From: VLA <verrola@yahoo.com> To: nathan@gcc.gnu.org, gcc-bugs@gcc.gnu.org, gcc-prs@gcc.gnu.org, nobody@gcc.gnu.org, gcc-gnats@gcc.gnu.org Cc: Subject: Re: c++/8285: default arg doesn't work in vector Date: Sat, 19 Oct 2002 08:50:40 -0700 (PDT) Thanks nathan, the vector constructor use the copy constructor to create the other n-1 objects of the vector when called with vector<T>(n) but it created an instance for each element for vector<T>(n, v). i saw one object was created, i just couldn't figure out why the rest weren't. Thanks, you r the man. but Nathan, i can't remember reading about this in the C++ Programming Language. Is this how it should work? I know, my class should have a copy constructor if it has pointer members, i just didn't think the vector would use it. Thanks again. .v --- nathan@gcc.gnu.org wrote: > Synopsis: default arg doesn't work in vector > > State-Changed-From-To: open->feedback > State-Changed-By: nathan > State-Changed-When: Sat Oct 19 08:25:13 2002 > State-Changed-Why: > I suspect coding error.
