The following programme i just need to read from a file about choclate information for a shop. Then if i want to update the stocks i have to do it in a programme. But when I compile it comes segmentation fault(code dump).
1. I need to know why i got this error.
2. I have 20 choclate stock information. I don't know how to read and update the information.
It would be grat pleasure if you can help me for this programme.

Here is the code:

#include <iostream>
#include <fstream>
#include <cstring>

using namespace std;

struct Supplier
{
	char sname[50];
	char saddress[50];
	char sphone[50];
};

struct Chocolate
{
	char cname[100];
	char ctype[100];
	char qty[100];
	char ppp[100];
	Supplier supply;
}choco[20];

int main()
{
	int num;
	ifstream infile;
	infile.open("choc.txt");

	
    if(!infile.eof())
	{
		infile>>num;
			for(int i=0; i<num; i++)
			{
				
				infile.getline(choco[i].cname,50,'\n');
				infile.ignore();
				infile.getline(choco[i].ctype,50,'\n');
				infile.ignore();
				infile.getline(choco[i].qty,50,'\n');
				infile.ignore();
				infile.getline(choco[i].ppp,50,'\n');
				infile.ignore();
				infile.getline(choco[i].supply.sname,50,'\n');
				infile.ignore();
				infile.getline(choco[i].supply.saddress,50,'\n');
				infile.ignore();
			

				cout<<choco[i].cname<<endl;
				cout<<choco[i].ctype<<endl;
				cout<<choco[i].qty<<endl;
				cout<<choco[i].ppp<<endl;
				cout<<choco[i].supply.sname<<endl;
				cout<<choco[i].supply.saddress<<endl;
				cout<<choco[i].supply.sphone<<endl;
			}
			
	}
	
			
			
	return 0;
}

Come ON! You've been around here long enough now to know to use CODE TAGS!!!

When you COMPILE it, it dumps core, or when you RUN it?

Each chocolate’s information should be kept in a struct containing the following information:

– chocolate name
– description
– quantity
– price per piece
– supplier information (kept in another struct containing name, address, and contact number)

You need to check that your file opened correctly. Your program runs successfully for me, no segmentation fault.

What do u mean by open correctly.

[jimblumberg]

You are trying to open a file for input. If the file doesn't exist then this opening fails. You need to insure that your file opened correctly.

ifstream fin("YourDataFile");
// Check to insure the file opened correctly.
if(!fin)
{
   // The file failed to open.
   // Do something.
}
