Thread: Functions and Classes - What did I do wrong?

Ok, this is where I'm at now:

Code:

//this is my coding

#include <iostream>
#include <iomanip>

using namespace std;

class rectangle {
    private:
    double Width, Lenght;  
  public:
	  rectangle () {Width = 1.0, Lenght = 1.0;}; 
    rectangle (double,double);
    double area (void) const {return (Width*Lenght);}
    double perimeter (void) const {return (Lenght*2 + Width*2);}
    void setWidth(double x);
    void setLenght(double y);
    double getWidth() const;
    double getLenght() const;

	
};

void rectangle::setWidth(double x;)
{
    if ((x < 0.0;) || (x > 20.0;))
	{
		Width = 1.0;
	}
	Width = x;


}

void rectangle::setLenght(double y;)
{
    if ((y < 0.0;) || (y > 20.0;))
	{
		Lenght = 1.0;
	}
Lenght = y;

}

int rectangle::getWidth()
{
   return Width;

}

int rectangle::getLenght()
{
   return Lenght;


}


//this is what was given
int main()
{
	rectangle a, b(4.0,5.0), c(67.0, 888.0);
	cout<< setiosflags(ios::fixed | ios::showpoint);
	cout<<setprecision(1);

	cout<<"a: length = " << a.getLenght() << "; width = " << a.getWidth()
                                            << "area = " << a.area() <<'\n';

	cout<< "b: length = " << b.getLenght() << "; width = " << b.getWidth() 
                                                     << "; perimeter = " << b.perimeter()
                                                     << "; area = " << b.area() << '\n';

	cout << "c: length = " << c.getLenght() << "; width = " << c.getWidth() 
                                                      << "; perimeter =" << c.perimeter() 
                                                      << "; area = " << c.area() << endl;

	return 0;
}
