Infinite loop when using fscanf
- by user1409641
I wrote this simple program in C, because I'm studying FILES right now at University. I take a txt file with a list of the results of the last race so my program will show the data formatted as I want. Here's my code:
/* Esercizio file Motogp */
#include <stdio.h>
#define SIZE 20
int main ()
{
int pos, punt, num;
float kmh;
char nome[SIZE+1], cognome[SIZE+1], moto[SIZE+1];
char naz[SIZE+1], nome_file[SIZE+1];
FILE *fp;
printf ("Inserisci il nome del file da aprire: ");
gets (nome_file);
fp = fopen (nome_file, "r");
if (fopen == NULL)
printf ("Errore nell' apertura del file %s\n", nome_file);
else {
while (fscanf (fp, "%d %d %d %s %s %s %s %.2f",
&pos, &punt, &num, nome, cognome, naz, moto, &kmh) != EOF ) {
printf ("Posizione di arrivo: %d\n", pos);
printf ("Punteggio: %d\n", punt);
printf ("Numero pilota: %d\n", num);
printf ("Nome pilota: %s\n", nome);
printf ("Cognome pilota: %s\n", cognome);
printf ("Nazione: %s\n", naz);
printf ("Moto: %s\n", moto);
printf ("Media Kmh: %d\n\n", kmh);
}
}
fclose(fp);
return 0;
}
and there's my txt file:
1 25 99 Jorge LORENZO SPA Yamaha 164.4
2 20 26 Dani PEDROSA SPA Honda 164.1
3 16 4 Andrea DOVIZIOSO ITA Yamaha 163.8
4 13 1 Casey STONER AUS Honda 163.8
5 11 35 Cal CRUTCHLOW GBR Yamaha 163.6
6 10 19 Alvaro BAUTISTA SPA Honda 163.5
7 9 46 Valentino ROSSI ITA Ducati 163.3
8 8 6 Stefan BRADL GER Honda 162.9
9 7 69 Nicky HAYDEN USA Ducati 162.5
10 6 11 Ben SPIES USA Yamaha 162.3
11 5 8 Hector BARBERA SPA Ducati 162.1
12 4 17 Karel ABRAHAM CZE Ducati 160.9
13 3 41 Aleix ESPARGARO SPA ART 160.2
14 2 51 Michele PIRRO ITA FTR 160.1
15 1 14 Randy DE PUNIET FRA ART 160.0
16 0 77 James ELLISON GBR ART 159.9
17 0 54 Mattia PASINI ITA ART 159.4
18 0 68 Yonny HERNANDEZ COL BQR 159.4
19 0 9 Danilo PETRUCCI ITA Ioda 158.2
20 0 22 Ivan SILVA SPA BQR 158.2
When I run my program, it return me an infinite loop of the first one. Why?
Is there another function to read those data?
