Something like this :

    typedef vector< vector<int> > twodimarray;
    
    unsigned int dimx = 5, dimy = 10;
    
    twodimarray v(dimx);

    for(twodimarray::iterator i = v.begin(); i != v.end(); ++i)
	i->reserve(dimy);


Although most of the time you're probably better of with just

    typedef vector< vector<int> > twodimarray;
    twodimarray v(dimx);

and then store values in it with

    v[i].push_back(intValue);
