[Dev-C++] Second STL example has a problem...

[Daniel G. <sp...@ho...>]

It's annoying because the examples don't show what headers to add nor does 
it say about using namespace std (I'm going with Ioannis' theory about 
explicitly stating std:: in my code).

This line is causing the problem in VC++ 6.0

std::vector<std::string> StrVector(Itr, EndOfFile);

where Itr and EndOfFile are members of my class LineIterator

I'm told by the compiler that Itr cannot be converted to an unsigned int... 
thoughts?

class definition:


#include <iostream>
#include <algorithm>
#include <string>

class LineIterator
{
public:
	std::istream* In;
	std::string Line;
	bool IsValid;

	/* Inlined function Read() is
	   used to check for a non-null
	   pointer and then gets user
	   input. If non-null input the
	   user has entered valid data.
	*/
	void Read()
	{
		if (In)
		{
			std::getline(*In, Line);
		}

		IsValid = (*In) ? true : false;
	}

	typedef std::input_iterator_tag IteratorCategory;
	typedef std::string ValueType;
	typedef ptrdiff_t DifferenceType;
	typedef const std::string* StrPtr;
	typedef const std::string& StrRef;

	/// Constructor
	LineIterator() : In(&std::cin), IsValid(false){}

	/// Overloaded constructor.
	LineIterator(std::istream& IStrmObj) : In(&IStrmObj) { Read(); }


	/**
	 * @Group OperatorOverrides
	 * The operator overrides for the LineIterator class.
	 */

	// Operator override for the * operator.
	StrRef operator*() const { return Line; }

	// Override the indirection operator
	StrPtr operator->() const { return &Line; }

	// Override the increment operator
	LineIterator operator++()
	{
		Read();
		return *this;
	}

	LineIterator operator++(int)
	{
		LineIterator Temp = *this;
		Read();
		return Temp;
	}

	bool operator==(const LineIterator& LineItrObj) const
	{
		return (In == LineItrObj.In && IsValid == LineItrObj.IsValid) ||
			   (IsValid == false && LineItrObj.IsValid == false);
	}

	bool operator!=(const LineIterator& LineItrObj) const
	{
		return !(*this == LineItrObj);
	}

	// End of group.
};
