    Storing breakout bricks in an array SDL

    And can I not initialize the data values of the members of the array using the parameterized constructor?

    Okay Okay! I get it. Thanks! It worked!

    Storing breakout bricks in an array SDL

    I had to add the default constructor because the compiler wouldn't let me initialize an array otherwise.

  6. So I just started game programming and I was working on a game like breakout where there is a paddle and a set of bricks that can be destroyed using the ball.I am using SDL and C++ to make the game. I can't figure how out how to implement the set of bricks in the game.I have a class "Brick" .I use a constructor to initialize the values of the SDL_Rect for the brick and also the surface image for the brick. Also I use a show function to show the brick using the SDL_BlitSurface function. Now I declare an array say "brick a[20];" and even if I don't call no function or constructor , on compiling it fails to compile and gives an error. I am using Visual studio 2010.
