Thread: Array of structs

Code:

struct test
{
  int r, i;
};

/* Read n from the file */
struct test *t = malloc ( n * sizeof *t );
for ( i = 0; i < n; i++ ) {
  /* Fill the array up to t[n - 1] */
}

-Prelude

Code:

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

typedef struct
{
 int x;
 int y;
} COMPLEX_NUMBER;

int main (void)
{
 int i, counter;
 FILE *fp;
 COMPLEX_NUMBER *pCN;

 fp = fopen ("datafile", "r");

 fscanf (fp, "%d", &counter);

 pCN = malloc (counter * sizeof (COMPLEX_NUMBER));

 for (i = 0; i < counter; i++)
  fscanf (fp, "%d%d", &(pCN + i)->x, &(pCN + i)->y);

 for (i = counter - 1; i >= 0; i--)
  printf ("%5d%5d\n", (pCN + i)->x, (pCN + i)->y);

 fclose (fp);

 return 0;
}

I have never understood why the hell people do everyone's entire homework project for them... The only time I do this, the code is an "alternate" way of doing it, that either (a) they wouldn't understand, (b) their teacher wouldn't accept the code for a grade, (c) the teacher would know that there's no way in hell the student wrote this code...
