Came across this cool approach to handling 2D arrays in C which I thought might be nice to share. The approach is basically using a 1d of size width*height of the array e.g: say we have a 1d array of our tiles enum: enum TILES tiles[TILES_WIDTH * TILES_HEIGHT]; we can just loop over it with a single index: for(int i = 0; i < TILES_WIDTH * TILES_HEIGHT; i++) { enum TILES tile = tiles[i]; // If we need the x and y values int x = index % TILES_WIDTH; int y = index / TILES_WIDTH; draw_rect(v2(x * tile_size, y * tile_size), v2(tile_size, tile_size), color); } if we want to index into a given x and y coordinate we multiply the y index by the width of the array and add the x index: tiles[y * TILES_WIDTH + x] I've found this approach has been useful for tile/grid based games EDIT: Thanks @Nick H for the suggestion
