Proper syntax for declaring a vector of vectors using STL

[javaman99]

vector<vector<Edge> > temp1(size);


this makes a vector which contains size vectors. The problem is the internal vectors are all of the defualt stl size. How would I properly make it so that the internal vectors are the same size as the one holding them, essentially creating a square matrix.

The easiest way would be to create another class that contains your type of vector<Edge> and make a vector of that.

or you could push_back() size items into each of the inner vectors...

Argh! Sorry, there is an easier way than what I said.

int i;
vector< vector<Edge> > temp1(size);
for(i=0; i<FOOBAR; i++) {
vector<Edge> inner_tmp(inner_size);
//Do stuff to inner_tmp here...
temp1.push_back(inner_tmp);
}

That's going to be the easiest way to set the sizes of the inner vectors.

Actually the easiest way is

vector <vector<Edge> > temp1(size, size);

I had to ask around to get that one though but it works
