Overloading << generates problems

Hi all,

I have the following code:
class test {
test(const std::string *n) : name(n) {}
virtual ~test() {}

const std::string * getName() { return name; }

const std::string * name; ///< Variable name.


std::ostream& operator<<(std: :ostream& s, const test& v) {
return s << v.getName();

And I get when I try to compile:
common/test.cc: In function `std::ostream& operator<<(std: :ostream&,
const test&)':
common/test.cc:5: error: no matching function for call to `test
::getName() const'
common/test.h:14: error: candidates are: const std::string*
test::getName() <near match>
make: *** [test.o] Error 1

Any ideas on where the problem is?

I know this isn't what you were asking, but your code makes me
nervious. Where does the memory for test::name get created? Is it on
the stack? or on the heap? Is the test class responsible for deleting
it or not? What about the default copy constructor that the compiler
generates, it's a shallow copy, is that what you want?...

I realize that this class may be used only for illustration purposes,
but IMHO it has a lot of potential problems.

Hi all, I'm having a problem and for illustration purposes I developed code that shows what the problem is about. However, any comment on the code which is not directly about this issue is surely welcome. I have 3 classes, A is abstract, B and C inherit from A and then I create a vector with B's and C's and print them. Of course, I overload << for each one of them. So it is as follows:

Hi, Describing this problem will be a bit long winded, but please bear with me: I've got three files in my project: permuts.h, permuts.cpp, and braids.cpp (some content from wich will eventually be moved into braids.h). Both cpp files include the h file. Permuts.h contains the Permutation class, for which I needed to overload <<. Doing this in that file caused an error(Duplicate definition I think - it occurs to

The following code compiles and runs. In my overloaded operator<<, I call Parent.stuff. I would expect it to call Child.stuff, since Child is the child class, but it does not. What am I missing, and how can I get it to call Child.stuff. Eventually I'll have different child classes, and I need it to call stuff() from the associated child class, not Parent.stuff. #include <iostream> #include <ostream> #include <string>

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
