Question

1. (20 points) Create a new project named hw4_lastname and create a class named Rectangle that represents a rectangle (1) Your member variables will be height and width. (2) Your member functions will be setHeight (double h): mutator for height variable setWidth (double w): mutator for width variable setDimensions (double h, double w): sets both height and width getArea () : returns the area of your rectangle getPerimeter: returns the perimeter of your rectangle print): prints a rectangle with your dimensions composed of asterisks (3) Create a default constructor that sets the default values of Rectangle class to 0 Make sure that the mutators for height and width only take positive numbers! Test your class with the driver program given below //-- Test driver for class Rectangle #include using namespace std; int main () Rectangle recl, rec2, recl.setHeight (10) recl.setWidth (20) rec2.setDimensions (5, 10) cout

Explanation / Answer

class Rectangle
{
public:

   double height, width;

   void setHeight(double h)
   {
       height =h;
   }

   void setWidth(double w)
   {
       width = w;
   }

   void setDimensions(double h, double w)
   {
       height = h;
       width=w;
   }

   double getArea()
   {
       double a=height*width;
       return a;
   }

   double getPerimeter()
   {
       double a=2*height + 2*width;
       return a;
   }

   void print()
   {
       for(int i=0;i<height;i++)
       {
           for(int j=0;j<width;j++)
           {
               cout<<"* ";
           }
           cout<<endl;
       }
   }
};
