Compiling error on my simple STL spell-checker.

[George2]

Hi, everyone!

Here is my simple STL program, it is a spell-checker.
The program copy every word of text to output
that is not in the dictionary. I have added all the source
codes and error messages below. My IDE is VC6.0.


Source Codes:

--------
#include <iostream>
#include <algorithm>
#include <cstring>
#include <vector>
#include <fstream>

using namespace std;

template <class bidirectional_iterator, class T>
class nonAssocFinder {
public:
nonAssocFinder(bidirectional_iterator begin,
bidirectional_iterator end) :
_begin(begin), _end(end) {}

bool operator() (const T& word) {
return binary_search(_begin, _end, word); }

private:
bidirectional_iterator _begin;
bidirectional_iterator _end;
};


void main()
{
typedef vector<string > dict_type;

ifstream dictFile("dict.txt");
ifstream wordsFile("words.txt");

dict_type dictionary;

copy (istream_iterator<string>(dictFile),
istream_iterator<string>(),
back_inserter(dictionary));

remove_copy_if (
istream_iterator<string>(wordsFile),
istream_iterator<string>(),
ostream_iterator<string>(cout, "\n"),
nonAssocFinder<dict_type::iterator,
dict_type::value_type>
(dictionary.begin(), dictionary.end()));
}

--------

How to resolve the trouble?


Thanks in advance,

George2,

The warnings are harmless, nevertheless you can remove the warnings in VC6 with

#pragma warning(disable : 4786)

placed at the top of your C++ or header file.

I think the error is of some concern. You might have to write a global operator >> for some user-defined type in the class. I did not really study the example very closely and can not clearly indicate a solution.

Chris.

dude_1967 is right about the warnings. As far as the error is
concerned, have you thought about "#include <string>" ?

Thanks, PaulWendt buddies!
