stl multimap

[RubyNet]

Hi Experts,

i want to delcare a multimap int -> char*
is it possible ?
currently i declare it like this
typedef std::multimap< int, string , std::less< int > > mmid;
mmid collocs1;

i get an error:
c:\documents and settings\user\my documents\courses\textmining\tdm\tdm-0.0.1\vcpp\flexfeatureextraction\freqtest.cpp(68) : error C2039: 'value_types' : is not a member of 'multimap<int,class std::basic_string<char,struct std::char_traits<char>,class

at the line:
collocs1.insert( mmid::value_types( 30, &quot;hello&quot);

what could be possibly be wrong with the declaration or i have to enclose the char*
in a class and then insert it ??


Thanks in advance.

Ruby

std::multimaps and std::maps contain pairs, not individual elements.

The following should work for you...

multimap<int, string, less<int> > mmid;
string temp = &quot;hello&quot;;
mmid.insert(make_pair(30, temp));

That's true.

However, mmid::value_type is an std:air. So the original post was correct, there was just a typo (value_type, not value_types).

My bad - didn't study the post too closely

No problems. Your answer was perfectly right; I was just pointing out some extra info.
