Question

So, im trying to create a 3 dimensional 5x3x2 vector, using the vector lib and saving the number 4 in every node.

Thats what im trying:

vector<vector<vector<int> > > vec (5,vector <int>(3,vector <int>(2,4)));

for a bi dimensional 5×8 saving the int 6 in every node, this works:

vector<vector<int> > vec (5,vector <int>(8,6));

Answer 1

You almost got it right — the second nested vector should be vector<vector<int> >, not just a vector<int>:

vector<vector<vector<int> > > vec (5,vector<vector<int> >(3,vector <int>(2,4)));
