Thread: Problem with file i/o

Hi,

I am trying to make a program that reads a txt file and sets the information into a linked list. It is hard for me to explain it, so i will give an example:

The txt file:


Master Rune of Snorri Spangelhelm-------------------------------75 pts

Any blows struck by a weapon engraved with this
rune will always hit. No roll ot his necessary.

Master Rune of Skalf Blackhammer--------------------------------75 pts

Any weapon Bearing this rune will automatically
wound if it hits. No roll to wound required.
Use characters strength for hte save modifier.

Mater Rune of Alaric the Mad--------------------------------------50 pts

This rune cancels an opponents armour saving throw.
When wounded by this weapon, the target is not
allowed an armour saving throw of any kind.

End of txt file

I cant get it to read the name of the rune, point cost of the rune, and the discription. I am trying to either get it into either an array or a linked list. can you help... any ideas would helo

post the part of the code where you are having trouble.
I think using fgets and sscanf should be able to get most of the data into the appropriate places. using strtok and having a special character to denote separate parts of teh text may help.

ok... well the thing is i dont know what i am doing wrong. i am able to read the file ok but, when i get to the second fgets the program messes up. what am i doing wrong?
everything with the // are posibilities but what is the right way.

#include <stdio.h>

char subsection [30];
char discription [500];
char discriptiontemp [80];
int points=0;
int num_of_lines=0;
int i=0;


int main()
{
FILE *inputfile;


inputfile = fopen("Rune2.txt","r");

if (inputfile == NULL)
{
printf("error opening file");
}
else
{

printf("File opened successfully. Loading data...\n");
//fscanf(inputfile, "%s", subsection);

fgets(subsection, 100, inputfile);
fscanf(inputfile, "%d", &points);
fscanf(inputfile, "%d", &num_of_lines);
//fgets(&points, 10, inputfile);
//fgets(&num_of_lines, 10, inputfile);
//inputfile++;
while(i!=num_of_lines)
{

//fscanf(inputfile, " %s ", discription);
//fgets(points, 10, inputfile);
//fgets(num_of_lines, 10, inputfile);
fgets(discriptiontemp, 100, inputfile);
strcat(discription, discriptiontemp);
i++;
//inputfile++;
}

printf("%s \n%d pts \n%s", subsection, points, discription);



}

}

Why are you mixing fscanf with fgets just use fgets and sscanf

ohhhh purty colors quzah

So... if i am getting this correct. i need to store the input of the fgets() into an array and then go through the array and break it up into seperate components?
