Request for member ... which is of non-class type

Question

I am trying to switch from functional programming to object oriented, however I am running into an error while trying to call a member function from within a class.

The code is as follows:

GameFinal.h

    #ifndef GAMEFINAL_H
#define GAMEFINAL_H
using namespace std;
#include <string>
class TicTac
{
    public://MEMBER FUNCTION DECLARATION
    
    void printBoard();
    bool playerMove(int play);
    int checkWin();
    void player_turn();
    void game();
    void player1Info();
    void player2Info();

    protected:
    char xo;                                                                            
    int play, player_win;                                                                                                                                                                   
    std::string player1, player2;
            
};

#endif

GameFinal.cpp

#include "GameFinal.h"
#include <iostream>
using namespace std;




void TicTac::player1Info()
{
    cout << "Enter name for player 1: \n";
    
}

MainGameFinal.cpp

#include <iostream>
#include "GameFinal.h"
using namespace std;

int main (){

TicTac player1();
player1.player1Info();





    return 0;
}

The functional code in which I am trying to convert into object orientated looks like this

#include <iostream>
using namespace std;

char tictacBoard[3][3]= {{'1', '2', '3'}, {'4', '5', '6'}, {'7', '8', '9'}}; 
char xo;                                                                            
int play, player_win;                                                                                                                                                                   
string player1, player2;

void printBoard();
bool playerMove(int play);
int checkWin();
void player_turn();
void game();
void player1Info();
void player2Info();



int main ()
{
player1Info();
player2Info();
game();


}





void printBoard()
{
    cout << " " << tictacBoard[0][0]<< " | " << tictacBoard[0][1]<< " | " << tictacBoard[0][2]<< endl;

    cout << "-------------\n";
    cout << " " << tictacBoard[2][0]<< " | " << tictacBoard[2][1]<< " | " << tictacBoard[2][2]<< endl;

    
}

bool playerMove(int cord)
{
    int row = cord /3;
    int col;
    
    if(cord % 3 == 0)
    {
        row = row - 1;
        col = 2;
    }
    else col = (cord %3) - 1;
