I am using Dev-C++ and lambda, the program is the following:

...................

typedef std::map<int, int> IIPrimemap;
IIPrimemap primemapvec;

...............
 bind(&IIPrimemap::lower_bound, primemapvec,3);

...................

But the complier told me that:

cannot resolve overloaded function `lower_bound' based on
   conversion to type `unsigned int'

but when I type :

bind(&IIPrimemap::count, primemapvec,3);

it is accepted by the complier.

I searched through the SGI STL help file,and find that there are two types of return value for IIPrimemap::lower_bound: iterator and const_iterator. And there is only one type of return value for IIPrimemap::count: size_type.Maybe that is the reason.

But how can I solve the problem. Can anyone with kindness help me?
