Question

Can I build a

vector<vector<int> >

using Repetitive sequence constructor?

I know I can build one like

vector<int> v(10, 0);

but I dont know how to build a vector of vector using this same method. Thank you!

Answer 1

Just pass it a vector as the second parameter:

// 10 x 10 elements, all initialized to 0
vector<vector<int> > v(10, vector<int>(10, 0));
