Re: [Mingw-users] C++ & constructor question

[Jose F. <jrf...@em...>]

Making

>     Foo f();

is a common mistake. This declares a function f with no arguments that
returns Foo.

what you want is

>     Foo f;

wich invokes the default constructor.

never call Foo's constructor (and destructor of course...)
