help reading file in and sorting it

[jrjan1]

I thought I understood how to do this, but have spent all weekend and haven't gotten anywhere, can someone please help?? I'm desparate.

This is my main: partNum and dept are strings, price is a double.

while (!inData.eof())
{
      readDataItem(inData, partNum, dept, price);
}
 
 

After I read the file in how can I get it into separate arrays so I can sort it?

This is my header file

class Item
{
    friend ostream& operator<<(ostream& cout, Item& );
 
public:
    void print() const;
 
    Item(string* p, string* d, double* pr);
 
    Item();
 
private:
    string* part;
    string* deptNo;
    double* itemPrice;
};
 

This is my .cpp file

#include "Item.h"
 
Item::Item(string* p, string* d, double* pr)
{
    part = p;
    deptNo = d;
    itemPrice = pr;
}
 
Item::Item()
{}
 
ostream& operator<<(ostream& osObject, Item& i)
{
    osObject<<i.part;
    osObject<<" ";
    osObject<<i.deptNo;
    osObject<<" ";
    osObject<<i.itemPrice<<endl;
return osObject;
}

I suspect that declaring you member variables as pointers

    string* part;
    string* deptNo;
    double* itemPrice;
 

is a mistake. You are going to have to do a lot of memory operations to support these pointers and I think you could use actual data members rather than pointers.

You say you are having trouble reading a file but you havn't given the file format.
