Hi i would like to know how to declare a multi dimensional vector and then later initialize its size.
normally id declare and init a vector like :
vector< vector<Tile> > tiles(50, vector<Tile>(50));
creating a multidimensional vector with 50 rows and 50 cols.
i know how to declare a vector and not init its size :
vector< vector<Tile> > tiles;
but how can i later declare the number of rows and columns.
