Need some help initializing a pointer.

I'm need some help initializing a pointer. Below is a segment of my code that I'm working on. The pointer that I need help with is subjectPtr.

Code:

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


struct SUBJECT
{
	int fam;
	int id;

};

typedef struct SUBJECT DATA;
DATA *HT;
DATA *subject_array;
int num_elements = 0;
int num_allocated = 0;

void readInputFile(FILE *input)
{
	DATA *subjectPtr;
	
	void *temp;

	while(fscanf(input,"%d\t%d", subjectPtr->fam, subjectPtr->id) != EOF)
	{
		.
		.
		.	 	
	}
}
.
.
.

Do you want to declare an instance of DATA, and then assign the ptr to that address? Your DATA pointer logically needs an instance of a DATA struct to point to, does it not?

What do you mean?
