Adding side length to task for square

[Rbroke]

I am suppose to:
Create an instance of Square, called s1,with a side length of 5.
Print the side length of s1.
Print the area of s1.
Print the perimeter of s1.

Got it printing but I can't figure how how to set side length to 5.

         Square* s1 = new Square();
	cout << "Details of s1:" << endl;
	cout << "side length: "<< s1->getSideLength() <<endl;
	cout << "area: " << s1->getArea() << endl;
	cout << "perimeter:" << s1->getPerimeter() << endl;
	cout << "     "<< endl;

# include <iostream>
using namespace std;

# define pi 3.14
class square
{
    int side;

    public :
        square(void){side = 0;};
        square(int s){side = s;}

        int getSideLength(){return side;}
        float getArea(){return side*side*pi;}
        float getPerimeter(){return 2*side*pi;}
};

int main()
{
    square* s1 = new square();

	cout << "Details of s1:" << endl << endl;
	cout << "side length: "<< s1->getSideLength() <<endl;
	cout << "area: " << s1->getArea() << endl;
	cout << "perimeter:" << s1->getPerimeter() << endl;
	cout << "     "<< endl;

    delete s1;// Dont forget to delete

	square* s2 = new square(5);
	cout << "Details of s2:" << endl << endl;
	cout << "side length: "<< s2->getSideLength() <<endl;
	cout << "area: " << s2->getArea() << endl;
	cout << "perimeter:" << s2->getPerimeter() << endl;
	cout << "     "<< endl;

    delete s2;

	return 0;
}

Hope that helps
