Need help in a c programme - High Level Programming

user_prady · #1 02-14-2008

Dear Friends,

I ve two text files like
re_im.dat

Code:

  13.7663000000         5.9572200000
  10.2682000000        10.9345000000
  5.0810700000        14.1132000000

two real values per row
Sarf.dat

Code:

127 128 128 128  71 0
128 128 128 128  71 0
128 128 128 128  71 0

This is having 6 unsigned values per row.

I ve function in c which does some calculation depending on these inputs
from the above two file

The first two arguments to my c function are input from the file re_im.dat,
next 6 values to the function are from file Sarf.dat

the next two arguments to the function are output from that function to another function .

My problem is to read values and send as a pointer to the function..

The function is as below..

Code:

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

typedef unsigned int U;
typedef struct {U c; U d;} vec32;

void rf_model(double *input_re, double *input_im, vec32 *lsts, vec32 *vgagain, vec32 *dcout1i,\
 vec32 *dcout1q, vec32 *dcout2i, vec32 *dcout2q, double *adc_input_re, double *adc_input_im){

}

If my explanation is not clear pls let me know ..

need help badly..

regards,
Prady

Hey,
Where do you read in those values? Can you print them (using prinf()), so you can be sure?
If the problem really is that you don't know how to read those values, check the function fscanf() or fgets().

Well, you could read the files with fscanf() and then store the values in to some array, which you can pass to your function.
