object member variables.

[claire.bell1]

Hi,
Im making an othello game project and ive got to the point where the basic
game is done, but i need to add an intro and some way of deciding who you
play against.
My current structure is:
There is a main class othelloProgram which is created in the main method.
I want the othelloProgram to be in 3 main states, intro, game or newgame.
othelloProgram .: has an int variable state and the method SetState is
passed to the objects it creates.
To make a game an othelloProgram has 2 objects of type player and 1 of type
othelloGame, othelloGame's constructor needs to be passed pointers to the
players. othelloProgram also has an object of type intro.
Initially I do not want the othelloGame or players to be created, their
construction is dependant on the execution of the intro object, however the
constructor forces me to make them which causes all kinds of errors.
Also when intro eventually does run, i need to reconstruct the player and
othelloGame objects.

Is there any way to construct a class without constructing its member
objects? Also how do you destroy and remake an object from a member method?

Thanks for any help you can give,
Vipa

If you declare the member objects as pointers to objects, then you can
just initialize the pointers to 0 instead of instantiating the
objects.

Instead of this, try adding clear() and init() type methods to your
class which reset & initialize the state of your object.
