Can I use vector as index in map structure in c++?
- by tsubasa
I attempted to do something like this but it does not compile:
class point
{
public:
int x;
int y;
};
int main()
{
vector<point> vp1;
vector<point> vp2;
vector<point> vp3;
map < vector<point>, int > m;
m[vp1] = 1;
m[vp2] = 2;
m[vp3] = 3;
map < vector<point>, int >::iterator it;
for (it=m.begin(); it!=m.end(); it++)
{
cout<<m[it->first]<<endl;
}
return 0;
}
