C++ multi-D vectors

Question

which c++ standard allows the declaration of a multi - dimensional vector in a class in header file and its population in the cpp file? my ide shows weird errors when I try that.

Answer 1

#include <vector>
...
//2-D vector of vector

vector<vector<dataType> > mVector;

vector<dataType> mRow;
mRow.push_back(data);
mRow.push_back(data);
mRow.push_back(data);

mVector.push_back(mRow);
mRow.clear();
....

continue to push vectors onto the 2-D vector.
you can access them as mVector[0][0]
