Tutorial :creating a 2D array of vectors



Question:

I have been trying to create a 2D array of vector for a game. Here is an example of what I am doing.

struct TILE {      int a;      char b;      bool c;  };    TILE temp_tile;    std::vector<TILE> temp_vec_tile;  std::vector<std::vector<TILE>> tile;      for (int x = 0; x < 10; x++) {      for (int y = 0; y < 10; y++) {        temp_tile.a = x;      temp_tile.b = "a";      temp_tile.c = false;;        temp_vec_tile.push_back(temp_tile);      }        tile.push_back(temp_vec_tile);  }    // Why does this not work?  int x = tile[3][5].a;  

Note: I don't want to use Boost for this.

Thanks


Solution:1

You are not clearing the internal vector each time. Probably what you want is to put the internal vector declaration inside of the first for loop.
