I have a problem when I try to read the file information for my struct with fscanf()
. It just reads the first line of the string and the loop never ends. How can I solve the problem?
Struct
typedef struct {
int id;
char name[80];
char nameStadium[80];
int numberPlacesStadium;
float funds;
float monthlyExpenses;
int active;
} Team;
And I use this code to read
void showAll(void)
{
FILE* file;
Team team;
file = fopen("file.txt", "rt");
if (file == NULL)
{
printf("!!!Cant open file!!!\n");
return;
}
rewind(file);
printf("\n\n=== TEAMS ======\n");
printf("%s\t%s\n", "ID", "NAME");
while (fscanf(file, "%6d %s %s %6d %f %f %03d\n", &team.id, team.name, team.nameStadium, &team.numberPlacesStadium, &team.funds, &team.monthlyExpenses, &team.active) != EOF)
{
if (team.active != 0)
{
printf("%d\t%s\n", team.id, team.name);
}
}
fclose(file);
}
I can't understand why fscanf()
just gets the first word and not the full string
Does anyone know how to solve this?
I just tested out your code with a sample text file I made following the format you posted. Everything is read in and seems to be fine except that you didn't properly close the file. It should look like this.
fclose(file);
If you want your code to be able to read in strings with spaces, your best bet is to use a delimiter system. The code below reads for their type (assuming the integers won't have spaces in-between them), reads for a sequence of 80 characters that aren't commas (which will be the names), and then proceeds with the other numbers separated by commas.
while (fscanf(file, "%d, %80[^,], %80[^,], %d, %f, %f, %d\n", &team.id,
team.name, team.nameStadium, &team.numberPlacesStadium, &team.funds,
&team.monthlyExpenses, &team.active) != EOF)
{
if (team.active != 0)
{
printf("%d\t%s %s\n", team.id, team.name, team.nameStadium);
}
}
I've tested it to work and it does, but keep in mind this also isn't the most elegant solution.
These are what the rows in my text file looks like:
133222, Bears, Bears Stadium, 444333, 23, 35.3, 52
666222, Eagles, Eagles Stadium, 322222, 13, 56.3, 54
