Question on STRTOK...

atilladehun

Hi,

I'm havin a problem with a part of my c program. I'm using strtok and want to take this info from a text file:

a 0.1 0.2 0.3
b 1.1 1.2 1.3
c 3.1 3.2 3.3

it's taking it all in no problem and the numbers are stayin fine but the letters keep being over written so that when i print it out all i see is

c 0.1 0.2 0.3
c 1.1 1.2 1.3
c 3.1 3.2 3.3


This is my code:

while(fgets(line, 1024, mixfile))

{

printf("%s", line);



if (line[0]!='#')

{

name[filecount] = strtok(line, " \t\r\n"); // Why overwriting the names?

start[filecount]= atof(strtok(NULL, " \t\r\n"));

gain[filecount] = atof(strtok(NULL, " \t\r\n"));

pan[filecount] = atof(strtok(NULL, " \t\r\n"));

printf("\n%s\n", name[filecount]);

filecount++;

}

}




for (i=0; i<filecount; i++)

{

printf("\n%d: %s %.1f %.1f %.1f\n", i, name, start, gain, pan);

}

I don't know whats wrong. Any clues?

You're populating name[] with pointers to 'line'. Line keeps changing. You should be doing something like strcpy(name, strtok(line....). Obviously, you must allocate memory appropriately.
