Thread: Help me with a program involving structs and struct pointers?

I am having a little problem with this program

Code:

#include<stdio.h>

void printstruct(struct patient *, int);

struct patient
{
  char id[8];
  int systolic;
  int diastolic;
  int ldlchol;
  int hdlchol;
};

int main(void)
{
  int i = 0;
  struct patient p[10];
  FILE *pat;
  if ((pat=fopen("patients.dat", "r")) == NULL)
    puts("Error reading file");
  else
    {
      while(!feof(pat))
	{
	  fscanf(pat, "%s %d %d %f %f", p[i].id, &p[i].systolic,
		 &p[i].diastolic, &p[i].ldlchol, &p[i].hdlchol);
	  i++;
	}
    }
  fclose(pat);
  printstruct(p, i);
  return 0;
}

void printstruct(struct patient *patientPtr, int i) 
{
  int x = 0;
  FILE *patrpt;
  if ((patrpt=fopen("patient.rpt", "w"))==NULL)
    puts("Error writing to file");
  else
  {
    fprintf("%20s", "Patient's Report");
    fprintf("%s", "Patient ID Blood Pressure  Cholesterol Ratio\n");
    for (x = 0; x <= i; x++)
    {
      fprintf("%8s %3d\\%3d %9f", patientPtr->id, patientPtr->systolic,
	      patientPtr->diastolic,(patientPtr->ldlchol/patientPtr->hdlchol));
    }
  }
  fclose(patrpt);
}

The errors i am getting are:
"patte.c", line 50.13: 1506-280 (W) Function argument assignment between types "
struct {...}*" and "unsigned char*" is not allowed.
"patte.c", line 51.13: 1506-280 (W) Function argument assignment between types "
struct {...}*" and "unsigned char*" is not allowed.
"patte.c", line 54.15: 1506-280 (W) Function argument assignment between types "
struct {...}*" and "unsigned char*" is not allowed.


those are coming from these lines

Code:

  else
  {
    fprintf("%20s", "Patient's Report");
    fprintf("%s", "Patient ID Blood Pressure  Cholesterol Ratio\n");
    for (x = 0; x <= i; x++)
    {
      fprintf("%8s %3d\\%3d %9f", patientPtr->id, patientPtr->systolic,
	      patientPtr->diastolic,(patientPtr->ldlchol/patientPtr->hdlchol));
    }
  }

Thanks

thanks buddy
