}


And this is the error

On line 57 of division.cpp
'error: no match for 'operator<<' in out (&p)->std::_List_const_iterator<_Tp>::operator* [with _Tp = Project]()'|




I'm supposed to only edit the Project.h file for this problem. I'm sure its something to do with changing the operator but I can't seem to figure this out :l

Any help would be greatly appreciated and also, if you solve my problem, could you please explain to me what you did and why so I understand what I didn't before. Thanks for your help.

Declare operator<< in the header file.
VladTeppi (30)
Maybe I didn't specify, and for that I apologize. I continue to try to do that but I can't seem to do it properly.
clanmjc (666)
Since I don't see it, what does div.begin() return.

I thought I included the whole file but I must not have copied correctly. I have a few more files I can include if need be. The only other one that might be helpful would be division.h which I included above
clanmjc (666)
Thanks now it makes sense
'error: no match for 'operator<<' in out (&p)->std::_List_const_iterator<_Tp>::operator* [with _Tp = Project]()'|


See the list iterator part?

std::list<Project> begin() This is what begin returns.

}
VladTeppi (30)
I am currently not at my laptop to check it but Im fairly certain when I attempted to overload the operator, the original error disappeared but I received an error saying I was not able to overload it. I'll have to double check though to give you the exact error
VladTeppi (30)
As I expected, I get this error.

|53|error: `bool Project::operator<<(const Project&) const' and `bool Project::operator<<(const Project&) const' cannot be overloaded|

clanmjc (666)
Firstly don't overload the operator for your class. Make it a non-const non-member function like you did for Division.
VladTeppi (30)
Okay, thats helpful. Thank you. Now, I think I'm headed in the correct direction but ran across another error.

	      << p.getBudgetCode << "\t"
	      << "\n";
	  return out;
}



I put the operator in project.cpp and it looks like this (, starting on line 36).

I get these errors:

Z:\CS330\Assignment 1\project.cpp|36|error: 'Project::const_iterator' has not been declared|
Z:\CS330\Assignment 1\project.cpp||In function 'std::ostream& operator<<(std::ostream&, int)':|

Z:\CS330\Assignment 1\project.cpp|41|error: request for member 'getBudgetCode' in 'p', which is of non-class type 'int'|
||=== Build finished: 5 errors, 0 warnings ===|



Before I have it the way I posted, the operator functions p.getTitle, p.getDivision and such all had () at the end of them but that did not fix it.

ex: p.getTitle() << .......


Any more guidance? Thank you guys for helping me. You are a godsend.
