C problem

fyp

Im trying to take the following type of data from a file(*.phn) and storing it in 2 int arrays and an array of strings
0 2360 h#
2360 5263 sh
5263 7021 iy
7021 8370 hv
8370 1023 tcl
1023 1260 h#

Im trying to acommplish this using the following code
fpointer = fopen("sa1.phn","r");
while(!feof(fpointer))
{
fscanf(fpointer,"%d %d %s",&start[count],&stop[count],label[count]);
count = count + 1 ;
}
fclose(fpointer);

When i try to run this code windows tells we that the program has done something illegal and an error log has been created.I think it has something to do with the third row of characters being taken in but i dont know what?

Does anybody know what is wrong or have any advice!!

what is label? if its an array of char then your trying to read a string into a char.

I got it to work using the following code (incl declarations) on Linux with gcc 3.3.3.

#include <stdio.h>

int main()
{
    FILE * fpointer;
    int start[10], stop[10];
    char label[10][10];
    int count = 0;
    int items;

    fpointer = fopen("sa1.phn","r");
    /* Maybe have a do/while loop instead so feof() check at end? */
    while(!feof(fpointer))
    {
        items = fscanf(fpointer,"%d %d %s",&start[count],&stop[count],label[count]);
        /* fscanf returns EOF when it hits end of file. */
        if ( items != EOF )
        {
            /* Just to see what was parsed. */
            printf( "%d: %d,%d,%s\n", items, start[count], stop[count], label[count] );
            count++;
        }
    }
    fclose(fpointer);

    return 0;
}

The problem might be, as jessy mentioned, the declaration of 'label'.

Thanks very much for your suggestions Jessy and daymobrew my C is rusty ,and i have been progrmming in matlab for a long while i think it was my declaration of label which was changed and now works.

Unfortunately i have encoutered another problem taking in the data.And i was wondering if anybody knew what was going on
This data is what i want to bring into the program
0 3050 h#
3050 4559 sh
4559 5723 ix
5723 6642 hv
6642 8772 eh
8772 9190 dcl
9190 10337 jh
10337 11517 ih
11517 12500 dcl
12500 12640 d
12640 14714 ah
14714 15870 kcl
15870 16334 k
16334 18088 s

And it comes out like this
0 3050 h#
3050 4559 sh
4559 5723 ix
5723 6642 hv
6642 8772 z9
8772 9190
9190 10337 *«
10337 11517 ih
7103332 12500 dcl
12500 12640
12640 14714 y¥
14714 15870 kcl
15870 16334 %
16334 18088 s

Also while im at it does anybody know how to take in a wave file into a c programme?

daymobrew

What did you declare 'label' to be?

What exactly do you want to do with it? Play it perhaps?
You *could* find out the size of the file, allocate memory and read it all it. But that might not be any use. All depends on what you want to do with it.

jessy

format of wave file
http://ccrma.stanford.edu/CCRMA/Courses/422/projects/WaveFormat/

should be very easy once you know the format.

Concerning the wave file (which is a line of speech) i wish to take it into a program and segment the speech using the sample numbers in the file as indexe to the wave file.
Another problem is i want to store different length vectors of sampled speech data and i was thinking of using an array of pointers to int
Any suggestions

label was declared as follows:
char label[3][50];
fscanf(fpointer,"%d %d %s",&start[count],&stop[count],label[count]);

daymobrew

label was declared as follows:
char label[3][50];

No wonder it failed.
You declared 3 elements of 50 chars. I'm guessing you wanted 50 elements of 3 chars.
That is:

char label[50][3];

but you need to store the trailing NULL char so you need 4 spaces to store 'dhl' (4th space for '\0' (aka NULL char).

So I recommend changing the declaration to

char label[50][4];
