Operator overloading error when called "name not allowed in member function"

[Nitrosolid]

I created an overloaded but i am getting weird errors when i call it. I am very new to pointers so I have no clue where to look.

Artist.h

  #pragma once
#include <string>
#include <iostream>

using namespace std;
//Artist Class Definition.
class Artist
{
public:
	//Defualt Constructer 
	Artist::Artist();
	// Getter Function.
	string getName();
	string getCountry();
	// Set Function
	void setName(string);
	void setCountry(string);
	~Artist();
	Artist&Artist::operator=(const Artist& p);

private:
	string *firstName;
	string country;
};

Artist.cpp

#include <string>
#include <iostream>
#include <fstream>
#include "artist.h"

using namespace std;

//Default Constructer
Artist::Artist() {
	//Now a pointer.
	*firstName = "";
	country = "";
}

Artist& Artist::operator=(const Artist& p) {
		firstName = p.firstName;  
		return *this;
	
}//end operator=

//Deconstructer
Artist::~Artist() {
	delete firstName;
}
//Set & Get Functions
void Artist::setName(string f) {
	*firstName = f;
}

void Artist::setCountry(string c) {
	country = c;
}

string Artist::getName() {
	return *firstName;
}
string Artist::getCountry() {
	return country;
}

main.cpp

#include <string>
#include <iostream>
#include <fstream>
#include "song.h"
#include "album.h"

int main() {
	//Variables.
	string option;
	string file_name;
	Album myalbum;
	bool active = true;

	Artist theArt;
	theArt.operator=;
}

Why are you using a pointer at all here?

[Repeater]

In the class declaration, don't put Artist:: before function names.

Nothing to do with pointers. You just wrote the class declaration wrongly.

using namespace std; Do not ever put this in your header files. Ever.

Thanks.But i just decided to get rid of it. I am using a pointer because my assignment is to add pointers to my static library I made. It's tougher then i thought it would be :/.
