Both your compiler and I have been telling you what is not matching up. But you don't seem to understand that there is a difference between a char and a char array. You need to study the tutorials I provided and if you still don't understand the differences, ask specific questions.
1> There is no context in which this conversion is possible
The function tutorials linked in my signature are also very good about how to create and use a function. The only difference between a friend function and a regular stand alone function is that the friend function has access to all members of the class a stand alone function only has access to the public members of your class.
