file as text. If you just want to store the data, you can write straight out -- except you have a pointer in the struct, which there is no point in recording addresses.
