Why not use STL:vector? So easy, and you don't need to delete the vector.

int rows = 100;
int cols = 200;
vector< vector<int> > f(rows, vector<int>(cols));
f[rows - 1][cols - 1] = 0; // use it like arrays

You can also initialise the 'arrays', just give it a default value

const int DEFAULT = 1234;
vector< vector<int> > f(rows, vector<int>(cols, DEFAULT));
