Thread: Reading from a .txt file into struct array

Hello,

I'm trying to read lines from a .txt file and store them in a struct array. This is my code so far:

Code:

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

#define MAX_SIZE 256


typedefstruct{
    char dayPlayed[4];
    int datePlayed;
    double timePlayed;
    char teamPlayed;
    int score;
    int specs;
} matches[MAX_ARRAY_SIZE];

matches matches_array;

int main(){

    FILE*matchFP;
    matchFP = fopen("matches.txt","r");

    int i =0;
    while(fgets(matches_array,60, matchFP)){
        
        printf("%s", matches_array);
        fscanf(matchFP,"%s, %d, %lf, %s, %d, %d", 
                                    &matches_array[i].day[i], 
                                    &matches_array[i].day,
                                    &matches_array[i].time,
                                    &matches_array[i].teams,
                                    &matches_array[i].score,
                                    &matches_array[i].specs);
        i++;
    }

    printf("\n\n%d", matches_array[2]);

    fclose(matchFP);
    return0;}

And this is my text file:

Fri 2/12 6.00 AUS - USA 1-1 29534
Fri 4/09 8.15 SWE - UK 3-1 35723
Sat 11/05 7.00 ES - POR 1-2 48392

How can I accomplish this? I'm new to programming and would love help on this.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
#define MAX_SIZE 256
 
typedef struct {
    char weekday[4];
    int  month, day;
    int  hour, minutes;
    char away_team[4], home_team[4];
    int  away_score, home_score;
    int  specs;
} Match;
 
// Example line: Fri 2/12 6.00 AUS - USA 1-1 29534
int read_matches(const char *filename, Match *matches) {
    FILE *fin = fopen("matches.txt", "r");
 
    int i = 0;
    while (fscanf(fin, "%s %d/%d %d.%d %s - %s %d-%d %d", 
             matches[i].weekday,
            &matches[i].month,
            &matches[i].day,
            &matches[i].hour,
            &matches[i].minutes,
             matches[i].away_team,
             matches[i].home_team,
            &matches[i].away_score,
            &matches[i].home_score,
            &matches[i].specs) == 10)
        ++i;
 
    fclose(fin);
    return i;
}
 
void print_matches(Match *matches, int size) {
    for (int i = 0; i < size; ++i) {
        Match *m = &matches[i];
        printf("%s %2d/%2d %2d:%02d  %-3s - %-3s  %2d - %2d %6d\n",
            m->weekday, m->month, m->day,
            m->hour, m->minutes,
            m->away_team, m->home_team,
            m->away_score, m->home_score,
            m->specs);
    }
}
 
int main() {
    Match matches[MAX_SIZE];
    int size = read_matches("matches.txt", matches);
    print_matches(matches, size);
    return 0;
}

You didn't have to "quote" my entire post (or any of it) to simply ask a question.
It probably couldn't open the file. I had a mistake in that I opened "matches.txt" instead of filename in read_matches.
Try this:

Code:

int read_matches(const char *filename, Match *matches) {
    FILE *fin = fopen(filename, "r");
    if (!fin) {
        printf("Can't open file: %s\n", filename);
        return 0;
    }
    int i = 0;
    while (fscanf(fin, "%s %d/%d %d.%d %s - %s %d-%d %d", 
             matches[i].weekday,
            &matches[i].month,
            &matches[i].day,
            &matches[i].hour,
            &matches[i].minutes,
             matches[i].away_team,
             matches[i].home_team,
            &matches[i].away_score,
            &matches[i].home_score,
            &matches[i].specs) == 10)
        ++i;


    fclose(fin);
    return i;
}

Well it runs for me just fine, so it's probably just not opening your file. Alternatively, maybe your file doesn't have the exact structure you've presented.
