Using fgets to read strings from file in C
- by Ivan
I am trying to read strings from a file that has each string on a new line but I think it reads a newline character once instead of a string and I don't know why. If I'm going about reading strings the wrong way please correct me.
i=0;
F1 = fopen("alg.txt", "r");
F2 = fopen("tul.txt", "w");
if(!feof(F1)) {
do{ //start scanning file
fgets(inimene[i].Enimi, 20, F1);
fgets(inimene[i].Pnimi, 20, F1);
fgets(inimene[i].Kood, 12, F1);
printf("i=%d\nEnimi=%s\nPnimi=%s\nKaad=%s",i,inimene[i].Enimi,inimene[i].Pnimi,inimene[i].Kood);
i++;}
while(!feof(F1));};
/*finish getting structs*/
The printf is there to let me see what was read into what and here is the result
i=0
Enimi=peter
Pnimi=pupkin
Kood=223456iatb i=1
Enimi=
Pnimi=masha
Kaad=gubkina
i=2
Enimi=234567iasb
Pnimi=sasha
Kood=dudkina
As you can see after the first struct is read there is a blank(a newline?) onct and then everything is shifted. I suppose I could read a dummy string to absorb that extra blank and then nothing would be shifted, but that doesn't help me understand the problem and avoid in the future.
