drawRectangle() ISSUE!

[opProgrammer]

Hello, before I explain my problem I just wanted to say that I am quiet new to the programming.

I'll be quick and just describe the problem really briefly, I am attempting to create simple rectangle ( square ) on win32 application. I am using CodeBlocks and We have been provided with own library which include <windows.h>.

However when I try to create rectangle using this function:

#include <snake.hpp>
#include "intro_state.hpp"
#include <windows.h>
#include <vector>

void drawRectangle(Pen* pen, int x, int y, int width, int height)
{
    Pen greenPen = new Pen(Color.Green, 3);
    int x = 20;
    int y = 20;
    int width = 200;
    int height = 200;

    // Draw rectangle to screen
    drawRectangle(greenPen, x, y, width, height)
}

I get this error:

..\..\inc\snake.hpp|13|error: 'Pen' has not been declared|
||=== Build finished: 1 errors, 0 warnings (0 minutes, 0 seconds) ===|

My header file for this particular function:

#ifndef _LEVEL_HPP_
#define _LEVEL_HPP_

#include <intro_state.hpp>
#include <vector>
#include <windows.h>
#include <sstream>
#include <string>

class Snake
{
public:
    void drawRectangle(Pen pen, int x, int y, int width, int height);
};

#endif // _LEVEL_HPP_ 

I really hope you guys can help me! I'd really appreciate it.
Thank you

What library are you on about.

I see two immediate issues

1. In this first code, this function appears to be infinite recursive

void drawRectangle(Pen* pen, int x, int y, int width, int height)
{
    Pen greenPen = new Pen(Color.Green, 3);
    int x = 20;
    int y = 20;
    int width = 200;
    int height = 200;

    // Draw rectangle to screen
    drawRectangle(greenPen, x, y, width, height) //also missing semicolon here.
}

2. If the function above is supposed to be the definition (also known as the body) for this function declaration here from the Snake class:

class Snake
{
public:
    void drawRectangle(Pen pen, int x, int y, int width, int height);
};

then the function definition is incorrect
it should be

void Snake::drawRectangle(Pen* pen, int x, int y, int width, int height)
{
     void drawRectangle(Pen* pen, int x, int y, int width, int height)
{
    Pen greenPen = new Pen(Color.Green, 3);
    int x = 20;
    //...... other code here
    
}
}

But we are still stuck with the definition/declaration of Pen.
Where (in what header file) is the declaration for Pen ???????

What I mean't by saying "own library " is that our tutor have provided functions specially designated for our project. Which is very, very similar to <windows.h> library.

Coming back to the Pen, I thought its part of GDI library?

I would really appreciate any help or just a point into right direction to resolve this issue .

Thank you !
