The old 'turtle' program....help with it compiling to start

I am working a variation of the 'turtle' program.

I was given this code by the instructor, and I just want it to compile first, but I am getting these errors using Studio 08.

Code:

//Turtle.cpp
#include <iostream>
using namespace std;
#include "TurtleGraphics.h"

int main()
{
   int cmds[] = {5,5,4,5,9,2,5,12, 1,};     // go to start of page and put pen down

   TurtleGraphics turtleOne;  // create a TurtleGraphics object

   turtleOne.processTurtleMoves(cmds); // have turtle process commands

cout << "end of program\n\n"; // for testing purpose

   system("pause");
   return 0;  // we are finished, let's go home
}

Code:

//TurtleGraphics.h
#pragma once

class TurtleGraphics
{
private:
	const static int NROWS = 22; 
	const static int NCOLS = 70;  

	const static int STARTING_ROW = 0;   
	const static int STARTING_COL = 0;   

	const static int STARTING_DIRECTION = 6; //12 = up, 3 = right, 6 = down, 9 = left

	const static bool STARTING_PEN_POSITION = false; 

	void displayFloor();  // will display floor on the screen

	bool m_Floor [NROWS][NCOLS];   // floor on which turtle will draw

public:
	TurtleGraphics(void); //ctor will init. floor to all "false" values, 
	                      
	void processTurtleMoves( const int commands[]);  
              
	
};

So where is TurtleGraphics.cpp to match your TurtleGraphics.h file?

If you have such a file, then you need to add it to the project->settings->source files list (along with your Turtle.cpp)

If you don't have such a file, then it should be in a library somewhere, given to you by your tutor.

I am not sure that I require a TurtleGraphics.cpp file.

it compiles now - I changed

in the TurtleGraphics.h file

Code:

void processTurtleMoves(const int commands[]);

to

Code:

	void processTurtleMoves(const int commands[]) 
	{

		return;
	}

Well yeah, except processTurtleMoves() probably did something, and now it does nothing.

The real something will be in the .cpp file you're so keen to dismiss as irrelevant.
