# Thread: recursion

1. ## recursion

how can i draw a square using a recursive function???

2. ## like that

Code:
```*****
*   *
*   *
*   *
*****```
????

3. this is how i draw sqaures:

Code:
```

#include <iostream>

// Rectangle class declaration

class Rectangle

{

public:

// constructors

Rectangle(int width, int height);

~Rectangle(){}

// overloaded class function DrawShape

void DrawShape() const;

void DrawShape(int aWidth, int aHeight) const;

private:

int itsWidth;

int itsHeight;

};

//Constructor implementation

Rectangle::Rectangle(int width, int height)

{

itsWidth = width;

itsHeight = height;

}

// Overloaded DrawShape - takes no values

// Draws based on current class member values

void Rectangle::DrawShape() const

{

DrawShape( itsWidth, itsHeight);

}

// overloaded DrawShape - takes two values

// draws shape based on the parameters

void Rectangle::DrawShape(int width, int height) const

{

for (int i = 0; i<height; i++)

{

for (int j = 0; j< width; j++)

{

std::cout << "*";

}

std::cout << "\n";

}

}

// Driver program to demonstrate overloaded functions

int main()

{

// initialize a rectangle to 30,5

Rectangle theRect(30,5);

std::cout << "DrawShape(): \n";

theRect.DrawShape();

std::cout << "\nDrawShape(40,2): \n";

theRect.DrawShape(40,2);

return 0;

}```
