Thread: Inventory records

I fixed the hfPtr, it was the others that I thought were declared in the prototype. Its now giving me an error that says writePr is being used without having been initialized but I thought that this had initialized it.

Code:

/* create formated text for printing */
void textFile( FILE *readPtr )
{
	FILE *writePtr; /* hardware.txt file pointer */

	/* create hardwareData with default information */
    struct hardwareData hardware = { 0, "", 0,0.0 };

    /* fopen opens file; exits if file cannot be opened */
	if ((hfPtr = fopen( "hardware.dat", "rb+" )) == NULL ) {
		printf( "File could not be opened.\n" );
	} /* end if */
	else{ 
		rewind( readPtr ); /* sets pointer to begining of file */
		fprintf( writePtr, "%-6s%-10s%-8s%-8s\n",
			"Record#", "Tool name", "Quantity", "Cost" );

p.s. feof is what is used in my book so thats why I used it.
