how to use fgets

[georges the man]

if i have the following data in a text file;

BHp,"12 feb 2006",32.42,2424.35,3535.535
BHP,"13 feb 2006",434.35,3535.5454,353
and so on
using fgets how can i get the program to read the column of BHP, date
each by itself

It is not possible to get the fields in a line using fgets(). Because no field is of fixed length.

I believe what you are asking for is:

you have to read from that text file using delimeter "," to parse (separate the data going into an array, and then search that array for whatever values you need...

You read in a line at a time with fgets() and then you can use strtok() to extract each field in which you are interested.
[php]
while (!feof(i_file)){
while (NULL != fgets(string, BUFSIZ, i_file)){
field_counter = 1;
field = strtok(string, field_delimiters);
while (NULL != field){
switch (field_counter){
case 1:
/* do something with 1st field */
fprintf(o_file, "%s", field);
break;
case 2:
/* do something with 2nd field */
fprintf(o_file, ", %s\n", field);
break;
/* and so on ...
case n:
break;
*/
}
field = strtok(NULL, field_delimiters);
field_counter++;
}
}
if (ferror(i_file)){
perror("Error reading input file");
exit(1);
break;
}
}
