C++ Map of Vector of Structs?

So here's a snippet of my code:


    struct dv_nexthop_cost_pair
    {
      unsigned short nexthop;
      unsigned int cost;
    };



map<unsigned short, vector<struct dv_nexthop_cost_pair> > dv;

I'm getting the following compiler error:

error: ISO C++ forbids declaration of `map' with no type

What's the proper way to declare this?

use typedef

typedef std::map<unsigned short, std::vector<struct dv_nexthop_cost_pair> > dvnexthopemap;
dvnexthopemap db;

Either you forgot to #include the right headers or didn't import the std namespace. I suggest the following:

#include <map>
#include <vector>

std::map<unsigned short, std::vector<struct dv_nexthop_cost_pair> > dv;
