## pls help!!!

i have a nassigmet i wrote most of the code but i have a problem with print_diomand_square(int,int,int) it has to be recursive funnction but i cant do this how can i achieve to print a square with a recursive function??

Code:
```#ifndef point_h
#define point_h
int gotoxy(int,int);
void clrscr();
class Point {
public:
Point(int,int);
void setPoint(int,int);
int getx() {return x;}
int gety(){return y;}
void printpoint();
protected:
int x,y;
};

class Line :Point{
public:
Line(int,int);
int  getlength();
void setlength();
void printline();
protected:
int length;
};
class Rectangle: Point {
public:
Rectangle(int,int);
void setheight();
void setwidth();
int getheight();
int getwidth();
void printrectangle();
protected:
int width,height;
};

class Diomand:Point {
public:
Diomand(int,int);
void set_Diomand_length();
int getsquare() {return square;}
int getlength();
void print_diomand();
int print_diomand_square(int,int,int);
protected:
int length;
int square;
};
