Thread: I/O problem

Hey everyone! Been a while since I have been on the board, but so far I have had no problems..lol Well this semesterI am learning C++ and ran into a bit of trouble.

The program is supposed to read from the supplied file and then count how many files are present. The problem is though that everytime I run it I get a coredump.

Any advice?

Code:

#include<iostream.h>
#include<stdio.h>

#define NAME_LEN 50

typedef struct nodetag{
	int recordNum;
	char name[NAME_LEN+1];
	int quantity;
	float unitPrice;
}Hardware;

FILE *fp;

int count(void);
char menu(void);

int main()
{
	system("clear");

	int count2=0, c=0;

    if((fp = fopen("hardware.dat", "r")) == NULL)
		cout<< "Error to open the file";

	else
	{

	cout<< "\n\tTotal counts: " << count();

	}

	return 0;
}

int count(void)
{
	int c=0;
	int recordNum, quantity;
	char name;
	float unitPrice;

	fscanf(fp, "%d%s%d%f", &recordNum, name, &quantity, &unitPrice);

	while(!feof(fp))
	{
		c++;
		fscanf(fp, "%d%s%d%f", &recordNum, name, &quantity, &unitPrice);
	}

	return c;
}

Code:

>int count(void)
>{
>	int c=0;
>	int recordNum, quantity;
>	char name;

It looks like you wanted:
char name[NAME_LEN+1];
