Thread: Not returning correct results

All my calculations are coming up under the Female columns. They're in the correct age and lead type, but all the males are being calculated as females! What am I doing wrong?

Code:

#include <stdio.h>
#define MAXRECORDS 4

struct record
{
   char gender;
   int age;
   int lead;
};

void read_file(struct record rec[]);
void calculations(int c[], struct record rec[]);
void print_report(int c[], struct record rec[]);

int main()
{
   int c[36] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
   struct record rec[MAXRECORDS];
   read_file(rec);
   calculations(c, rec);
   print_report(c, rec);
}

void read_file(struct record rec[])
{
   FILE *fpin;
   int i;

   fpin = fopen("custsurvey.dat", "r");

   if(fpin == NULL)
   {
      printf("Error opening file");
   }
   else
   {
      for(i = 0; i < MAXRECORDS; i++)
         fscanf(fpin, " %c  %d %d", &rec[i].gender, &rec[i].age, &rec[i].lead);
   }

   fclose(fpin);

   return;
}
