Hello everyone,
I am writing a program that use structures and I have a couple questions. First if I am reading the data from a text file in to an array of structure how is the data laid out in the text file (i.e. name, dob, height, etc.) And then secondly how do I read in the data. In function2 and 3 is where I am trying to read the data into the array from the text files.
Here is my code so far
ThanksCode:#include <stdio.h> #include <string.h> #define intiSize 0 typedef struct { char ( name [] ); int dob; int height; char ( father [] ); char ( mother [] ); } horse; typedef struct { char ( raceDay [] ); int trackNum; char ( raceTime [] ); char ( horses [] ); } race; /* Function Prototype */ int menu(); void loadHorse( horse ); void loadRace ( race ); /* Function main begins program execution */ int main() { horse horses [ intiSize ]; horse *horsePtr = &horses [ 0 ]; race races [ intiSize ]; race *racePtr = &races [ 0 ]; loadHorse( *horsePtr ); loadRace ( *racePtr ); menu(); /* Indicates successful termination */ return 0; } /* End Main */ /* Function1 menu definition */ int menu() { int option; while( option != 7 ){ printf( "\n- Horse Farm Management System Main Menu -\n\n" ); printf( " 1.) Add a Horse\n" ); printf( " 2.) Add a Race\n" ); printf( " 3.) View Horse Information\n" ); printf( " 4.) Sort Horse Information\n" ); printf( " 5.) View Race Information by Track\n" ); printf( " 6.) View Race Information by Horse\n" ); printf( " 7.) Exit\n\n" ); printf( " Choose an option: " ); scanf( "%d", &option ); if ( option == 1 ) printf( "\nCall Function Add_New_Horse\n" ); else if ( option == 2 ) printf( "\nCall Function Add_New_Race\n" ); else if ( option == 3 ) printf( "\nCall Function View_Horses\n" ); else if ( option == 4 ) printf( "\nCall Function Sort_Horses\n" ); else if ( option == 5 ) printf( "\nCall Function View_Race_Information_By_Track\n" ); else if ( option == 6 ) printf( "\nCall Function View_Race_Information_By_Horse\n" ); } return 0; } /*End function menu */ /* Function2 loadHorse definition */ void loadHorse( horse horses ) { char horses []; /* Data records */ FILE *cfPtr; /* cfPtr = horses.txt pointer */ /* Fopen opens file; creates file if cannot be opened */ if ( ( cfPtr = fopen( "horses.txt", "r" ) ) == NULL ) { printf( "\nFile does not exist - Creating 'horses.txt'\n" ); if ( ( cfPtr = fopen( "horses.txt", "w" ) ) == NULL ) { } /* End if */ } /* End if */ /* Read records from file */ else { /* While not end of file */ while( !feof( cfPtr ) ) { fscanf( cfPtr, "%s", horses ); } /* End while */ fclose( cfPtr ); /* fclose closes the file */ } /* End else */ } /*End function menu */ /* Function3 loadRace definition */ void loadRace( race races ) { char races []; /* Data records */ FILE *cfPtr; /* cfPtr = races.txt pointer */ /* Fopen opens file; creates file if cannot be opened */ if ( ( cfPtr = fopen( "races.txt", "r" ) ) == NULL ) { printf( "\nFile does not exist - Creating 'races.txt'\n\n" ); if ( ( cfPtr = fopen( "races.txt", "w" ) ) == NULL ) { } /* End if */ } /* End if */ /* Read records from file */ else { /* While not end of file */ while( !feof( cfPtr ) ) { fscanf( cfPtr, "%s", races ); } /* End while */ fclose( cfPtr ); /* fclose closes the file */ } /* End else */ } /*End function menu */
