Composition Vs Inheritance

[anagha patankar]

Hello everybody ,
At the onset with due respect to all - I would like to state that I am not interested into getting into the details pertaining to UML notation .

Have tried googling around - and the only reason that I could understand
was that in case of inheritance it is difficult to change the
superclass method signature ( would cause a break in implementation classes )

so question is - is this the only reason that one should choose composition ?
Agreed that one must make a judgemental call - could someone point me to some
articles that compare when to use composition , when not to and similarly regarding inheritance .

Finally - is this the right forum for such questions ?

Thanks,
-anagha
