error: No matching function for call to my class object

Maybe I am initializing it incorrectly? Preety sure this is how our teacher showed us how to do it.. but im stumped. I am trying to use the function as an accessor and get the data and display what is already stored in the struct "coordinate" under the member "Entrance"

Header file:

#include <iostream>
#include <cstdlib>
#include <fstream>
using namespace std;

#include "type.h"
const int MAX = 50;
#ifndef MazeClass_H
#define MazeClass_H

class MazeClass
{
    private:
        SquareType Maze[MAX][MAX];
        coordinate      Entrance, Exit;
        int     height, width;
    public:
        MazeClass();
        void    ReadMaze(ifstream&);
        void    DisplayMaze();
        void    GetEntrance(coordinate);
        void    GetExit(coordinate);
        void    MarkVisited(coordinate);
        void    MarkPath(coordinate);
        bool    IsWall(coordinate);
        bool    IsClear(coordinate);
        bool    IsPath(coordinate);
        bool    IsVisited(coordinate);
        bool    IsExit(coordinate);
        bool    IsInMaze(coordinate);
};
#endif

Implementation file:

#include "MazeClass.h"
#include <iostream>
#include <cstdlib>

char maze[50][50];
MazeClass::MazeClass()
{
}

void MazeClass::ReadMaze(ifstream& myIn)
{
    int x, y;
    myIn >> x;
    myIn >> y;
    height = x;
    width = y;
    myIn >> x;
    myIn >> y;
    Entrance.row = x;
    Entrance.col = y;
    myIn >> x;
    myIn >> y;
    Exit.row = x;
    Exit.col = y;
    myIn.ignore(100, '\n');
    for(int i = 0; i < height; i++)
    {
        for(int k = 0; k < width + 1; k++)
        {
            myIn.get(maze[i][k]);
            if(maze[i][k] == '*')
                Maze[i][k] == Wall;
            else
                Maze[i][k] == Clear;
        }
    }
}

void MazeClass::DisplayMaze()
{

    for(int i = 0; i < height; i++)
    {
        for(int k = 0; k < width + 1; k++)
        {
            cout << maze[i][k];
        }
    }
}

void MazeClass::GetEntrance(coordinate Entrance)
{
}

void MazeClass::GetExit(coordinate Exit)
{
}

and my file to try and use it:

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


int main(int argc,char *argv[])
{
    MazeClass maze;
    ifstream myIn;
    int x,y;
    string filename = argv[1]; // command line arguement stuff

    myIn.open(filename.c_str());
    maze.ReadMaze(myIn); //reads in the maze from a data file
    maze.DisplayMaze();
    cout << "The entrance is at: " << maze.GetEntrance().row << " " << maze.GetEntrance.col << endl;
    myIn.close();

    return 0;
}

and im getting this error:

ola4A1.cc:17: error: no matching function for call to ‘MazeClass::GetEntrance()’
MazeClass.h:21: note: candidates are: void MazeClass::GetEntrance(coordinate)
ola4A1.cc:17: error: ‘maze.MazeClass::GetEntrance’ does not have class type

I have tried placing coordinate in like this:

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


int main(int argc,char *argv[])
{
    MazeClass maze;
    ifstream myIn;
    int x,y;
    string filename = argv[1]; // command line arguement stuff

    myIn.open(filename.c_str());
    maze.ReadMaze(myIn); //reads in the maze from a data file
    maze.DisplayMaze();
    cout << "The entrance is at: " << maze.GetEntrance(coordinate).row << " " << maze.GetEntrance(coordinate).col << endl;
    myIn.close();

    return 0;
}

but i THEN get the error:

ola4A1.cc: In function ‘int main(int, char**)’:
ola4A1.cc:17: error: expected primary-expression before ‘)’ token
ola4A1.cc:17: error: expected primary-expression before ‘)’ token

AFTER which... I added in "Entrance" like so..

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


int main(int argc,char *argv[])
{
    MazeClass maze;
    ifstream myIn;
    int x,y;
    string filename = argv[1]; // command line arguement stuff

    myIn.open(filename.c_str());
    maze.ReadMaze(myIn); //reads in the maze from a data file
    maze.DisplayMaze();
    cout << "The entrance is at: " << maze.GetEntrance(coordinate Entrance).row << " " << maze.GetEntrance(coordinate Entrance).col << endl;
    myIn.close();

    return 0;
}

and it gives me this error...

ola4A1.cc: In function ‘int main(int, char**)’:
ola4A1.cc:17: error: expected primary-expression before ‘Entrance’
ola4A1.cc:17: error: expected primary-expression before ‘Entrance’

So YES... I am stumped...Any help would be greatly appreciated! I have been trying to figure this one out for an hour now :(

You want to acces member variables of variable Entrance in main. i think what you need is this

coordinate MazeClass::GetEntrance()
{
   return Entrance;
}

And change you function prototype in header file accordingly.

With this modification your below statement will work fine (check () for calling col)

cout << "The entrance is at: " << maze.GetEntrance().row << " " << maze.GetEntrance().col << endl;

Change your GetExit function also like this for using it
