error: expected primary-expression before 'char'

		
		 cout << "What do you wish to append?"
		 << endl;
		 cin  >> line;
		 list::append(char line[]);
	}

class list

{

	public:

		  list();

		  ~list();

		  int append(char line[]);

		  int remove(char line[]);

 

Now, the problem that it is referring to is the 4th line in the first set of code. I can't seem to find any idea why it keeps giving me that error or what to do to fix it, obviously. The second part of code is the declaration of the function I'm trying to call.

Just checking the basics, did you include your .h file in the .cpp file? Other then that, I can't see any reason why. Unless you have the class declaration in your CPP file and it's after the first call to list::append. BTW, Append is a C++ function already so you might try changing the name.

You're trying to call the function, so you don't need to specify the "char" data type there. In C++, you specify data types on parameters in function declarations and definitions, but not at call sites.

Yes, the .h file is included. And the class is declared in the .h file, but the function later defined in the .cpp file. Oh, and just to check, when it's defined, I do define it like this, right?

int list::append(char line[])
{
what it does
}
 

I get this error when I remove the char from the call of the function.

main1.cpp:31: error: expected primary-expression before ']' token

		char * line;  //define the char* line
		list List //get a pointer to your class

		 cout << "What do you wish to append?"<< endl; //easier to read if you keep it on the same line
		 cin  >> line;
		 list::append(char line[]); //Why would you do this??  This is like declaring the function, not calling it.
				 // Should be like this
		List.append(line);
				 
	}

class list

{

	public:

		  list();

		  ~list();

		  int append(char line[]);

		  int remove(char line[]);
};  //You forgot this.....

All right, yeah, I know I forgot the }; at the end of the class, that's because the class didn't actually end there, that was the only part of it I felt necessary to post to get the point across. And after having changing the thing you mentioned it has fixed it. Thanks to all of you. I guess I forgot a bit of stuff since I took my previous C++ class.

Thanks again, oh look, it actually compiled.
