hi,
is there an efficient for to insert the elements of a 2d array into a vector of vectors?
I have
thanks for the helpCode:vector< vector <int> > Points for (i = 0; i < n; i++ ) Points.push_back(vector<int>(d)); int Matrix[n][d]; //populate matrix.... //How to load the data in the Matrix into the vector of v. Points? // is there something better than //iteratation through: Points[i][j] = Matrix[i][j]
You could use iterators, but that would be basicly the same thing.
You might be able to find a vector constructor to simplify things; from http://www.fredosaurus.com/notes-cpp...er-vector.html
My suggestion is to replace the code that "populates matrix" with code that populates Points, if possible.Constructors and destructors
vector<T> v; L
Creates an empty vector of T's.
vector<T> v(n);
Creates vector of n default values.
vector<T> v(n, e); L
Creates vector of n copies of e.
vector<T> v(beg, end); L
Creates vector with elements copied from range beg..end.
v.~vector<T>(); L
Destroys all elems and frees memory.
