Hello,
I have a question. I have the following construct:
std::vector < std::vector < std::vector< AsMarkerMatchMa trix >> >
m_matchMatrices ;
If I run a std::find on that I sometimes get the iterator to be some strange
number like -124224256, although I know there should not be a match. Usually
the iterator points to NULL, if there is no match.
Anybody experienced the problem? MS c++ 7.1
Also I get an "could not deduce template argument" error, if I do not
implement the == operator, although the parent class implements it.
Greetings, Peter

Show us a small compilable example that gives the
problem behavior.

Found the problem: I should compare with vector.end() to find out, if there
was a match, but for the second question I did not find an answer.

Please don't top-post.
We cannot answer your question until you provide
context (code).

Hi there,
We have a compiler specific issue which requires us to force template instantiation. This works fine. The problem comes
when I try using std:find() on vector. Since vector has no member function find() and I have to use std::find(). The
linker fails on unsatisified symbols in find().
I think this is because find() is a template...

In the documentation for std::find, it says:
find returns the first iterator i in the range [first, last)
for which the following condition holds:
*i == value.
However in my compiler's headers the implementation is:
template <class InputIterator, class T>
InputIterator find (InputIterator first, InputIterator last, const T& value)

I ahve a vector of doubles taht I need to extract values from. I was
just about to use the STL find() algo, but I have a couple of questions:
first: can you specify the tolerance threshold to match on doubles?
second: if yes, how may this be done (i.e. how many one specify the
tolerance threshold for comparing doubles?)
