Map iterator to string

[Micheal Smith]

I'm looking for a good method to convert a map::iterator to a
std::string. I've tried googling for a while, but haven't come up with
much. Perhaps I'm kludging things here. Either way any advice would
be greatly appreciated.

What are you hoping to get from the conversion?

I have a member function that searches a map for a key. The value tied
to the given key should be a std::string. It just seemed like a better
idea to return the original std::string, than simply an iterator.

What's wrong with using iterator->second?

Your original post is very poorly written. You are asking in your
original post how to *convert* a map::iterator (what kind of map?) into
a std::string. What does that even mean? Are you trying to generate a
string from the value of the iterator? Are you trying to cast the
iterator into a string? What?

Seemingly what you have is a std::map<someth ing, std::string>, and you
have an iterator pointing to an element of this map, and you want to
dereference the string at that position in the map (which happens with
"yourIterat or->second", which is probably the answer you are looking for).

You should be much more specific when you ask such questions.

or:
my_iterator->first

for std::map<std::s tring, anything>;
