Read blank delimeted textfile

Hello,

I have a problem with reading a textfile. My actual code:

Code:

int main(int argc, char *argv[])
{
  char *pstr[30];
  float *pflo[20];
  FILE *datin;
  int i,j,readint;

      
        datin=fopen("data.dat","r");


                /* Data file holds always exactly 9 values */

                for (j=0; j<=8; j++)
                {

                readint = fscanf(datin, "%s%f", pstr[i], &pflo[i]);

                /* Output */
                printf("%s\t%f\n", pstr[i], &pflo[i]);
                }

        /* Close*/
        fclose(datin);

  return 0;
}

the textfile looks like

Machine1 2.00012
Machine2 2.04523
...
...
and so on until Machine9

I get always an memory access error and don't know why.

You haven't allocated memory to the array pstr. Did you mean to use a two-dimensional array of char as an array of strings (rather than the array of pointers to char that you have)?

[edit]Pretty much the same goes for your array of pointers to float.

[edit]And some other things.

Code:

#include <stdio.h>

int main(void)
{
   FILE *datin = fopen("data.dat","r");
   if ( datin != NULL )
   {
      char  pstr[9][30];
      float pflo[9];
      int   j;
      for ( j = 0; j < 9; ++j )
      {
         if ( fscanf(datin, "%s%f", pstr[j], &pflo[j]) != 2 )
         {
            break; /* OOPS */
         }
         printf("%s\t%f\n", pstr[j], pflo[j]);
      }
      fclose(datin);
   }
   return 0;
}

Strange, normally it should work with the variable initialisation. No, I use string and float numbers seperately. No 2 dimensional array.

Another version of this code works, but only the strings of the first column are written correctly. And this without memory allocation ...

Nope, doesn't work

String output is correct, value output is wrong

data.dat:

Code:

Machine1 2.00012
Machine2 2.04523

my output:

Code:

Machine1	2.000120
Machine2	2.045230

thx, was a copy paste error
