std::find

[Peter Meier]

Hello,

I have a question. I have the following construct:

std::vector < std::vector < std::vector< AsMarkerMatchMatrix >> >
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.

Show a small example that gives this error.

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).
