Even there, it gives a warning and it is : questionable whether the program produced executes as required by the : standard (it returns a nonzero return code to the command processor : instead of 0 which is normally used for successful execution under : Windows NT). Just note, that the program posted by Bjarne Stroustrup is standard conformant *AND* returns EXIT_SUCCESS (which is defined to be 0). That is, it is completely correct. According to the standard, that is... The point here is the special exception for the function 'main()' saying that floating off the end of the function 'main()' is equivalent to exiting the function with 'return 0;'. However, this is a special exception holding only for 'main()'. Floating off the end of any other function returning something different than 'void' resutls in undefined behavior. -- I am a realistic optimist - that's why I appear to be slightly pessimistic --- [ comp.std.c++ is moderated.
