Thread: fgets help

Hi

Can someone point me in the correct direction here

I want to use fgets to read in a stream of data from a text file

I call fgets once and it reads the first line and stores it in my string.
If i call fgets again it does read the next line but it writes over the information in the array stored from the first call of fgets

How can i get it to start storing data in my array where it left off?

Thanks so much

Code:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>



int main( int argc, char *argv[] )
{
  FILE *fptr;

  int count_line=0;
  char temp_array[100];
  char *temp_string;
  temp_string=&temp_array[0];
  int x;


//*****************************************************************************************************************//
for(x=0;x<100;x++){

temp_array[x]='\0';


}

//*****************************************************************************************************************//


  if (argc != 2) {
    fprintf (stderr, "Error: The program is run with 1 input argument");
    exit(-1);
  }

  // Open file and check it is open
  fptr = fopen(argv[1], "r");
  if (fptr == NULL) {
    fprintf (stderr, "Error: Could not open file");
    exit(-1);
  }

//*****************************************************************************************************************//

//load the array up with first line of characters
//This is also going to handle the line count

while(!feof(fptr)){

fgets(temp_string,100,fptr);

count_line++;
}

//*****************************************************************************************************************//



for(x=0;x<10;x++){

printf("This is what is stored in array location %d  ""%c""\n\n",x,temp_array[x]);


}

fprintf(stderr,"This is the count %d\n\n\n\n",count_line-1);//Gedit in linux is adding an addtional line character. The minus one accounts for that.
//different systems may behave differently.





  fclose (fptr);

}

Nevermind, switched to fread and now does what i need

Thanks if i knew how to delete the post i would

Quzah.

fread did exactly as i wanted i wanted the whole file in an array thats it.

but if i use fgets when it goes to read line two it over writes line one see what i mean.

so if i use fread it does it all at once the whole thing.

So it just fills the array with all the data

Do you know of a way to make fgets start stroring in the same array where it left from the previous call?
