VC++ map

[GOBLIN-85]

Hi guys,

I'm having problems with using map in VC++, here is the function that I'm making:

void GLMesh::convertToDiffCoord(Mesh *m)
{
	//get the pointer to the list of pointers to all vertices
	list<Vertex*>* v = m->get_vertices();

	//initialize a map that will map each vertex pointer with an unique key
	map<int, Vertex*> VMap;

	//initialize iterator for the pointer list v
	list<Vertex*>::iterator vi;

	//iterate through the list and map each member in the list with a unique value
	for (int i=0; i<v->size(); i++)
		for(vi = v->begin(); vi != v->end(); vi++)
			VMap[i] = v->[i];
}

I keep getting the error :"syntex error '[' ", any idea what's wrong?

You probably want this:

VMap[i] = v[i];

v is a pointer, and pointers can be treated as array names.

-> breaks out class members; its used for a pointer to a multi-field variable.
[] is how you get to a location in an array of the same object.

and you can mix and match, an array of classes might give you
thingy[10]->field = 3;

you can also use * instead of [] to make you code uglier, you see this in C code or in c++ code written by C programmers.
