[color=#000000:post_uid0]What's wrong with this code?

[b:post_uid0]ZStreamable.hpp[/b:post_uid0]
[code:1:post_uid0]namespace zilla {
class ZStreamable;
}

std::ostream& operator<<(std::ostream& out, const zilla::ZStreamable& obj); // line 13

namespace zilla {
class ZStreamable {
public:
ZStreamable ();
virtual ~ZStreamable ();

virtual void render (std::ostream &out) const = 0;

friend std::ostream& operator<<(std::ostream& out, const zilla::ZStreamable& obj); // line 23
};
}[/code:1:post_uid0]

[b:post_uid0]PageFooter.hpp[/b:post_uid0]
[code:1:post_uid0]namespace zilla {

[color=#000000ost_uid0]Yeah, all day today I've been getting a runtime error that sounded something like this:

Line: 176
Error: Unterminated String Constant

Now if I had some clue on how to use C++, I'd know what that would mean...but my programming is limited to Visual Basic and Java.

I figure that the error will be fixed when everything flips back to forwards which is the inverse of the backwards way became when the calender flipped forwards from yesterday to today, and will be rectified when the calender flips forward to the...[okay, you get the picture].
:smile:

EDIT: Did I mention that I only know a very limited amount of Java?[/colorost_uid0]

[color=#000000ost_uid0]Add a " at the end of the line.

Unterminated string constant means you didn't close a string somewhere.[/colorost_uid0]

[color=#000000ost_uid0]Maybe you could copy it all into Word, then run a text search to see if everything you want spelled the same *is* spelled the same. That is, tell the program to search for "std:stream&" and see if it skips over any of them. Why strain your eyes looking for missing :'s?[/colorost_uid0]

[color=#000000:post_uid0]Actually, I've already copy/pasted the function definition into the friend definition, and removed unnnecessary scopes. Didn't help any. I think my use of friend is just wrong, but it looks right.[/color:post_uid0]

[color=#000000ost_uid0]ooo C++. I should know this since I took 2 years of it. I think the previous people already solved it.[/colorost_uid0]

[color=#000000ost_uid0]Okay, I found it. Subtle bug: the declaration inside ZStreamable declared zilla:perator<< to be a friend, but the actual operator was :perator<< (no namespace).

Besides which I've switched back to cgicc::MStreamable instead of my custom ZStreamable, because I was able to work out my issues from that.[/colorost_uid0]
