Why does Object anObject; call the default constructor Object::Object(), but Object anObject(); doesn't? Instead, there really seems to be no call at all. best regards / Gruß Moritz Beller -- web http://www.4momo.de mail momo dot beller at t-online dot de gpgkey http://gpg.notlong.com Back to top Risto Lankinen Guest Posted: Mon Aug 30, 2004 12:23 pm    Post subject: Re: (default) constructor/object initializing problem Hi!

Instead, there really seems to be no call at all. Because "Object anObject();" looks like a function declaration to the compiler. Nothing is constructed really; instead the compiler will think that "anObject" is a function taking no arguments and returning an instance of "Object". - Risto - Back to top Moritz Beller Guest Posted: Mon Aug 30, 2004 1:25 pm    Post subject: Re: (default) constructor/object initializing problem On Mon, 30 Aug 2004 12:23:18 GMT "Risto Lankinen" <rlankine (AT) hotmail (DOT) com> wrote: Quote: Because "Object anObject();" looks like a function declaration to the compiler.

"anObject2" refers to a pointer //to the function. If you stick in brackets, as in: anObject().MemberFunc(); //then the function will actually be called //and the fullstop will access members of the //object returned from the function } -JKop Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
