I'm busy learning linked lists and was following a video tutorial since my text book doesn't make much sense to me. Anyway, I've copied all of the code from the video, but I cannot seem to compile it. I keep on getting the following error below relating to one of my classes. I've watched and re-watched the video, but I cannot seem to figure out where I went wrong - please help.

What are you using to compile this?

I'm using codeblocks.

friend ostream& operator<<(ostream  os, const Contact&c);

       ostream& operator<<(ostream& os, const Contact&c)
Spot the difference

Thank you so much! Compiles perfectly now.

I still need to learn what type of errors to look for :) and even then, just to have a second (or third) pair of eyes going over the code helps a lot!
