What's wrong?

[xx1182]

I'm making a simple Snake game in SDL, but when i'm making the grid isn't supposed to go like this:

void SnakeGame::SetGrid()
{
    SDL_Rect filler{0,0, 16, 12};
    for(int i = 0; i < 64;i++)
    {
        for(int j = 0; j < 64; j++)
        {
            if(grid[i][j] == Nothing)
            {
                SDL_SetRenderDrawColor(mainred, 0, 255, 0, 255);
                SDL_RenderFillRect(mainred, &filler);
                filler.y+=filler.h;
            }
            if(grid[i][j] == Food)
            {
                food->myfood.y*=12;
                SDL_SetRenderDrawColor(mainred, 0, 0, 255, 255);
                SDL_RenderFillRect(mainred, &food->myfood);
                std::cout << food->myfood.x;
            }
        }
        filler.y=0;
        filler.x+=filler.w;
    }
}
