Well that's simple enough. You don't need to do any tricky parsing if there won't be commas embedded in a field.

What's the extent of your CSV format? Is it just a bunch of fields separated by commas, or can the fields contain commas as well? A full CSV format means you need to do some tricky quotation parsing...

No. If you're too lazy to do it then you deserve a failing grade.

Hey, the code is correct, so you're ahead of most of the tutorials on the web these days. ;)


Your site is bookmarked. I'll consider joining.

You're thinking too hard. :)

The simplest example is passing an object by value:

1) No, a structure's members are public by default, so anyone can access them. Dave put the structure in main to limit its scope to main. Consider this:

In that situation, you make the operator inline. The correct way to define it outside of your class is way too awkward to be practical:

Clearly. You have serious design problems by using inheritance instead of containment for this project. It's much simpler if CartesianPoint (aside from being more...

operator<< doesn't need to be a friend since you only use the public interface of array in it. A non-member function only needs to be a friend if it has to have access to a classes private or...

I don't think this is the right forum for your question, unless you plan on writing this program in C or C++.

Okay, what do you have so far?

That's because it's not allowed there. :rolleyes: Using static to qualify functions is deprecated anyway, use an unnamed namespace instead:

namespace {
template <> double ToDouble( double...

template <> double ToDouble( double source )
{
return source;
}

>> (certainly not C or C++).
It looks like Managed C++. But I agree that this question would be better asked in a .NET forum.

You need to include <iomanip> for setprecision().

This is a classic trade-off, and unfortunately, one that only you can decide.

Anytime you need to split off into one or more separate paths, you're looking at a switch or if chain.

Yes, very different. <fstream> is a standard modification of the prestandard <fstream.h>, where all of the classes are turned into template classes and a...
